I see quite a few postings with no reverse, but nothing with no forward. Took the boat out for a couple of hours the other night and everything worked fine as usual, we came home and docked it using neutral, reverse and forward to get it in position with no problem. Last night we hopped in the boat, started it up, untied it and put it in forward to pull away from the dock and nothing. The engine started to rev as I pushed the lever ahead, but no gear engaged. Pull the lever back and it slips into reverse with no problem, ahead just results in neutral and revving the engine. Any Clues?
