The highest RPM for my 96 2400 SCR is currently 4800. That is pretty low for the 5.7 liter engine.

Actually that rpm is exactly correct for the 5.7 in a marine application.

Actually I think you are right in the max RPM for that engine. I have a 95 2400 with a 5.7 A1G2 4 barrel carb and it has a wide open RPM of 4800.
It came new with a 14.5x 17 prop.
I am running a 14.5x17 now and my max RPM is 4500, I have only had it there a couple of times as my wife and I like to keep the speed down and enjoy the ride.
