I am going to repower my jet boat for next year. I have a 20ft Wooldridge extra plus with a 351 and a Hamilton 773 right now. I am familiar with the 350 and can easily swap motors and upgrade to fuel injection. I am over the Ford marine motors, parts are getting hard to find. We were talking on our long boat ride on the yukon and talking about diesel motors. They are built for long running with lots of torque to haul heavy loads. Just the ticket for the Yukon. We thought the draw back would be the hole shot and top end speed maybe. The other draw back may be field maintenance, but we were not sure if it would be better or worse than the 350. Oh yea, and the price. Does anybody have an opinion on diesel vs gas that could give some insights on performance, maintenance and cost effectiveness? I emailed FNM Alaska and they said that their 250 HP model will give similar performance to the MPI 350 with 3 gal per hour fuel savings.
