Which Style Engine Should I Use? An Aircraft Engine Or An Automotive Style Engine?

While Aircraft engines produce a Lot of low RPM torque they are very expensive to buy and maintain. An automotive engine when designed correctly can achieve the same torque and horsepower at a much more reasonable cost. Maintenance parts can be purchased at most automotive supply stores and the cost is considerably cheaper.

We have developed several extremely durable engine combinations that will Mmeet almost everyones needs. These engine combinations feature forged pistons, roller camshafts, specialty valve train components, additional oil capacity, Etc. That have been tested time and time again to ensure there durability will stand up to the job. Most airboat engine manufactures are still using old technology that just simply won’t last very long to keep cost down, When in the long run will cost you more money. The engine packages that are listed come standard with fuel injection. With todays fuel containing so many additives and ethanol, carburetors just don’t last very long. For those of you that think fuel injection is not right for your application, We can downgrade the engine package to come with a carburetor.

Proformance Unlimited airboat engines are currently used by law enforcement, airboat charter services, and even saw service in specialty categories like the winter olympics.
