Airboats are flat-bottomed vessels that are propelled using an aircraft propeller. Also known as fanboats, these types of boats are powered using an automotive engine or an aircraft engine. One of the main draws of riding an airboat is its speed. However, it can be quite difficult to get the airboat to a speed that you like. There are several tips that you can follow to increase the horsepower of an airboat.
1. Use a Reduction Drive
One of the best ways to increase the horsepower in your airboat is to use a reduction drive. It is advisable to use a 2:1 belt-drive reduction on airboats if you want to increase the horsepower.
2. Install a Cam
Another great way to increase the horsepower is to install a cam. This will improve the low-end performance of your airboat. It will give you higher torque with lower rpms.
3. Use a High Thrust Propeller
The propeller of airboats is generally where most of its horsepower comes from. In this regard, it is advisable to install a propeller that is specifically designed to provide a higher thrust at a lower rpm.
4. Use a Propelling Engine
You may also opt to change the engine of your airboats. Replace the engine of your airboat with one that is designed to turn a propeller like an aircraft engine. These engines are great because they can produce high torque, at much lower revolutions.
