How do I know what size propeller I need?

How do I know what size propeller I need?

Propeller size is expressed with two numbers, diameter and pitch, with diameter always stated first. Diameter is two times the distance from the center of the hub to the tip of any blade. Smaller prop diameters generally go with smaller engines, or with fast high performing boats.

What pitch prop do I need for 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.

What’s the difference between a 3 blade prop and a 4 blade prop on a boat?

3 or 4 Blades? A 3 blade propeller usually offers top speed performance while a 4 blade propeller provides maximum thrust and smooth cruising operation. Four blades have some features of their own, though. They often provide more lift at the stern which will help accelerate the hull, especially if it is stern heavy.

What RPM do boat propellers spin at?

Ideally a motor with a WOT range of 5000-5800 RPM (as noted on the boat tachomter) will reach 5400 rpm with the boat running wide open and trimmed out for optimal performance, with a full load of fuel and water and an average passenger load.
