Is this a genuine original part?

This is a premium quality aftermarket replacement part from 4Drive, manufactured to meet or exceed original equipment (OE) standards for fitment and cold-start performance.

How do I know if it is compatible?

We recommend checking the SKU/MPN and Cross Reference list provided above. If your original starter motor is a Denso unit for a 500-800cc Rotax engine from the listed years, this is the correct drive.

Will this fit the newer E-TEC engines?

This specific 9-tooth drive is designed for the standard Denso/Bombardier starter systems found on carb and SDI models. Please verify your tooth count and OEM number if fitting to a late-model E-TEC engine.
