Hans-Erik:
We have the same engine.....our 32 has a fixed 2 blade prop (Michigan)
.......from your numbers provided, your boat is not performing the same
as ours. I can 't be precise, but our boat is approx. 1 knot faster at
the rpm's you mentioned (GPS speed, not Signet knot meter).
What's the condition of the bottom of your boat?

I've recently purchased a 1980 C&C 32 with a yanmar 2GM20F 18 hp diesel. We're
having some propeller/power issues, and I'm wondering if anyone here would have
idea of what the approx. cruising/max speed should be for this boat and engine.
I'getting 5.9 kts at full throttle (3400 rpm) and 5.3 kts knots at 2800 rpm. Is
this reasonable, or cause for concern?
Thanks!
