Really? I cruise at 1900-2000 rpm at 6 to 6.5 knots. I can get the engine up to 2400 rpm, but by that point it's trying to climb out of the water. At 1900 rpm it's burning about 3/4 gallon per hour. At 2200, it's burning nearly 2 gal/hr. Since the gain in speed of at most a knot isn't worth it, I just cruise right along.
What are your experiences with speed/rpm/fuel consumption?

I repitched mine from a 13 to a 12. Mainly because I
thought I should have more engine RPM's before the
engine started to bellow black smoke. I have a W58 and
now can get it past 2800 rpms. Not that I ever run it
that high, mostly cruise at 22 to 2400.

Hope you had a good trip back from Bellingham! I
have been looking into the prop pull on Syringa as
you know. (This is when the vessel is under steady
steaming in forward at 1800 rpm or above) (not
backing or docking) I don't believe the shaft is
off set (if it is it's not much) and should not
account for that much pull. The prop may be over
pitched. I will let you know if or when I come up
with the answer.I would like to hear from anyone who has changed
propellers or reduced the pitch.Thanks
Don
