I have a 1986 CD28 Cruiser (no Flying Bridge) with a Volvo 165 HP Diesel.I Can only get 3100 RPM at Full throtle. Does anyone have any suggestions of how to reach the 3500RPM spec?
Thanks PA

Re: CD 28 power Cruiser. RPM Question
Three possibilities I can think of. Least likely would be the engine. Did it ever get up to 3500? If it did, maybe it needs service.Paul Anastassiadis wrote:

Check the throttle cable. Is it pulling the throttle on the engine fully open?
The usual culprit for low (or high) WOT RPM is improper selection of prop. Ask your local prop expert what size prop you should be using for the boat. Or you could try Michigan (not sure of the exact company name) - they are very helpful in figuring out the right prop for a boat.

I will check the throtle. Thanks for the advice.
