Proper Prop for CD 28/Volvo MD7A
Recently had a lot of work done on the Volvo engine - starts fast and runs strong - but I max out at about 1600 rpm's - I would think it should go up to 2000 - 2500 rpm's - my first thought was prop pitch - so I am checking mine (diver) - wondering if folks know the proper pitch/prop (2 blade)? Thanks - Warren

Proper Prop
I'm just wondering.
Are you still using the same prop as you used before the engine work was done?
What was the top end RPMs before the engine work was done?
I assume that there is no appreciable marine growth on the prop or hull at this time.

engine RPM - Volvo MD7A
The prop is the same as prior to the work being done - I bought the boat in Jan - since I knew it had an overheating problem I did not run the engine north of 1100 RPM prior to the repairs - so I really do not know - have you had experience with the same model engine? If so, what have you experienced regarding RPM range?
