VEEM propellers are 100 CNC machined to hair thickness accuracy over every square inch of the propeller including the boss and high BAR overlapping blade propellers.

High speed boat propeller. They are engine RPM prop gear ratio normally for 15 to 30 prop pitch the distance that a propeller would move forward in one revolution prop slip the efficiency of the prop lower at high speed but perhaps very inefficient at low speed and the boat speed in mph. FORMULA TO CALCULATE THEORETICAL BOAT SPEED If you have the following information you can calculate the efficiency of your propeller and boat. As a professional supplier of marine propeller we can provide many other propellers.

At 80 MPH with about 6 prop slip you would be turning a 12x15 3 blade 5991 RPM. Less wear and tear on engine systems. 45 MPH The Gear Ratio between the engine and the prop shaft.

The same propeller can not achieve both the highest top speed and the maximum acceleration. The lower the prop pitch the better your hole-shot. Think of a propeller as you would a cars axle ratio.

Fixed-pitch outboard and sterndrive 3-blade. High-speed raceboat propeller design. How High Altitude Will Affect Propeller Performance.

Superior handling in tight turns and better overall maneuverability. As it has been pointed out many times the most appropriate pitch is the one that matches to the use of the boat and also enables our engine to reach at least the middle of the WOT rpm range recommended by the. Significantly reduced vibration and noise.

This is because air has less oxygen at higher elevations resulting in reduced performance. Prop pitch explained. Planes at a lower RPM.
