So here in Pittsburgh the season is just starting and the river has been full of debris. Yesterday we smacked log moving pretty good and afterwards the boat/engine had a substantial vibration at idle. We putzed back to shore without throttling up because the vibration would just increase.

So the obvious things to check are the prop, shaft, and strut. Out of the water they all really appear to be in good shape. I know with the shaft a minor bend could be thought to see so I'll probably take it out and see how it rolls and maybe take to shop to get looked at.

The strange thing is that when going to put the boat in reverse the engine shuts off and when the boat is in neutral it seems it is a bit throttled up. Any ideas on what would have cause this issue after a big prop strike?

Boat is an 85 Sunsport do these have a kill switch or something that may be getting hit could this be transmission related? Or maybe something in the throttle mechanism?
