Excalibur Propeller by WhirlWind – XCORE

For Direct Drive Applications

Excalibur Propeller incorporates Whirl Wind’s Whisper Tip™ technology with its highly tapered profile and an aggressive swept-tip that offers superior performance just like the wings on a fighter jet. This design decreases the propellers drag and noise, thus creating more thrust, and better fuel economy.

All WhirlWind blades are equipped with a long electroformed nickel leading edge that wraps around the tip end of the blade. Although nickel is much more expensive than other materials, WhirlWind uses Electro-formed Nickel because it is the toughest material available for leading edge protection. The blades are constructed with advanced thermo set aerospace graphite composite materials.

100% of WhirlWind airboat propellers are manufactured in-house. This ensures top quality parts, on-time delivery and quick product development.

Made in the USA.
