Starter Motor Sea-Doo 800 8-Tooth Bendix

High-Torque Replacement for Rotax 787/800 Engines

This premium 12-volt starter motor is engineered specifically for Sea-Doo personal watercraft equipped with the 800 Series (787cc) Rotax engine. Unlike standard 9-tooth versions, this unit features an 8-tooth Bendix gear. This design modification provides a mechanical advantage, offering higher cranking torque to overcome the high compression of the 787cc engine, ensuring faster and more reliable starts even with a standard battery.

RELIABILITY: Manufactured with high-quality copper and silver contacts and sealed bearings to resist the harsh marine environment.

Key Features

  • 8-Tooth Bendix: Increased torque for easier starting
  • Direct Fit: No modifications required for 800 models

Questions & Answers

Is this a genuine original part?

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

How do I know if it is compatible?

We recommend checking the SKU/MPN and Cross Reference list provided above. If your original part number matches any of these, it is a guaranteed fit for the 787cc/800 engine.

Will this 8-tooth gear work if my original was 9-tooth?

Yes. Sea-Doo originally used 9-tooth starters but later switched to the 8-tooth design for many 800 series models to provide better starting torque. It is a direct "High Torque" upgrade for 9-tooth original applications.
