    1971 Evinrude 50hp 50173S reverse, AGAIN

    I can only shift into Rev gear @ very very low RPMs, and if I increase speed while in rev gear...it will jump out of gear. I've been through this problem very recently in this forum.

    1971 Evinrude 50hp shift wires

    I'm having wiring issues with my '71 50hp. I picked it up for free because it was binding when turning over. Of course no start. Upon inspection, it turned out to be a fried lower crank bearing. Powerhead rebuild is done. Engine starts, and runs great (in forward). I've read ALOT of posts about...
