Re: Prop question
You should post this question on the "Prop Forum". Before spending money on props you need to make sure that the engine is performing as it should. The best prop in the world will not compensate for an engine that is not tuned properly. Next the engine setup needs to be checked. The AV plate needs to be at least even with or and inch or so above the bottom of the boat. If that's correct, then look at props. If not, raise the engine on its mounts (we are not talking tilt & trim here). But -- prop selection is a compromise between hole-shot and top speed. Four blade props help hole shot but are not "generally" as fast as a quality three blade. Stainless steel is "generally" more efficient than aluminum. Low pitch props are good for hole shot but decreases top speed. Higher pitch provides more speed but results in poor hole shot. You need to make high speed, full throttle runs with an average load. Note the wide open throttle rpm and maximum speed. You want a prop that allows the engine to run at or very near the top of the manufacturers rpm range. If it is higher than that you are over reving and need to increase pitch. If rpm is lower than that you need to increase pitch. But don't spend money on props until you do all the other checks first.
