Had a big problem on the lake yesterday...rope around the prop caused the engine to jerk and die. We have a 2005 Yamaha 115Hp on a Bennington 22ft. Pontoon boat. It bent the steering arm so the steering wheel would not turn. We were several miles from dock so got the arm bent back enough to get home. Just before getting there, the steering wheel would barely turn and then it was like a cable broke and there was not steering at all. Had to swim our pontoon about 200 yards. Please help with where to start. Thanks.
