Hi all....
Don't know what happened, but I had pretty much beat up my 14x19 3 blade aluminum prop on my 20' Sea Ray, 5L Mercruiser and decided it was time to buy a new one.
Now, with the beat up one at WOT I was averaging right around 4600 RPM, midrange for the recommended RPM's for the engine.
Bought an exact replacement and RPMs jumped to 4900-5000 RPM @ WOT!
Can anyone maybe enlighten me to what/why THAT happened?
Another question, I had a chance to buy a SS prop, 15 1/4x 19, same pitch, larger diameter, very nice shape with no dings or anything for $100.00 and I bought it, anybody have any idea what this will do on my boat? Drop RPM's? Drop top end?
