Straub Tech understands when the most important tool in your business doesn't run, you're not making any money. Airboat owners, whether guiding, moving supplies, or transporting people, need a reliable power package on their boat. Power and fuel economy are a very close second and third, but reliability comes first. You can get all three from Straub Technologies!

Our airboat packages are designed for a given engine size working in a given RPM range. Using mathematics, we have engineered the correct induction package to maximize the power throughout the power range. Our machining tolerances are based on durability without sacrificing power. Our clearances are set to maintain stability in the valvetrain and give 100+ hours of service. All the parts Straub Tech uses are from quality manufacturers. All machine-work and assembly is done in house by our cylinder head mechanics. The heads in these packages are matched with a camshaft designed by Chris Straub.
