Hey I have a 1981 Evinrude 35hp outboard with controls and electric start that works GREAT except one thing that I cannot figure out
When I'm driving almost full throttle or full throttle the starter is bouncing up and hitting the bottom of the flywheel.
I have replaced the spring nut and spacer hopping that would be the easy fix but that did not work

Any other ideas what is causing this or what is the problem your info would be greatly appreciated

Thank

Start the motor and then undo the fuse, i think that fuse only isolates the starter circuit. Then go for another full throttle run and see if it happens again. If it doesnt you are getting a short somewhere in the starter circuit, possibly in the control box.

the "bendix" could have a weak or broken spring on it, the one that holds the starter gear down.

Can you explain more clearly?
Are you saying that the starter is spinning the bendix up into the flywheel, or ...when you go over a significant "bump" is there a "ping" as the bendix bounces up and off the flywheel?

Sorry when the motor hits high RPM's the bendix vibrates up and hits the bottom of the flywheel

Then I'd most definitely be looking at the spring as was suggested already.

Next possibility: Intermittent firing of the starter solenoid. Look for frayed or worn wires that could be triggering such a problem. See if you can disconnect the solenoid wire and rope start her. Does it still happen?
