The Whisper Tip™ is a swept-tip wide blade that offers superior performance by increasing the critical Mach speed of the propeller tip. This increased Mach tip speed decreases the propeller drag and noise, thus creating more performance and less noise. Just like a wing on a jet aircraft, this phenomena is amplified with high RPM engine/propeller combinations such as direct drive auto and aircraft engines.
So what does this mean for your airboat? The Whisper Tip™ will give you the most push and lowest noise possible.
AB-200 configurations are available with standard aluminum hubs, and the optional black engraved hubs. (Click image to enlarge)
Specifications
 The Whisper Tip™ is equipped with a 24.5" long nickel leading edge that wraps around the tip, and the blade is constructed with advanced aerospace composite materials. This propeller has been designed to operate in RPM ranges from 2700 up to a maximum of 3000, with horsepower ranging from 220 up to 300.
Whirl Wind's Whisper Tip™ Series of airboat propellers was specifically designed for direct drive aircraft and automotive engines. The two blade Whisper Tip™ is the perfect prop for most 220 to 300 hp a/c and direct drive auto engines. The two blade Whisper Tip™ has become a fast favorite for the Lycoming 540 engines!
The Whisper Tip™ available in 69" - 74" diameters.
