So here we go again. I have a Sea Ray Sundancer 280, about 32 foot overall. Its large and heavy, and still has factory v-6 4.3's. I was told if I bumped up to twin v-8s, my fuel consumption would go down (better gas milage) because they have to work less to get up on plane, keep on place, etc... now that makes sense except you also now have v-8s to power. Also, once your up on place you also have your momentum. They work less hard any way. What are my true benefits of upgrading?? Higher top end and cruising spped obviously. But I cruise from Virginia to South Carolina, and sometimes Florida. Fuel is going to be an issue. So my ending questions, with fuel consumption go up or down. How much of a top end/cruising speed difference can I expect. And yes, I would be re-doing the outdrives, not repropping. Thanks in advance everyone!!!<br /><br />Derek

Really convoluted logic, Derek, but common among big engine salesmen.<br /><br />As long as what you have will get you up on plane and keep you there bigger engines will only burn more fuel, whether you go faster or not.<br /><br />If you are concerned about fuel efficiency you want more efficient engines. . . EFI or turboDiesel, but big enough to reach plane and keep you there.

Thanks JB...plus I figured, this Sea Ray came factory w/ the 4.3's. I'm sure those engineers know a thing or two about what they're doin. LOL...
