Marine diesel

[GradySailfish]

What kind of diesel do you want to put into what kind of boat. The lower end-powered diesels won't harm a Alpha sterndrive, but the upper end stuff is creates too much torque for a alpha and require a Bravo class drive.

Volvo makes the best drives although I'm not sure what series of drives can handle certain diesel power, but I'm inclined to say I prefer a volvo drive to a merc drive.

That said, my Grady White Sailfish has twin Cummins Mercruiser 1.7 DTI 120 HP a piece diesels mated to Alpha X drives. So far so good, but those drives are actually reinforced Alpha drives (they are called Alpha X drives)

Basically it is feasiable with great reliability, but you need to make sure the drive can handle the power.
