Mercury Marine

I purchased a new boat 4 years ago with a Mercury 250 pro xs on it. This engine has a 6 year warranty and now it has a blown power head. Dealer said blew due to a bad fuel injector and it's not covered by warranty. Mercury said because it's a electrical part it's not covered. This is a OEM part and should be covered. This is unacceptable. This engine is only 4 years old and now I have a 65k yard decoration. Mercury has a department to just get out of paying warranty claims. We purchase new boat so we don't have to worry about repairs. I will never buy a Mercury product of any kind again because of this. Don't want to do business with someone who doesn't stand behind their product and has a department to make sure they don't have to.

I purchased a new Ranger Boat in 2018 that came with a Mercury 4 stroke 150 hp. My husband made sure that he kept the maintenance up on his new pride and joy. The boat has 255.5 hours on it and we had to fork out $7,000 to replace the powerhead on it. I am so mad right now. Should have stuck with Yamaha. We have never had any issues with those motors, and we have owned a few. I would not recommend Mercury to anyone. And reading these reviews I see it is a common affair.

I have always used the fuel that the manual recommends, "regular 87 fuel with up to 10 % ethanol", with added stabilizer. I have had the motor back to the dealer every season for failure to start. The 1st time they charged me $160 and found nothing! The second time they charged me $375 to replace the carb float valve. Warranty was refused on carb issues because they can't prove recommended fuel was used. Dealer also told me I should only use ethanol-free fuels. Ethanol has been successfully used in gasoline for decades now, why does Mercury have such issues with it?!? Extremely disappointed.

Purchased a new pontoon with a 115hp Mercury Outboard. Prior two watercraft's had a Yamaha outboard with 15 years of combined service with no warranty claims or repairs outside of normal maintenance. I have the Mercury 5 days / 3 engine hours and my entire family and I get stranded out on the lake. Come to find out the voltage regulator went out and the rocker arm on #4 cylinder was not installed properly from the factory. I questioned my decision when I purchased the boat and now regret not following my instinct to buy another Yamaha. Mercury made the repairs at no direct cost to me but the major inconvenience and obvious insufficient manufacturing quality protocol has me wondering how many times I'm going to regret my purchase in the coming years.

Please share/comment on my problem and help me to solve it. I bought a brand new boat with brand new Mercury 60 HP on Nov, 2020. I could use it only 38 engine hours due its malfunctioning. Authorized service diagnosed it as gear malfunctioning, I asked Mercury company to replace it with a new one cause it was only 3 months passed upon purchase and engine was at below 20 hours. They did not accept it and presented me an only option of replacing the tail. They promised me full replacement if the same problem would happen again. So I accepted it and the tail part was changed.

Head bolts came loose on new motor and they won’t cover it. I paid for the full warranty for 5 years. Called and the guy Cris was very weird acting. Would not even give me his name till I just keep asking.

We are operating a fishing charter in Airlie Beach. Bought a pair of SeaPros 2018 meant to be the new great commercial motors... Gear boxes have been nothing but trouble. Needing a rebuild every 700hr. Motors have done 3000hrs and have been great.. But the gearbox's are a disgrace, using soft cheap steel, jap crap, these "new best ever commercial gearboxes" have been nothing but an ongoing expensive issue, and Mercury don't seem to be able to fix the issue and keep saying it's an operator problem, I had 2 stroke Mercury engines before this and never had an issue, these new lightweight cheap steel gearbox's are not built to last, and all the tour operators in the Whitsundays (300+ boats) have all run away from using Mercury engines. Run away from these engines, thanks A1 Fishing Charters Whitsundays.

I purchased a 2021 17-ft War Eagle boat from Tomahund Marine in Charles City, VA on 9-21-21. On the second use, 11-20-21, the oil light and alarm came on. The oil level was fine. I took it to the dealer & they found metal shavings in the oil which had worked into the oil pressure relief valve and made it stuck in the open position. The motor had run without oil pressure with only 10 hours on the motor. Mercury told the dealer that they would only replace the failed part of the oil pressure relief valve. I called Mercury customer service on 11-30-21 to advise them I was disappointed they would only replace the one failed part that in turn probably damaged the power head of the motor from running without oil pressure.

My father purchased this 25 hp jet drive 4 stroke outboard new, 2 years of very little use it quit running. This motor sat in his garage for 3 plus years then my father passed away leaving me his boat. I took it to Bass Pro a Mercury dealer, they determined bad ECU fuel driver. They also said motor had 18 hours. I purchased and installed new ECU plug and pay 900.00 dollars. The motor ran perfect for 1 year and 5 months, I put about 12 gallons of gas through the motor and it just died from a bad ECU. Motor has about 30 hours on it. I called Mercury customer service and they will not help. This is a hard pill to swallow, another 900 dollars. Wow. This is crazy. I think I will try and sell this piece of crap and buy a Honda or Yamaha. Therefore be warned about these Mercury engines.

Spark plug #4 cannot be replaced easily requiring removal of side cowling. Top cowling hard to fit and rattles. Shift sensor went bad 3 times. Electronic gauge trim display only works with select engines. Engine lower unit losses paint finish. Excessive gas consumption. Poor torque at take off. Dealers do not maintain certified Mercury mechanics.
