Geo Metro®/Suzuki® Auto Engine Conversions

Now in its 15th year of selling products related to the Suzuki® line of auto engines, Raven Redrives Inc. is pleased to present its line of reduction drive kits for use in airboats and light aircraft. Power plants are available for aircraft needing 58 to 115+ horsepower in a lightweight, reliable, fuel efficient, and powerful package designed around the readily available 1.0 liter and 1.3 liter Geo® Metro/ Suzuki® auto engines.

Our goal from the beginning has been to provide a cost-effective alternative to the popular Rotax® line of small aircraft engines. We have been working hard to offer a reliable drive system and complete engine packages that will be a cost competitive alternative to the Rotax® 503, 582, 912, 912S and even 914 power-plants.

We now offer a number of versions of reduction drives that have been designed from the ground up for reliability, as well as adaptability to a broad range of aircraft kits.
