Product Number: 18645N
The WAI 18645N is a brand-new 12V Mitsuba PMDD starter motor. It is replacing Remy RS41196 and Polaris original-equipment references 3084981 and 3090188. It is a direct OE-replacement unit engineered to Mitsuba's Permanent Magnet Direct Drive (PMDD) design specification, delivering the cranking performance expected of a genuine-quality starter at aftermarket value.
PMDD architecture eliminates the reduction-gear stage found in conventional starters, keeping the unit compact and lightweight while maintaining strong torque transfer directly to the ring gear. Clockwise rotation (viewed from the pinion end) matches the OE engagement direction, ensuring correct mesh with the flywheel without modification.
All 18645N units are supplied brand new — not remanufactured — and are built to meet or exceed original-equipment standards for electrical and mechanical performance.
