Product Number: 18912N
The WAI 18912N is a brand-new 12V Mitsuba PMDD starter motor designed to replace original Polaris equipment. It carries OE cross-references Polaris 3089879 and Polaris 3090192, making it a direct like-for-like replacement for those original Polaris starter motors.
Built to the Mitsuba PMDD design, this starter motor runs on a 12V supply with clockwise rotation and a 10-tooth pinion, matching the engagement and output characteristics of the original equipment it replaces. The PMDD (Permanent Magnet Direct Drive) construction delivers reliable cranking without the added complexity of a gear-reduction stage.
As a brand-new unit rather than a remanufactured or reconditioned part, the 18912N requires no core exchange and arrives ready to fit straight away. Use the OE references below or search our cross-referenced catalogue by Polaris part number to confirm suitability for your machine before ordering.
