All modern diesels ranging from the Volvo D3, Yanmr BYs, Cummins QSB/C, Volvo D9, Cat Acerta, etc all make about 20 hp per gallon per hour of fuel burned at maximum hp at WOT.
Great, but most operate WAY below WOT and there the diesel falls flat.
For anyone contemplating a gas engine simply look up the cost of a brand new "crate engine" from the mfg of the boats engine.
You may find a new gas engine costs less than a simple rework of the injectors on a diesel.
The old Ford Lemamn Econo Power injectors are mechanical and really cheap to do, but a modern electronic injector can be a $1000 each! and just the brain box more than a new Crusader, complete.
At 200 hours a year , even if only normal PM is required , with gas at $3.13 and diesel at $3.90 , there will not be much "saving" from a diesel.
