I have a 1990 150 H.P Force outboard. I was cruising on the river today and I felt a jerk and the engine quit. Had to use trolling motor for an hour to get back to the ramp. When I got the boat home I tried turning the prop and it wouldn't turn. I removed the prop and there was a bunch of fishing line stuck on the shaft. I cleared all of the line out, but the prop still turns very rough and the engine won't even try to crank. Does anyone have any suggestions? Any help would be greatly appreciated.
