What you need to know about propellers.

One of the most important aspects of boat performance is the propeller. The Propeller PITCH must be correct for your boat to get up to it's full potential; no matter what size of engine or kind of boat.
Pitch is theoretical distance, in inches a propeller moves forward per one revolution. A 24-inch pitch prop should move forward 24 inches with each 360 degree turn @ 100% efficientcy.
Slippage is the amount of forward movement lost per revolution.

The goal in selecting prop pitch is to be able to run the engine at, or near manufacturer's recommended maximum RPM when at full throttle with a typical load in the boat, trimmed up for speed.
With to high of pitch (over propped) the engine won't reach maximum RPM, slow to get up on plane and have sluggish performance.
With to low of pitch (under propped) the boat will jump up on plane quickly (or worst case, spin the prop and over rev the engine while slowly coming up to plane), accelerates quickly, breaks the prop loose in turns, causing the engine to rev-up and slip the prop and at wide open throttle (WOT), exceed maximum RPM.
Neither condition is healthy for the engine, fuel economy and especially performance.
At WOT a increase or decrease of each inch of pitch is equal to 150-200 RPM; decrease pitch by one = increase in maximum RPM 150-200. Increase pitch by one = decrease in maximum RPM 150-200.
