    Re: 86' Evinrude poor performance

    Don't assume anything at this point. I would go back and retest all the ignition parts.

    Re: Hydro Electric Shift

    Joe Reeves explanation is right on.
    If when in the water you are using the remote control to shift it in the water the problem is in the remote control. Most likely the shift switch.

    Re: Help with rd-25d motor?

    If you don't have one already buy an OMC Service manual for your motor. Much easier to fix things with it and a lot cheaper than trial and error.

    Re: 1965 40HP Evinrude starter flywheel issues

    There are a lot of those motors around so replacing it with a good power head shouldn't be too hard. You could also replace the crankshaft with a used one but with new gaskets, seals, etc. it could...

    If possible I'd take it back to the seller and get my money back. You're looking a a lot of money to tear the engine down and replace the crankshaft. I had one repaired once but it was not dinged...

    Unless you know the history of the water pump I would drop the lower unit and have a look at it. Also check the grommets.

  17. Re: Help with starting after replacing shift sw. Johnson 50ESL72C
