Hi all, I have a pair of KAD44’s in a 32 foot sports cruiser and have different gear ratios to factory spec (1.95:1 vs the factory 1.68:1) therefore my props are turning slower for a given engine RPM.
I’m running (incorrectly I know) Michigan A7 props which are giving me about 26 knots cruise at 3000 RPM and 34 knots at WOT (3800 rpm).
It feels slightly under propped and I have some mild vibration around 2000 rpm following a tangled fishing net incident therefore I think I have a bent prop and its a good time to consider moving to the recommend stainless C series if I’m going to replace damaged props potentially.
My question is: would a C7 prop set give me a little more pitch compared to the A7 Alloy versions?
