[C320-list] Normal Performance Limits?

[Monte B.]

The engine RPM is low but the speed is about right. Was the speed GPS
derived or from the knotmeter on the boat?

I had my boat on the water yesterday afternoon for likely the last sail of
the season. Although the wind was 15-20 knots on departure it had dropped to
near nil by the time the crew decided to head for home. To ensure we arrived
at the dock before dark I slowly pushed the throttle to maximum. On still
water this gave me revs at 2900, knots at 6.75 and plenty of black smoke. On
easing the throttle back to 2500 revs I was able to maintain 6 knots and
eliminate the smoke.

 

I have a Yanmar 3GM30, a clean bottom and a Kiwi prop. Is this approximately
normal?
