Original review: Oct. 12, 2018 2018 Mercury 150 with 8 hrs had water getting in crankcase. They replaced complete outboard 2 weeks on repair, new 2019 replacement would only get 5000 rpm at 49 mph (first motor ran 5600 rpm at 56 to 58). It is going on 5 weeks and counting, still not fixed. They first said cam time was off a tooth, (striped bolts out on repair) didn’t fix it, put new control module (computer) on it, didn’t fix it, smaller prop got rpms to 5750 no more speed, basically to cover up problem. Called Mercury several times.

Had to cancel vacation fishing trips. Mercury and Tracker just pushes everything off on dealer saying they are not on the purchasing end and the dealer is doing what they tell him to do to stay in compliance with warranty. Original review: Sept. 23, 2018 Bad reviews are easy to make, when you have problems with any product. I would like to say that my experience with my 1978 Mercury 20 hp has been very good. Purchased brand new in March 1978, this motor has dependably powered my 14 ft. Sea Nymph aluminum boat for 40+ years.

Switched to Amsoil two stroke oil, this gem of an engine runs clean and smooth. Still produces 120 lbs. Compression on both cylinders. Four years ago I had fresh wiring and a new switch box installed. Spark plugs, fuel lines and replacement fuel tank are the only other maintenance items.

Mercury Dealership says that if I keep doing what I’m doing, the engine will outlive me. Sorry guys, I don’t need a new Mercury, my old one won’t die! After several outings where the same thing happened and various solutions were pursued, the mechanic was finally able to replicate the problem in his shop and determined it is a faulty fuel pump. However, it is now out of warranty. Despite the problem arising during the warranty period, Mercury refuses to compensate me for the repairs that have now totaled over 40% of the original price of a new engine. If I knew about such fraudulent incompetence, I would never have purchased a Mercury engine. Now here, a potential customer of Mercury is forewarned.

Original review: Aug. 16, 2018 I bought a 3.5hp Mercury in the spring of 2016 from Bass Pro in Vaughan Mills, but it always dies on me after about 10 mins running. It's also very hard to start it (normally have to pull more than 20 times). I got the call back letter after a tough summer.

It said the fuel pump may not have been properly assembled. They wasted me a entire summer, but they didn't give me any compensation. But now it didn't work again. It always dies after 1 min running now.

So yesterday I dropped it to the service centre at Bass Pro Vaughan Mills. When I came to pick up it today, they wanted to charge me $120! The guy said they changed two spark plug and my 3 year warranty does not cover it. A two years old motor need a spark plug change? Do you believe it?

Looking for R2015d Service Manual do you really need this pdf R2015d Service Manual it takes me 14 hours just to obtain the right download link, and another 5. R2015d service manual.

Even if it's true, it's a problem of the product quality. Why doesn't the warranty cover it? Resolution response: Aug.

4, 2018 Well, I went to pick up my motor from a dealer, thinking I was going to pay for a new carb. However, the mechanic met me and explained that it was not the carb, or anything else I had changed.

There was one bad plug. It was running off one plug out of the water, and in the water bogging down. He told me this was very rare. The engine didn't have 10 hours on it, and I had checked the plugs, and they looked fine. Was told, 'You can't tell by looking at them and checking the gap. Something happens out of sight.'

So, got boat back in the water, and eureka. It runs just fine. Three summers of agony and frustration over. Thought to be fair I better update my previous complaint and hopefully help anyone else who might possibly have the same problem.

Original review: July 8, 2018 Mercury 8HP, 4 stroke - Bought this motor along with a boat new in 2012. Had starting problems from the start. Then it started bogging down after accelerating.

2004 Mercury 50 Elpto Manualidades

Called dealer. Out of business. Read many posts as to what the problem could be. Tried Seafoam.

Had carb cleaned (wasn't dirty, barely used). Changed plugs, filter and had fuel pump tested. Still no change. Ran well on land with water hose attached. As soon as in water it bogs downs. Went into another Mercury dealer. The tech said it's the carb.

I said it has been cleaned by a technician. He said they throw them away. Can't be cleaned as jets so small, and the ethanol in gas ruins them.

