Fr Frank, I have a Mercruiser TRS drive so it uses the regular Merc V6 prop. My Rpm’s are right where I want them which is 4900-4950. I want to keep the RPM under 5000 as this engine has the cast crank and non forged pistons however with the cam that is in it, it would love to run up to 5200-5500 it's just the bottom end wouldn't like it. I can trim it slightly then the boats starts to porpoise and the more you trim the more it porpoises so I stop trimming when it just starts to porpoise. I'm wanting something to give me more stern lift, the revolution four was recommended on offshoreonly.com
