Does anyone know how to stay the same rpm range when going from a 3 blade to a 4 blade??
I have a 15" 19 pitch Stainless Rebel(evinrude)prop now and would like to try a 4 blade stainless for some transom lift and bite.
Any educated guesses on what size to go to??
I do not want to buy a couple props--they ain't not cheap!!
