Which engines and Sea‑Doo models will this starter work with?

This starter is intended for Rotax 782cc, 2‑stroke engines and many Sea‑Doo PWC and sportboat models from the mid‑1990s to 1999. Verify fit by matching engine model and year before ordering to ensure compatibility.

• Rotax engines: 787 RFI (1998) and 787 (1995–1999) 782cc 2‑stroke
• Sea‑Doo PWC: GSX, GTX, GTX RFI, SPX, XP models covering 1995–1999

How is this starter constructed and why does that matter?

The starter uses premium materials and precision machining to replicate OEM form and function, ensuring durability in corrosive marine environments. Its PMDD design delivers reliable cranking while remaining compact for tight engine bays.

• Materials: copper, steel, aluminum components for strength and conductivity
• Design: PMDD (Permanent Magnet Direct Drive) for efficient torque delivery
• Finish: machined pinion and housing to reduce wear and maintain alignment
• Weight and size: about 5.22 lbs for easy handling during installation

What are the technical specifications I should check before buying?

Confirm key measurements and characteristics to avoid fitment issues: voltage, rotation, teeth count, pinion outer diameter, and mounting thread size. These details match common OEM requirements for the listed Rotax/Sea‑Doo engines.

• Voltage: 12 volts — industry standard for these PWCs and sportboats
• Rotation: counterclockwise (CCW) — matches original starters for these engines
• Teeth/Splines: 9 teeth/splines; pinion OD 29.1 mm (1.146 in)
