    1981 Evinrude 35hp question.

    The detent balls on the propeller shaft hold the shift dog in neutral. If you look at my picture thumbnail 22 and 4b that detent holds all gears. Not sure if you would have the same setup

    1981 Evinrude 35hp question.

    If you look at the pics I posted you can see the throttle cant to go to far in netural and reverse with my setup. Dont see anything in your pics that would keep your engine from being shifted at to high a rpm

    1981 Evinrude 35hp question.

    If it is at all posable to shift into gear or from forward to reverse at to high a rpm. dont do it. very dangerous to you and your engine.
