Can prop pitch be changed?
Pitch Alterations Propeller pitch can be changed to a higher pitch (up) or a lower pitch by up to TWO degrees. Each 2° degree change in pitch represents approximately 300-400 RPM difference. Cupping the trailing edge on a propeller can also affect RPM – no cup to heavy cup can change the RPM’s by as much as 200 RPM.

Will a different prop make my boat faster?
Change Your Propeller If you are running an aluminum prop, changing to even a basic stainless steel prop will usually improve top speed. Because stainless steel is stronger than aluminum, the blades on a stainless prop can be thinner, which reduces drag in the water.
Does lower pitch prop increase speed?
A lower-pitch prop is like low gear in a car or a bicycle—you’ll accelerate quickly but top speed will suffer. A prop with too much pitch may deliver more top speed because the prop moves further forward with each rotation, but acceleration may be poor and the boat will struggle to get on plane.
Will a bigger prop mean more speed?
The lower the prop pitch, the better your hole-shot. However, this comes at a price: top speed. The lower pitch makes the engine reach maximum rpm at slower speeds. Conversely, a higher pitch will deliver greater top speeds, but slower acceleration.
Is a 19 pitch prop faster?
The 19″ prop will give you less of a hole shot but a higher top speed if the motor is strong enough to turn it in the recomended top RPM range.
