I´m considering purchasing a Carver 530 with 475 hp Volvo TAMD 74 engines. Their max unloaded RPM is 2650 but both engines only reach 2200 under power
Hull is clean, props not damaged and Volvo engine surveyor says engines are in very good condition so i surmise the props have too much pitch.
I will only be travelling at 10 knots and about 1500 rpm for 95% of the time.
Question
1-Will the current props cause undue strain to the engine if I ran it at 2100 rpm for an hour a few times in the future?
2- Would fuel economy at 10 knots be better the way it is, or better with the props repitched to achieve 2650 rpm under power?
