I have a 1988 spl and I was about 10' from the ramp and I put it in reverse to get out of the way of someone and the motor shut right off. Well come to find out when I went to look for the bow line it was under water. I lifted the motor out to find the other end of the bow rope around the prop. How ever In forward the prop doesn't turn but has play back and forth. When I try to put it in reverse it seems to bind up and not shift into gear, and the prop turn all the way around both ways. Anyone know what I need to fix to get to work again. Did I break and shear pin?