A new carb and installation around $500. Not sure whether to chuck good money after bad. This engine wouldn't have 10 hours on it, cost around $2,550.00, and I find from the serial number labels that it was made in 2007. Seems like the dealer who sold this to me knew I was getting an old lemon. No wonder now out of business. Totally frustrated with this Mercury outboard, and would never buy a Merc engine again.

In fact I think I will go back to my canoe and kayak. Original review: July 6, 2018 I recently purchased a 2008 Triton bass boat with a Mercury Optimax 150 and only 14 hours on it. I bought it from a coworker who had purchased it in 2011 and never used it a single time. It sat in a climate controlled storage area for 7 years, and he was moving after retirement to Philadelphia and decided to sell the boat.

I bought it with the perception that it was basically still a new boat! Well I was surprised that after having it checked out by a Mercury mechanic, that fuel pumps, alternator, water pump, gas lines, etc. Needed to be replaced. $2500 worth of repairs just to start out! Then I took it out for the first time and it ran great.

Second time it shut down while running on plane. Found out a coil went bad and wiped out the PCM with it. $3000 in parts to fix! I called Mercury and initially they said the boat was 10 years old and I wasn't the original owner so they could do nothing to help me. Then they called me back and told me they would pay for the PCM ($2200).

I gave him the name of the Mercury Premier service shop and they authorized to pay the bill for the parts and they agreed to pay for the coils, all 6 of them! They completely stand behind their product and admitted that they had an issue with the coils back during the year that's engine was built. Thanks to them my boat is now what I expected it to be, and will be a Mercury customer from now on! Original review: June 11, 2018 Bought new 2015 Mercury 9.9, nothing but starting issues from day one. 2 months old used once, put up for winter, I run stabil in main tank, ran dry used Cfoam, wouldn't stay running if choke was off, brought in dealer, said carb dirty. $100.00 not warrantied.

Next year same thing, always stored inside in basement. I did for that time, $100.00 again ugh!!! 3rd year said.

run dry and leave it, spring started right up ummm, then ran for hour and quit, pic shows problem. I ask dealer if it was warrantied, NO again. Been Mercury owner for years, probably not again. Original review: June 7, 2018 Stay away from Mercury outboards (Four Stroke 150). After less than 40 hours run time, using only non-ethanol gasoline, the motor started losing power, and eventually stalling. I went through the normal diagnosis steps, removed anti-siphon valve, replace low pressure filter, installed an external test tank.all no-go.

I did find a crack on their 'Quick Connect' hose leading from the harness to the low-pressure filter, which could have been sucking air. Bypassed that, still no go. This is a problem that Mercury has known about literally for years, and still can't seem to find a solution to it.

Maybe they just need to buy their fuel pump assemblies from a manufacturer that actually knows how to design something? I had to tow the boat 60 miles away to find an authorized shop that wasn't backed up 4 to 6 weeks (with Mercury problems). They tore it down immediately, and indeed, found the fuel delivery module shot.

Of course, Mercury has them on back order, and aren't going to ship any for at least two weeks, if then, so I'm losing a month or more of the summer due to a crappy design that cannot be fixed even after at least half a dozen re-designs of their fuel delivery module. Stay away from Mercury. Updated on: Well, I got the boat back from the service shop, after the fuel pump failure, and was actually able to use it for about two weeks. Then the alternator died. I called all service shops in the area, and some outside of it, none can take it any sooner than 3 to 4 weeks!

I pulled the alternator myself, and brought it to a local rewinding shop, they can't fix it because of the idiotic integrated rectifier/regulator that are shorted. This also caused a failure of one of my batteries by causing a cell reversal through the rectifier. Now, trying to find the replacement alternator is next to impossible, nobody stocks them, and Mercury won't honor a warranty on this since I'm not going to give up a month of summer boating for yet another one of Mercury Marine's problems. IF I can find one, I'm going to have to spend upwards of $300, and maybe get it in a week or two. STAY AWAY FROM MERCURY MARINE MOTORS!

THEY ARE NOTHING BUT GARBAGE! Original review: May 22, 2018 I purchased a 2018 tracker grizzly with a 60 HP Mercury Outboard from Cabelas in Prairie on April 13, 2018. Within 1 week after registering my Mercury, I received a recall notice letter from Mercury on the fuel pump. It was then taken to Cabelas boat service center and told the fuel pump would be replaced within a week. To date, not replaced.

