Very well then. I will stop being confused about torque, power and horsepower for the moment. It would probably be helpful to discuss the...
The issue is the RPM at which the power is delivered. Go ahead and hook up a lower RPM (2500-2800) diesel like a DD or B series Cummins to a...
Cummins Mercruiser will give you a 1 year or 400 hour warranty on their QSB 5.9/Bravo 2 package with an intermittent duty cycle commercial service...
The low RPM torque of that DD engine would probably destroy most any 'consumer class' (mercruiser, volvo, OMC) sterndrive in a short period of...
The explanation makes perfect sense. Thank you. I now understand why most surface designs are as they are. Is it possible to accurately predict...

I appreciate that 114 bhp @ 4800 would be for peak use only and that a continuous output of 50 bhp @ 3000 or so would better insure (but not...
I'm wondering if anyone makes a marinizing kit for the BMW M21 524TD engine. M21 2.4l inline six diesel engine based on m20 gasoline engine....
That's an awfully short boat to have a command bridge. If it was my boat, I would remove it............. Anyhow, if the transom and stringers are...
Sorry guys but this one is NOT a Fiberform. It's a K&C 22' or 25'. I can't really tell from the pictures what the length is. AFAIK, they...
The J-Class yachts that raced in the Americas Cup series during the late 1920s and the 1930's might qualify.
Finally, I've attached a Boat Magazine reprinted article which contains a sterndrive and inboard v-drive performance curves. From a review of the...
