454 BBC 530HP Airboat Engine

Starting at $10,500

When you are building or looking at re-powering your air boat low to mid range torque is what you want. Running on dry ground takes a lot of torque and power to make it happen (We have done just that). We here at Proformance Unlimited have tested many different engine combinations perfecting the perfect balance of torque and power to allow you to get the most out of your air boating experience. Designing this type of extreme duty engine goes well past just making good power and torque. We have developed several combinations that are extremely durable and will allow the user to enjoy his or her air boating experience with limited down time and maintenance.