To date, no idea when it will be replaced. I was told part is ordered. Mercury had to have known that the fuel pump on my 60 HP was defective when I purchased I but was never told about it until 1 week after purchasing a nice fishing boat that has only felt rainwater and not 1 drop of river water. Go Honda or Yamaha. Original review: May 12, 2018 My opening day of fishing at Crowley Lake was ruined when my 2007 Mercury 225 Verado outboard cratered.

I had just had the motor serviced at my local Verado certified service center. Took boat out on local lake and it ran just fine as it always has in the past. Drove 7 hrs to Crowley for the 2018 opener and when boat was launched it was running rough and died when put in reverse. Restarted and tried forward, was surprised when engine revved up and ran my 2007 Lund 1950 Tyee Magnum right up the launch ramp. The motor was stuck in gear and would no longer start.

Took it back to service center and after 2 days of troubleshooting the conclusion was a bad Power Train Control Module. This part is well over $6,000.00. I contacted Mercury to see if they were interested in helping me with the cost or even if they wanted to find out why a $6,000.00 part failed. They of course could care less because it was out of warranty.

Still waiting to get boat out of repair shop. Contacted dealer where I purchased boat and they told me they had never replaced a Power Train Control Module so this is a rare issue.

Needless to say I'm extremely disappointed with Mercury Marine. I will update when I get the boat repaired.

Original review: May 8, 2018 225 Pro XS - Well I am not sure that one more bad review is going to make a difference, but I sure wish I had seen this before I bought this POS that I did, of course it started right out of warranty that it blew the #3 injector, the shop replaced it and it lasted a short time and then it blew the injector again, this time replaced the injector and the PCM. Now we have replaced the injector a third time and replaced the wiring harness and you guessed it.

Mercury could care less, they will not do anything to help, they even went as far as to point out that I had a 2 year extended warranty and that was 2 years more than most get. Original review: Dec. 6, 2017 Mercury 225 Pro XS. In the early part of 2017 I decided to purchase a new outboard for my Grady-White. For the last 16 years it was powered by a 200 OX66 Yamaha which served me trouble free and still looked as good as it did when it was new. My first problem showed on the trial run even before I took possession of the motor. The buzzer sounded and the thermostat failure flashed on the smartcraft gauge.

The installer plugged the motor into his laptop and it showed that it was a low temperature alarm. The thermostats were replaced and soon after the same thing happened again. This time the installer checked the poppet valve and told me it good to go.

Soon after the same thing happened again. This time I was told it was not a big deal and not to worry about it.

I asked if a Mercury service rep could be contacted to see if they could diagnose the problem. I was told by my installer that they would contact Mercury and get back to me as soon as they contacted one. That was around the end of April 2017. As the water warmed in the spring and summer months the problem was not as bad. The motor temp would stay high enough to keep the alarm from sounding.

As the fall approached and the waters began to cool the same thing happen again. I contacted Mercury again and again with no luck.

Finally Mercury told me of a kit I could have installed which would block off the low water pickups in the front of the lower unit. I purchased the Mercury plugs and had intended to have them installed as soon as I pulled the boat out for the winter. As if all of this was not bad enough, when I pulled the boat in November 2017 I found that the lower unit where the low water pickups are located had corroded into one large hole which was around three quarters of an inch in diameter.

I contacted Mercury about two weeks ago and I am still waiting for that service tech to arrive. I will never buy American again! I should have dealt with the extra weight of a Yamaha four stroke and not wasted my hard earned money on a total piece of trash. President if you really want to make America great again, you might want to start by letting the Japanese in to manufacture our products. Resolution response: Dec.

12, 2017 This issue I had is resolved I hope. Since August 2nd when I bought this boat it has about 3 months of shop time to date. Got it back on Dec 8. Took it out today and it ran better than the day I got it. Hope it lasts. They had to replace the gas tank, flush all lines and I suppose put in new fuel filters. It runs to 6000 rpm and it would never go over 5000 rpm before.

Very satisfied with the results. Hope this helps someone make a decision about repair time that Mercury took to get this right. Original review: Nov. 5, 2017 On August 2nd, I bought a 2017 Suntracker pontoon boat powered by a new Mecury 115 CT motor. I used this boat 8 hrs and got stuck. Motor seemed it was like a car running out of gas surging above idle.

