I need help/advice please. I own a 24foot Daycruiser (Vintage Sunseeker Mexico 24). I fitted a new engine a few year ago (Volvo Penta 5.0 GXi). When complete I started the engine and it run well for a few minute and stopped. I then realized I had left the fuel valve on the off position. I turned it on and after a few tries the engine started ok. My question is that after using the boat for a few years I am not convinced that it delivering it max power. For a 280hp engine and a boat that weighs approx 5000lbs it should be nearing the 45knts mark. It has never gone over 34knts even with a clean hull.
I remember reading in the Engine Installation guide that it could damage the fuel pump if the engine is run with the fuel valve shut. The engine starts and accelerates smoothly it just that the speed/power is not there.
