Hello prop guru's
I just picked up a sea ray 197, 1978 model year 190hp merc 898 305 chevy V8. The boat came with an old well used and beat up stainless prop. I cant find any markings on it as to manufacturer or pitch. My question is, what prop would have come on this boat new as far as pitch goes? also, I intend to use this boat for trolling for salmon on lake Michigan so it will spend most of it's remaining life going 2.5MPH. I'm not looking for a ski or water sports prop. I'm looking for something that can get me 40MPH at 4000RPM. Any suggestions as to what pitch/diameter I should be looking for? I would like to go back to the aluminum prop for cost reasons. Is stainless a better bang for the buck?
