OK, so you do have a lightweight hull. It will really help to know just what RPM the engine turns up with your standard 13" prop before trying others. This engine does not have a rev limiter, so you will get a true reading. Optimal WOT RPM for this engine is between 5000 and 5500. The four blade props will help get the boat on plane if it struggles to do so, but I’m "guessing" you will see the best all around performance with the conventional 15" three blade prop. The 14" four blade prop will probably be best if you plan to pull skiers/tubers.
Needless to say, propping is far from an exact science. So, let’s get a true WOT RPM reading with your current 13" prop, and go from there.
What type of tach will you be using? Is it a dash mounted tach that is wired up to the engine? If so, please remember that this small charging system is unique in terms of tach settings. The OMC dash mounted tachs get set to position "5". Read the directions provided with aftermarket dash mounted tachs….
