Dear WhirlWind, thank you for the excellent customer service. Your team went above and beyond the call of duty to get our propeller to us overnight, even with shipping delays beyond your control. Many thanks for getting us a top quality propeller in time for getting out on the lake and filling some gator tags. The Whisper Tip 2.0 blades worked flawlessly.

Dear WhirlWind, Just and update for you since I last talked to you about options for my 520 gitsu powered airboat. I have tried several different types and brands of props, and I put on the 74” 2-blade Whisper Tip wide blade and it is a great prop! I picked up a tremendous amount of push as well as top end, just wanted to let you know I think you have a great product. I used to be a hard core [brand X] guy but this prop has changed my mind.

I started the prop out at your suggested 18 degrees, it wound out at 2900 very quickly. WOW, THEN DOUBLE WOW WOW. YOUR SUPER SNAPPER PROP MADE AN IMPRESSION ON ME I WILL NEVER FORGET. 2900 RPM the boat literally leaps on plain. And cruising at 1800 RPM tp 2900 RPM is like I opened Nitrous, That was just testing my settings. I don’t usually drive like that, I can cruise at around 21 to 2200 RPM and not have oil and cylinder heads heating up much. I have aircraft gages for them, and am always watching my temps. I couldn’t cruise with the warp drive at those 2 RPM’s without having to back down to let the 2 temps cool down. I think I am now getting more air pulled over the engine cylinder heads, and that is keeping things cool. Response and handling is totally different now everything is quicker. I am VERY PLEASED AND IMPRESSED. YOU HAVE A GREAT PROP THAT IS FOR SURE. FROM NOW ON WHEN ANYONE ASKS ME WHAT PROP TO BUY, MY RESPONSE WILL BE TRY WHIRLWIND, GIVE THEM A CALL BEFORE YOU CONSIDER ANYONE ELSE. YOU NOT ONLY SOLD ME THE PROP, YOU SOLD ME ON YOUR QUALITY AND CRAFTSMANSHIP. I ALREADY E-MAILED FARON (at American Airboats) MY PLEASURE IN ORDERING AND SUGGESTING YOUR PROP. HE SAID I WOULD BE HAPPY WITH IT, THAT WAS A MILD UNDERSTATEMENT, TO SAY THE LEAST. ONE VERY SATISFIED CUSTOMER.

I would like to start by saying “Thanks again” for all the help last year in selecting a propeller for my particular application. The engine assembly is a TSIO-520-E. Since these photos were taken, I have installed a new Turbonetics turbocharger. With slight engine work and 18psi of boost, the engine dyno’ed at almost 375hp. (300hp stock) At our elevation of4500 feet, the AB-300, and at 2850rpm the boat clips along at over 72mph. I have to give most the credit to the propeller and you folks at Whirl Wind. Everyone that comes in contact with boat is quite impressed with prop and all other workings!

Patti, Thanks so much for helping me with the direct drive blade upgrade. The Whisper Tip Blades are perfect, and the boat performs absolutely amazing! I will absolutely tell everyone in need of Blades to contact Whirl Wind Propellers.

Thanks for your help with my new prop. It arrived on time in good condition and has improved the performance of my airboat by probably 30% and also reduced noise levels by about the same
Very Happy!

New Trend – 5-blade 72” Excalibur on 6-Cyl Aircraft Engines
Lower Cruise RPM, Better Fuel Economy, and Runs the Hill better than your buddies… No Compromise.

This prop setup really blew me away across the board any and every aspect of performance. Just wanted to say thanks and great job probably best aircraft prop on the market.

Propeller: Excalibur 72″ 4-blade
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.

So far so good. Set it at 8 degrees and turns 3100 . Pulled off the hill easier than the 2 blade whisper tip. Cruise rpm was 150 less with the Excalibur. I’m impressed so far. Only got a 20 min ride in. A lot of personal issues over thanksgiving. I will be riding again sunday and will try it at 2800 and maybe 3200. I will update you. I think I like this prop a lot. Thanks.

I have been airboating since the 1970′s and have run Sensenich propellers on strictly nothing but aircraft motors, from 4-cylinder to 7-cylinder radial engines. Then I changed to Water Walker and have run Water Walker until now.
I got the 4-blade Excalibur from you a few weeks ago, and this prop is it! Bad Ass! Low-end push is excellent, and it has the pep. Everything you need, low, medium, high. Pushing a 15 ft River Master, 520 Continental fuel injected aircraft motor, average RPM with this prop is in the 2,800 RPM range. Plenty of power. Overall nothing to compares to the Excalibur, I highly recommend it.

Thank you for both the propellers you sent me – both the SD & SP blades work great! I am very very happy with your props and my friends all like them too! I know I’ll be calling with more orders, so keep up the good work!

I have been running your Whirl Wind AB400 propeller now for several months on my airboat. The 4 blade 82″ Stump Puller on a Lycoming GSO540 upstack. I must say that I have tried others in the mean time, and this propeller is simply the best hands down. It is quieter for starters. Not near as much vibration as we all know that some other props have.
But the main thing is the performance that it offers. Much snappier!! Lets you feel the G forces when accelerating!! Tons of push!! Makes hill climbing a snap.
Yes, I have tried all the others. Since I built this boat myself I wanted to find the best performing propeller on the market and without a doubt the Whirl Wind SP prop has been the best performing prop that I have found in all aspects.
Thank you so much for an awesome product!!!”
Tyler C.
Dear Patti, Congratulations!! What great products Whirl Wind Propellers offer! The Stump Puller is the best, you all should be proud of your developments. We have a new power plant, the BEST propeller and an enthusiastic support, what a team. Thank you so much for you and your teams support.
