Propeller Characteristics - Performance
How does pitch and slip affect performance?
Slip is the difference between actual and theoretical travel of the propeller blades through water.
High slippage means that the boat is moving less distance for each rotation. This typically happens with boat props that are poorly matched.
A correct fit will move forward about 80 to 90 percent of the theoretical pitch.