2004 Mercury 50 Elpto Manual

Brought to dealer. The boat was kept 6 weeks and they said a fuel cell repair was done.

Got the boat back and it ran about a half hour before surging started. Called dealer. Was told to put a fuel water separator filter between fuel tank and motor. Used boat again, constant surging above idle. Put a new filter on and tried again. Brought back to dealer, was run on a hose at dealer and did same thing. This is where I stand now.

Will keep everyone posted on outcome. If there is a third time I will sue under the Lemon Law. Boat was bought at Nobles Marine in Crystal River FL. Original review: Oct. 15, 2017 I purchased a new 20 hp outboard with a 5 year warranty. During the second year it started to have multiple issues which includes massive amounts of black smoke, serious starting issues, great difficulty shifting gears, loud banging sounds when doing so, low oil pressure light illuminating, loss of power. I attended at numerous dealerships for these issues and after 5 years of fighting with them and having contacted Mercury Marine customer service dept - they begrudgingly replaced the carburetor and the gears in the gear shift.

This was done because I met a dealer with an honest mechanic who contacted Mercury and advised them to provide the parts and to replace them under warranty. The black smoke still prevails and testing has been done which is empirical that this motor is producing about 10 hp. A mechanic has advised that top rpm is 4500 and not the 6100 required.

A Mercury rep, Dave., looked at the motor, ran it in a tank and declared it runs fine and there are no issues (he did not 'see' black smoke). We all know that a tank test does not load a motor. I have provided pictures of the black smoke and data on the test run. did not test run the motor but the Mechanic did who has advised it does not rev up properly under load.

I have been lied to by Mercury Marine and most of their dealer mechanics. I requested that I be present a two inspections and tests but they denied this request and did them in secret without providing or naming the tests they may have performed. I was advised by a dealer/owner and the mechanic that 4 stroke Mercury outboards run much rougher than 2 strokes, and get used to it. Here is the summary of Mercury Marine Warranty - THEY DO NOT HONOR THE WARRANTY AND WILL MAKE YOU MISERABLE AND ANGRY SO YOU WILL GIVE UP - I was told this by a management member of Mercury Marine customer relations dept. This motor has been a 'lemon' - they know it and do not care - reading other reviews I see this as corporate policy. Caveat Emptor.

Original review: Sept. 22, 2017 I have a 2011 walkaround with a 2010 Mercury Verado 150. The motor ran fine for a few years with no problems.

In June 2016 the motor quit like it ran out of gas. Issue found, bad float sensor and bad high pressure fuel pump. Replaced with new improved float sensor and high pressure fuel pump. A few months later, towed in again, bad fuel float sensor!!!

More money, ran the boat a few times and put away for winter. July 2017 ran the boat, it ran fine for the day. Thought the problems were all solved. A month later went to go fishing. The boat started fine, headed out, motor ran a little ruff.

Here we go again, motor stalled like it ran out of gas!!! I pulled gas line, no fuel again!!! Mercury Marine claims ethanol issues!!! Why build a motor that can't run on today's fuels!!! So here we go again with maybe bad float sensor and maybe bad fuel pumps, dealers thoughts. This motor has become unsafe!!!

DO NOT BUY MERCURY OUTBOARDS!!! Do yourself a favor Google Mercury outboard problems before you buy!!! Original review: July 31, 2017 Although a while ago it would appear no lessons have been learned by this shocking company. Firstly assuming maintenance protocol is followed no marine engine should suffer failures any more than a car engine, which, is used far, far more and subject to thousands of hours of stop, start, racing, cruising, reversing and so on, did you know that Honda have built 28 million, yes read that again 28 million v tech engines and not a single failure, think on that. Now my story, I had a Yellowfin with 3 x 275 HP Verado's, in 2009 the ECU units failed on 1 engine, diagnosing the fault it was noted there was a factory upgrade, thanks for writing to me Mercury (not) the parts had to come from Belgium. 5 weeks later they arrived, the beautiful weather had gone, just about the only thing Merc were not responsible for, then having fixed the ECU's a fuel management problem occurred. So summer 2009 written off.

