Welcome to Century Drive Systems, Inc.

Building Airboat Drive Units

Since 1978

We manufacture both Airboat Belt and Gear Reduction Drive Units for the Airboat Industry.  

CENTURY DRIVES BELTED UNITS

Century Drive Systems, Inc. is a manufacturer of airboat belted and gear to gear reduction drive units (transmissions) and airboat component parts for the Airboat Industry. We commonly refer to our belted transmissions as a drive units, or airboat drive units. We have several models and ratios to choose from.

The CH-2 airboat drive unit is our 4" wide belt drive system. The CH-3 airboat drive unit is a 5" wide belted reduction unit and our most popular airboat product. The CH-4 airboat drive unit has a 5" wide, 14mm belted drive unit and is available in two higher ratios of reduction.

Our CH-3 Longbelt airboat drive unit lowers your heavy engine and center of gravity by separating the engine crankshaft center and propeller shaft by 41.8 inches. Our CH-3 Counter Rotators can be used with any of the standard CH-3 or the CH-3 Long belt drive units to create an awesome amount of thrust with the same power plant. We are also offering the Counter Rotating unit in the CH-4 with steeper ratios.

The Briggs and Kohler Mini Drive Unit are for the one or two passenger 10' to 15' ft light weight boat systems. This lower cost boat can open a vast market for the general airboaters and small industrial uses.

We offer drive systems for up to 200 HP for the Chevy Echo-Tech 1.4, 1.6, 2.0, 2.4 liter engines. These drives come in a 2:1 ratio. This makes an affordable airboat solution for the general public with a three person boat.

CENTURY DRIVES EXCALIBUR GEAR TO GEAR SYSTEMS

Century Drive Systems offers the Excalibur Gear Drive in five ratios of reduction(2.04, 2.33, 2.50, 2.68, 2.89). This drive is manufactured with 2” wide precision ground gears, our very own customized soft drive, clear chromium conversion finish and a 2 full quart oil capacity.

Our Gear Drives are highly engineered for durability and longevity.  The gears are cut, ground and polished to a very high AGMA standard for a perfect mesh.  With our gear and soft drive design, you will have a smooth quiet drive.  We use the highest quality bearings made with built in oil passages to direct oil where it is needed.  After months of testing, we have chosen Redline Shockproof Gear oil as the best lubricant in our product.

About Us

We are a family owned and operated business with a long-respected history in the Airboating Industry. We have been at the forefront of innovation in new products to enhance thrust and overall performance of your boats.

It all started in 1978 when Robert & Annetta Eakin saw the need to use automotive engines for the airboats as the aircraft engines were getting scarce and expensive. This quickly resulted in the production of what is commonly referred to today as Drive Units or Airboat Transmissions.
