OK I am old and forgetful so be easy on me!
I am looking for info on what effects prop diameter has on RPM?
I have used Mercruisers Prop Calculator and it states that I need a 15 or 16 inch diameter prop with a 15,16 or 17 inch pitch!
I have the paperwork from the original owner and it states that a 14.5X17p prop was delivered on that boat, 1995 2400SCR 5.7l Alpha 1 Gen 2 with 1.47 ratio!
It is now running a 14.5X19p and as expected it wont reach max RPM!
Looking for some useful feedback from any and all who have knowlege!
Thanks from an old forgetful boater!
