I was out this weekend and when I had te throttle wide open with the boat loaded the engine would rev up but no more power was felt on the boat. I would let off the throttle and things went back to normal. It felt just like when your clutch goes out on a car and you give it the gas but the plates just spin and no power is felt.

What could this be? I didn t hear any strange noises other than the engine revving without any stronger forward propulsion. Thanks!!!!

Spun hub in prop. Classic symptoms.
