    1999 115hp Johnson runs sweet one minute and hopeless the next

    Water pump serviced and cooling circuit is good. We suspect stator, trigger, ECU but with absence of diagnostic equipment we are reluctant to throw money at this if we are wrong.

    1999 115hp Johnson runs sweet one minute and hopeless the next

    I have the above engine that starts from cold and flies around at 5000rpm for 40 mph for a while. Then I go to idle for a while to pick up a passenger and when I move the throttle to fast; it runs as if it only has one cylinder working. After a few attempts I idled up to the ramp and went home...

    Trim cover removal Force 50 1996

    I am looking to remove the trim cover assemble from below the cowling on my Force 50hp. I want to clean up the oil and grease and see if I can check the security of the power head bolts and maybe fix an exhaust leak on one side of the power head mounting. I did remove the long bolt at the front...

    Mercury Force 40 or 50HP

    In the absence of a serial number, how do I determine the difference between a 40HP and a 50 HP on a H050412SD [ELPT]. I know the carby is different in the jets but that is all I can find. The reason I ask is because I suspect my motor has the wrong engine cover fitted.

    Mystery shim on drive shaft

    Sure is. also near the pinion gear on the other end. I have not picked up the new shaft yet, so I have nothing to compare it with.

    Mystery shim on drive shaft

    That might be true if it was on the other side of the bearing where the seals are.

    Mystery shim on drive shaft

    Hello all. I was directed here by Andy Nasser from Crowley Marine as they could not provide me an answer. Ref:1996 Force Outboard 50 - H050412SD [ELPT]. Although this is a Force motor it has all Mercury parts. When I disassembled the lower unit and the drive shaft, I discovered a 0.060" ring on...
