I know Indmar has deisel engines available, but I thought I would share the news that Mercruiser is now using Volkswagens Toureg V6,V8 diesel engines, the V8 can put out up to 350hp and 500 foot lbs or torque, comes standard
with fresh water cooling, weighs almost 800 lbs( great ballast for V drive boats). Fuel savings of up to 30%, top rpm 4200.Imagine the pulling power of this engine in a direct drive boat, out with the 454 and put in new V8 diesel* The down side is the cost, just like getting a diesel for your 3/4 ton truck, buck up the dough if you want the best.
Imagine one of these new V8 deisels in a older Saltaire that came with a big block** it would be a sweet boat
