Glasair III

FWF for Glasair III

The first firewall forward engine package for Glasair III belongs to a legacy customer of Geared Drives who actively participated in his installation. Though it is a bit busier under the cowl than preferred, the anticipated great performance from this airframe with this engine was met.


All aluminum water cooled Chevrolet LS3 engine with altitude compensating electronic fuel injection. Spur gear propeller speed reduction unit with fully automatic centrifugal clutch and flywheel assembly. Ships already assembled and test run for bolt on application to Glasair III firewall. Custom programmed ECM and wiring harness. You add your own propeller governor, propeller, fuel pumps, and fuel regulator/filter.
