muskiechaser Posted June 22, 2009 Share Posted June 22, 2009 I have both a stainless and aluminum prop for my 75 HP Merc.I just switched from the alum to stainless, and the engagement seems much harder with the stainless steel prop. I assume this is normal, the SS prop is heavier, but it seems a bit much to me. Am I going to shorten the life of anything in the lower unit with the stainless prop? I do get better performance out of the stainless, but ultimately I don't really need it. A couple mph isn't going to make or break my day on the water.Thanks,John Quote Link to comment Share on other sites More sharing options...
boatfixer Posted June 22, 2009 Share Posted June 22, 2009 You should feel more when it goes in, yes, but what are you idleing at for rpms in neutral? should be 900-1000 Quote Link to comment Share on other sites More sharing options...
muskiechaser Posted June 22, 2009 Author Share Posted June 22, 2009 I'm idling @ 700-750 RPM. It's an EFI four-stroke.Maybe I'm just a little paranoid. Quote Link to comment Share on other sites More sharing options...
