I have been struggling with this problem for a long while of the motor running too rich and blowing black smoke. 2 summers ago my LSV started running very rich and blowing black smoke after pulling a wake boarder. So performed tune up with plugs, plug wires, cap rotor, and the motor only ran worse. I just about had it and was going to take it to a dealer but I decided to buy a fuel pressure gauge. Started boat and gauge pinged to the limit of 100psi. Well looks like the pressure regulator went bad. Dealers and online retailers wanted $95 and up. I found the same pressure regulator was used in 1997 and 1998 Corvette. $55 dollars later and she is purring like a kitten on the trailer. Hope to water test this week.
