I am replacing my14/21 prop on my Volvo AQ225/275. I have a 15/21 to replace it with. What will this change as for as perfomance etc. on my '86 capri bowrider?
Thanx,
Dave
Assuming similar design I see little change.The fairly large diameter difference may result in an rpm reduction.If you were having venting(cavitation) problems it may help.I'd be interested to see your results.
