Question:	Why are your propellers and blades prices so much less the other composite airboat propellers currently on the market?
Answer:	We get this question a lot. There many reasons, but the main reason is we are very efficient at what we do. The efficiency stems from intelligent engineering, state-of-the-art tooling and continually refining the process. We manufacture 100% of the propellers in-house with no outsourcing of parts.
Question:	Will more propeller RPM always give me more performance?
Answer:	Keeping the propeller RPM as low as practical will always lower the noise of the propeller. Whirl Wind does have propellers blades specifically designed for low noise operation, check with us for your application.
Question:	What should I do to keep the propeller noise as low as possible?
Answer:	No. All propellers have a maximum RPM for maximum efficiency (thrust). This max rpm is always dependant on propeller diameter. More prop RPM will not give you more performance like you might think. Sure it makes a lot more noise, but you're not getting anything for it. No appreciable performance gain More noise (dB) Shorter propeller life due to increased impact damage More wear on your engine Increased fuel burn Check with Whirl Wind Propellers for the right propeller for your airboat.
