    Carb. bowl gasket won't stay put...

    1986 50 horse... I am having a recurring problem with my carb bowl gaskets. They swell up from the alcohol in the fuel (I can't find fuel without it) and then they pop out of the groove and the bowl leaks. Any suggestions?

    oil leak, 1986 50 horse 4 cylinder...

    I've got unburned 2 stroke oil leaking out from under the flywheel. I thought it was the crank seal, I replaced that and I'm still getting a leak. What else should I check? As far as I can tell, all nuts and bolts are tight... Also, I'm getting a periodic surge at full throttle. I'm...

    Surging 50 HP

    I'm not sure exactly what motor I have, the case is from a 74, but I think the power head is an '86, based on the carbs. If it matters I'm running a jet lower unit. I've cleaned the carbs completely and had it running great at one time. A few weeks back, I hit the wake of another boat at...

    Sticking float? (1974 50HP 4 cyl Merc.)

    4 cylinder 50HP, no top end... Fuel pump??

    Hey all- I have a mid 70's 4 cylinder 50 hp Mercury. I'm not exactly sure what year it is because the power head was swapped at some point, the serial number below the tiller shows it to be a '74. I've got the motor idling reliably, but it will only run at top end if I pump the bulb. I'm...

    1978 Evinrude shift linkage, stalling

    First post, might as well just jump into it! I've got a 1978 Evinrude 55 HP. It is set up with a remote (console). The nylon fitting that attatches the shift cable to the shift lever in the engine cowling broke. What is the name of this part, and do I need to buy the whole cable or can I...
