![]() 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.

The Volvo website says that their DPS and XDP drives are designed to mate to high power diesels up to 225hp and their larger DPH & DPR drive mates to diesels in the 225-350 hp ranges.
For a Mercruiser you would need either the Bravo 2 or 3 models to take the higher torque of the larger diesels, the Alpha should be able to handle the lower hp models.

Gradysailfish. Do you have a 25' grady? Was it an i/o new or did you do a convert? What is your cruise mph/burn and top speed? I have heard those 120's burn next to nothing but vibrate pretty badly. I saw the motor drive combo quoted for about 11 grand.
I am guessing your burn combined about 7.5gph at 25mph. Am i in the ball park?

For the question of different outdrives....I know the Bravo I has a different top cap for diesels....it has cooling fins on it. There could be different internal parts as well.
