Excalibur

Excalibur Propeller by WhirlWind – X-Core™ Composite Technology

For Direct Drive Applications

The Excalibur propeller features an all new high-performance blade design from Whirl Wind. The Excalibur Propeller design incorporates Whirl Wind’s exclusive structural X-Core™ Composite technology and the Whisper Tip™ blade style with its highly tapered profile and an aggressive swept-tip that offers superior performance.

The Excalibur blade is 5.5 wide, to bring the perfect performance that you are looking for. Now you don’t have to choose between Razor X’s unbeatable light-weight snap or the Whisper Tip’s renown low-end push. Now you can have it all without compromise with the Excalibur.

The Excalibur is available in 66” to 74” diameters, in 2, 3, 4 and 5 blade configurations. The Excalibur is an excellent upgrade for any Aircraft 4 Cyl or 6 Cyl powered airboat, as well as direct drive automotive powered airboats.

Excal-68_lowResAll 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.

    Just installed my new Excalibur propeller on my Cadillac direct drive, Pitch is set it at 8 degrees and turns 3100. Pulled off the hill easier than the 2 blade I had before. Cruise rpm was 150 less with the Excalibur and very quit too. Plus to four blade is just bad ass looking too. I will be riding again Sunday and will try it at 2800 and maybe 3200. I will update you. Needless to say I like this prop. Thanks.

    Engine: Direct Drive Cadillac

    I went for my first test ride today with the Excalibur, and I was very impressed. I bought the 66″ 3-blade for my 12×6’8 Thurman with an 0-320 and the verdict is, this is a great combo. Previously I ran a 66×34 woody and a 66″ 5-blade Warp Drive. I felt like the Excalibur improved the low-end-push and the mid-range, and the top speed between the Warp and Excalibur about the same (which is great!). The noise was much quieter with the Excalibur too.

    The biggest gain I noticed was in the mid-range. With the Excalibur I was riding a ‘fast cruise’ at about 1,900-2,000 RPM, whereas the ‘fast cruise’ with my warp was around 2,100-2,200 RPM. Cruise RPM with my woody was even higher than the warp. As far as low-end-push goes, the Excalibur got me up on plane with just a quick stab of the throttle. It runs smooth and the snap is definitely there too. Overall I’m very happy with it. The Excalibur does everything very well. It’s the best prop I’ve ever put on my boat.
