Having a intermittant beeper going off about 5600-5700 RPM. Is this a prop issue or engine ht. I talked to the Mech. and he want to hook it up to the computer but hes thinking it might need to lower the engine ht. I still have plenty of throotle left in her . Im running a old 25p trophy off the old motor and it was a 200efi. We never messed with the engine ht as of yet
