I recently installed a Westerbeke 64 with a 19X15 prop, this pushes my 40 in calm water to 6 to 6.5 knts at 1800 RPM.

5.2 knots at 2200 rpm?? That's pretty good. What size is your prop? how much fuel do you burn? I get 5.6 knots, but I have to turn 3200 rpm to get there. It is within the specs for the engine (4-107) but I don't like to wind a diesel that tight. I burn about a gallon an hour and have a 17 inch 11 pitch 3 bladed prop. I have always felt "underpropped", as I can easily push the engine faster than it is supposed to turn.
