When the power-to-weight ratio of the diesel engine gets closer to gas engines, it will make more sense to have a diesel powerplant than a gasser. Not having an ignition system makes the diesel more reliable. (No spark plugs, plug wires, coils, distributors, crank pick-ups, etc.)
The diesel engines that make gobs of horsepower are VERY expensive. |

The only problem is the diesel motor will need something between it and the prop to make it a performance boat motor. Wont you give up something by having a prop so steep that will turn you respectable MPH's at a WOT of only 3200 rpms? Thus the need for multi speed gear boxes? I would think the massive torque of a diesel motor would allow this without a sweat.
Been a few threads on this...I wish someone would make one.. As to the diesels that make gobs of HP/Torque they are way to heavy for our type's of applications. Unfortunately, you can not have high rpms especially in a straight 6 application and expect it to last. Banks is suppose to be coming out with something shortly with over 600 hp..I will wait and see. |

Thank you all for your advices

Back in the old days, (when I was racing), SeaTek had an aluminum alloy diesel that had a great power-to-weight ratio and made over 600hp. The problem was it was over $100,000 back then. Today they are probably 800Hp and $250,000!
