How does a gearbox work on airboat?

Airboats do not have transmissions but they can have reduction drives so you can run in the automotive equivalent of 2nd gear rather than 4th gear. So, one can decide to run in 4th gear or 2nd gear. To increase the effective power, a reduction gear is used so the prop spins at a lower speed than the crank shaft.

What does reduction gear do on a boat?

By slowing down the propeller we minimizes slippage (waste) which makes the whole power plant more efficient. Reduction gears are rather simple, one small gear, driven by the engine, driving a large gear which is connected to the propeller shaft.

How fast does the average airboat go?

Airboats are very fast compared to comparably-sized motorboats: commercial airboats generally sail at speeds of around 35 miles per hour (30 kn) and modified airboats can go as fast as 135 miles per hour (117 kn).

How much gas does an airboat use?

How do airboats do on gas mileage? Airboats do consume a lot of fuel, simply because of their engines and the amount of power required to propel the fan. The average airboat gets about two miles per gallon. For reference, most other boats get between 3 and 6 miles to the gallon or use about 20-30 gallons per hour.

What is the point of gear reduction?

The main purpose of a gear reducer is to alter the output speed of the motor in relation to its torque. For instance, if you need a decrease in torque but an increase in motor speed, the gear reducer will do that for you. Most gear reducers are intended to slow down the speed and transfer it throughout the engine.

How can I make my airboat quieter?

The best way to quiet an airboat is to take a holistic approach. Rather than focusing on reducing the noise from just one area of the boat target different areas, and by making even small noise reductions in multiple parts you will greatly reduce the overall noise created by your airboat.