Here is the thing, agents and dealers will tell you that after 13 years the bugs have been ironed out, yes the immediate bugs have however the quality of componentry has not and catastrophic failures come about through the 'penny worth of tar' principle, Mercury have a complete disconnect with regards to the ownership experience because they have a stranglehold on the market. Across the board if all out reliability is the name of the game then its Honda or Yamaha, if reliability and performance then Evinrude e-techs. The issue is dealer numbers and that dear readers is why Merc get away with it. Original review: July 23, 2017 (2017 250Optimax) Motors brand new. Not reliable at all.

The boat has been in to the dealer at least once a week for various problems. Dealer has been very cooperative however the quality of this engine is subpar. The trim cylinders on the port motor has to be replaced, because the engine does not stay up in position. The starboard engine quit at 1500 rpms in the ocean. Alarms sounded but it's not overheating or needs oil. Something else is wrong.

When the dealer took off the hood on the engines we noticed salt over the entire block on both motors. Somehow water is getting past the gaskets that are supposed to seal the hood to the motor.

VERY POOR QUALITY CONTROL IN MANUFACTURING. MADE IN AMERICA. I SHOULD HAVE KNOWN BETTER. Original review: July 16, 2017 Sold my '89 20 HP Evinrude 2-stroke in June of 2015. I figured a four stroke would be cleaner and smoother running so I bought a 2015 Mercury 20 HP 4-stroke that same month. I was pretty happy with it except for the vibration at the tiller handle at any speed except full throttle or idle speed.

That surprised me but after the break-in that first season those were the speeds I typically used so it wasn't a big issue. I am a retired engineer in my 60's and pay close attention to the operation and maintenance manuals of pretty much anything I buy, especially expensive ones. This year, June 2017, it wouldn't start, fresh fuel, new plugs, no go.

I took it to my nearest authorized Mercury dealer, Richardson's Boat yard (not where I bought it) for service. I have a 5 year warranty so I wasn't too concerned money-wise. They called me two weeks later with an estimate of about $750 to replace the carburetor, plugs, and fuel filter plus $100 for the diagnosis.

I told them I was only two years into a five year warranty. They told me that the plugs were fouled and the carburetor was gummed up due to 'fuel problems' that Mercury wouldn't cover since this was not considered a defective part. I called Mercury customer service and explained that I had followed their operation and maintenance recommendations to a tee and the motor only had about 25 hours on it. I also let them know that owned my Evinrude for 27 years, never needed service, and was still going strong when I sold it. They said that 'fuel issues' were not covered and that unless the dealer found a defective part they couldn't help me. The attitude of both Richardson's and Mercury was that I must have done something wrong to cause the problem. Guilty until proven innocent I guess.

So I authorized the work and asked for the old parts when they were done. The final bill was around $860. The carburetor they replaced was clean as a whistle, like it just came out of the box and there were modifications to the OEM fuel lines on both tanks that were not on the original estimate which I found curious. I challenged them on the carb replacement but they insisted the problem wasn't something you could see. I had to pay to get my boat having lost all of June. I was still pretty mad about the whole thing so I contacted Mercury again and asked them if there was some place I could send the carb to have it tested like maybe their manufacturer. Their response, once again was worthless.

So, I just spent $860 to fix a 2 year old Mercury that cost me less than $3000. Put in perspective, it's kind of like buying a $30,000 car and having to pay $9000 in repairs while it was still under warranty.

Hopefully I can sell it and get something else. This whole experience with a Mercury product and their customer service was awful. I would not recommend them to anyone. After many trips back to the dealer and many bad trips out fishing, the engine finally blew up, in the middle of an ocean bar. Luckily we were able to be towed back in. The engine had thrown something through the block.

Mercury are now saying that I put the boat into reverse at high speeds, or the transducer was in the wrong position, or I performed an emergency stop. These actions have forced water up into the exhaust port and blown a hole in the head. I am 48 and have been operating boats since I was 16. I was offended by the service managers claim because I would not put the engine in reverse at speeds under any circumstances, I didn't got the transducer (fitted by Mercury Authorised dealer), and as for emergency stop, the engine blew up. Of course it stopped.

Mercury has stated that they are going to be generous and replace the motor and the computer. I think, due to the continual issues I have had with this piece of junk, I am well within my right to request that the engine be replaced. These arrogant people can't even be bothered phoning me. The person at Mercury said I should phone them. I am up to $500 with my lawyer fees so far, but I won't let them get away with this. 15K for a new engine that should be hooked onto a rope and thrown over the side as an anchor.

