Hi - I am having the same problem with my 2002 Utopia 205 boat. It was running fine the first day of the summer and then the second day on the way back in it started shutting off. Cranks right back up - start going - shuts off again. It will idle OK and starts right up - but just want run without shutting off intermittently. Did you have any luck with your attempts to fix your boat?
Thanks - David
David I am waiting on the new fuel filter from Merc. It shipped yesterday. When it arrives I will take the 7feet of fule hose I bought and stick it into a fresh 5 gal can of gas and see how it goes.
I will post my findings.
