[C320-list] Road Diesel vs Marine Diesel

[Jack McDonough]

Bob:

I know whereof you speak, having sat on a restaurant deck in Portsmouth and 
watched boats fighting that current. Yikes.

But, on the subject of speed, what RPMs do you run to get to 7.2 knots? 
Cruising at 2600, we get in the range of 5.5 to 6 knots.
