I have a 2000 Predator with a 454 in it. My last trip out i had to jump my electric fuel pump for it to work again. The boat ran good after that but then the next day out on the water it would only idle and would die out when accelerating. There was gas left in it durning the winter and i topped it off with new gas and ran almost a half a tank of it through the first day. Does anybody know what this problem could be?
