im running the mercury 2.4. and im setting at 3 1/4 bp. If i trim the motor down a little the rooster tail comes down but im only running at 57mph with the 25 trophy. Should i get a 24 tempest. I tried a 25 tempest and i lost speed and rpms. boat doesnt have much lift. I was told that i needed to run the 25 trophy at 4" bp. That doesnt make much since to me. i havent tried it yet.
