|Selecting the right boat propeller is an important factor in maximizing your boat’s performance. Determining the correct size and style of boat prop
will keep the engine operating within its recommended rpm range and allow it to apply its maximum horsepower to the water.
|Not All Props Are The Same!
|Size — Prop size is described by referring to diameter and pitch. Diameter is twice the distance from the center
of the hub to the tip of any blade. Generally smaller diameter props correspond with smaller engines and boats, while larger diameter props correspond
with larger boats. Pitch is the forward movement of a boat propeller through one complete revolution measured in inches. Lowering prop pitch will increase
acceleration and pulling power. A higher pitch prop will make a boat go faster as long as the engine has enough power to keep the rpms in the optimum
range. If the engine doesn't produce enough power to run a higher pitch prop all performance suffers and engine damage can result. So - select the prop
size that lets your engine operate at WOT within its correct rpm range.
Number of Blades — When the number of blades are changed, diameter and pitch may require a minimal adjustment to keep the RPMs in the proper range. For most purposes, 3 and 4-blade boat propellers can be used interchangeably on outboards and sterndrives without much of a change in performance
Material — We offer propellers made of composite, aluminum, and stainless steel. Composite boat props offer good performance, are durable, and inexpensive. They also offer some protection for your lower unit during a prop strike. Aluminum props are the most common and are suitable for the widest range of applications since there are so many models and styles available. Stainless steel props offer the highest performance and best durability.
Cupped Boat Propellers — Special curved trailing edges enable the prop to maintain performance at highertrim levels
and in tight corners. Cupped boat props allow most boats to achieve a higher top-end speed or at least the same speed at a lower engine
RPM. They also promote more efficient fuel consumption.
What’s New With Boat Propellers? Modular boat propellers are becoming increasingly popular. In fact many engine manufacturers are now selling modular boat props as original equipment. Our current offering of modular boat props includes Michigan Wheel XHS Boat Propellers in both Vortex Aluminum and Apollo Stainless Steel.
How To Order A Modular Prop
Different boat propellers for different applications
If you regularly run your boat at different altitudes, you know the importance of using boat props with a different pitch to match your engine performance.
Maybe you have several different uses for your boat weekend cruising, wakeboarding, fishing, etc. Having two props pitched 2" apart lets you
optimize the power of your engine. Modular props allow you to save money on that second boat propeller.
