I should add to my answer to cover some of the issues about engine modification the OP had. The short answer is: no. Going slower is the best way to increase mileage. The 450HP version of that engine is about as efficient as it can get. There is no magic bullet that generates the horsepower needed to move the boat a certain speed with less fuel. Make sure you have someone very experienced in the Detroit 2 stroke engines do a complete survey before you buy; this will be someone separate from the hull survey. You can get DD surveyor recs here, at HOF and at, which I'd advise subscribing to. Is this boat in Tortola?
