2375 RCW Merc 150 .SPS 200
1st prop was 15 X 15 Mercury Enertia . 5200 RPM 34 mph.
Today they tried a 15.3 X 14 Enertia 5400 RPM 31 mph .
Service rep said we should drop down an inch . I didn't ask, diameter or pitch .( didn't think of it at the time )
According to the Merc site I should be at 5800 rpm ,38- 40 mph
Suggestions please .
Thanks
