What can you do with a Rotax 377 that was intended to be used on an ultralight with a belt redrive remote from the engine? The crankshaft has a coupler for an extension shaft. Evidently, the engine was not designed to be fitted with a standard gearbox like most Rotax engines, at least there are no obvious bolt holes, etc., for attachment of a gearbox. Would like to use as a 2 stroke backup for a 1/2 VW which weighs many more pounds with lower HP output.
