Uh, ever heard of diesel?

Diesel? What's that?

[/kidding]

Yeah, I'd thought of it and ruled it out. This guy isn't going to switch out his twin gas motors for diesels, not unless he's in the charter business and can make it pay.

And even if he did, the price per gallon for diesel is even higher than what you pay for the ethanol-adulterated scooter juice they sell at the gas stations. You'd do better to run the thing on No. 2 heating oil, if you could get it to the boat.

Sure. I understand completely.

Depends upon the size and type of boat.

It it has sails, or is a displacement type, then diesel is a good choice.

Go fast, or deep sea fishing type boats need gasoline.

Of course, you can go the turbine route and use jet A...

Everyone NEEDS a $700,000 engine on their boat, don't ya think?

Happy boating!

You are wise to not switch gas over to diesel engines. The cost would be phenomenal. For one, diesels run at much lower RPM and would require a geared converter to get the desired prop RPM. There are some Hydrojet drives out there that are designed for Diesels, (Tractorjet, etc,) but they are very expensive and are mostly designed for pulling, not speed.

Diesels would get better fuel economy than Gas, but the cost would offset the gain quickly.
