Hello, i need an opinion on a stainless prop. What i have now is a solas 17" pitch 14.8 al 3 blade prop.
I want to switch to a 4 blade stainless and heres what im thinking. I cant reach my redline of 5500rpm
I have a 1988 chaparral 2300 with a cobra drive. I have a carberated 98 vortec truck engine. It makes about 250hp i would guess.
Right now with a light load it will run 4700rpm and 49mph. I want to increase the rpm by 500 or so.
The boat is big and heavy but is doing ok with a light load. Im looking at a 14.5"x16p 4 blade stainless prop. My question is should i spend my money on a 15" or 16" pitch 4 blade. I need the stern lift of a 4 blade and i honestly think the aluminum prop i have now is flexing. Thoughts please?
