well heres the story. Last year i was given a boat by a buddy. It sank at his dock and he said if i got it out of there then I could have it, needless to say its now sitting in my backyard. Well after doing a little work to it, I got it running and decided it was time for the boat to go. Today I met a guy at the lake to take him for a ride, thinking it was a done deal. When I put it in the water it fired up just fine as usual, but it wouldnt go forwards or backwards. The engine would throttle up but I couldnt go anywhere. Yes the water was very cold as I swam the boat back to the boat ramp! Any thoughts on what would make this happen? It ran like a dream before I put it up for the winter. Its a 305v8 volvo penta on a 96 seaswirl 201 lx.
