Still scratch'n me noggin..

Prop is original size and pitch and clean, no barnacles.
Fresh water cooled engine, so no internal zincs.
Impeller is fresh, Just replaced by yours truley so I know at least this is right.
Only smokes a little when started after a week long layup, this has been improving since the marina in their infinite wisdom used EITHER to get her cranked to do my bottom job. ** I will no longer beat that dead horse}.
I believe we were doing about 6 kts at 3100 rpm and 5.3 kts at 2250 rpm.
70% = 2520 rpm, 80% = 2880 rpm, 86% = 3100 3100 = BAD???

So I'm still scratching my head on this one. Thank ya'll for the feedback. I'll get this figgered out if it kills me. Financially that is...

Fair Winds,
