View Full Version : Sputters and loses power at 15mph or more

Boat ran great last season. Last fall did the 100hr service at dealer and had them winterize the boat. Heated indoor storage for 5 months. De-winterization at the dealership. Went out this morning and the engine had a severe sputter and loss of power when I put the throttle down or tried to go above 15mph. Any Ideas on what is going on with my 1995 fuel injected prostar?