I am now on my third week without a boat which cost me in all around 55K. Mercury has broken a very basic consumer law here in Australia. I want my boat back with a new engine that is tested prior to delivery. My mates, family and my own safety have been placed at risk by the faulty engine.

I have always been a huge fan of Mercury engines and have owned many, but this kind of service has left a sour taste. Original review: July 5, 2017 I am a casual fisherman who bought a Lund 1875 with a Verado 150 in 2012.

There is only 80 hours on this engine and last month the Oil Cooler Module failed and had to be replaced. I contacted Mercury to see if there was recall that I missed and there were none. I contacted customer service and they would do nothing for me. When I drove my new boat and motor to my first fishing trip, the owner of the fishing lodge could not believe that I had actually bought a Mercury Engine. He said that it would fail and that I should have bought an Evinrude or Honda or Johnson or ANYTHING but a Mercury.

It makes me sick to think that after only 80 hours of boating, he was absolutely CORRECT! Original review: June 13, 2017 I have sent a complaints letter to both Mercury's European contact email (bme.service@brunswick.com) and their US one (services@brunswick.com). They happily and completely ignored my messages, and I am still waiting for a reply after over two months. To sum up its contents; I was repeatedly insulted and ultimately threatened by one of their authorized dealers nearby, after a basic engine service. Having had a motorboat for over 10 years, this has frankly never happened to me, and was a highly negative and shocking experience with this brand.

Customer service is definitely not their priority. Mercury Marine has been powering boats for over 75 years. Founded in 1939, the company now has locations around the world.

It is assumed that these personnel are familiar with the servicing procedures of these products, or like or similar products manufactured and marketed by Mercury Marine, that they have been trained in the recommended servicing procedures of these prod- ucts which includes the use of mechanics’ common hand tools and the special Mercury Marine or recom- mended tools from other suppliers. We could not possibly know of and advise the service trade of all conceivable procedures by which a ser- vice might be performed and of the possible hazards and/or results of each method. We have not under- taken any such wide evaluation. Therefore, anyone who uses a service procedure and/or tool, which is not recommended by the manufacturer, first must completely satisfy himself that neither his nor the products safety will be endangered by the service procedure selected.

All information, illustrations and specifications con- tained in this manual are based on the latest product informa tion available at the time of publication. As re- quired, revisions to this manual will be sent to all deal- ers contracted by us to sell and/or service these prod- ucts. It should be kept in mind, while working on the prod- uct, that the electrical system and ignition system are capable of violent and damaging short circuits or se- vere electrical shocks. When performing any work where electrical terminals could possibly be grounded or touched by the mechanic, the battery cables should be disconnected at the battery.

Any time the intake or exhaust openings are exposed during service they should be covered to protect against accidental entrance of foreign material which could enter the cylinders and cause extensive inter- nal damage when the engine is started. It is important to note, during any maintenance proce- dure replacement fasteners must have the same measurements and strength as those removed. Numbers on the heads of the metric bolts and on the surface s of metric nuts indicate their strength. Ameri- can bolts use radial lines for this purpose, while most American nuts do not have strength markings.

Mis- matched or incorrect fasteners can result in damage or malfunction, or possibly personal injury. There- fore, fasteners removed should be saved for reuse in the same locations whenever possible. Where the fasteners are not satisfactory for re-use, care should be taken to select a replacement that matches the original. A marine power product is a combination of many machined, honed, polished and lapped surfaces with tolerances that are measured in the ten thousands of an inch./mm.

When any product component is serv- iced, care and cleanliness are important. Throughout this manual, it should be understood that proper cleaning, and protection of machined surfaces and friction areas is a part of the repair procedure.

This is conside red standard shop practice even if not specif- ically stated. Whenever components are removed for service, they should be retained in order. At the time of instal- lation, they should be installed in the same locations and with the same mating surfaces as when re- moved. Before raising or removing and outboard engine from a boat, the following precautions should be adhered to: 1. Check that flywh eel is secur ed to end o f cra nk- shaft with a locknut and lifting eye is threaded into flywheel a minimum of 5 turns. Conne ct a hoist of s uitabl e st rength to t he lif ting eye.

In addition, personnel should not work on or under an outboard which is suspended. Outboards should be attached to work stands, or lowered to ground as soon as possible. We reserve the right to make changes to this manual without prior notification.
