Props - RPM's and Cruising Speed
I definitely agree that the boat is overpropped and you could be causing
significant damage due to detonation from overloading the engine. Playing with the secondary opening adjustment also sounds like trouble just waiting to happen due to possibly running the motor too lean. You need to speak to an experienced propellor shop about your options. Also, a convertion to an efi setup although costily might help you burn less fuel at that higher RPMS that you apparently need to achieve a desireable cruising speed. You would also reduce engine noise from the secondaries opening with the efi setup. Jay |
