Product Number: 18683N
The WAI 18683N is a brand-new 12V permanent-magnet direct-drive (PMDD) starter motor. It is manufactured by Mitsuba and supplied as an OE-quality replacement for Honda original-equipment units. It is cross-referenced directly against Honda part numbers 31200-HN7-003 and 31200HN7003, as well as Remy RS41227 and BMS 31566-C18-36, making it a reliable drop-in alternative sourced from a trusted WAI product line.
The PMDD design eliminates wound-field coils in favour of permanent magnets, which reduces internal friction, lowers current draw on start-up and contributes to a more compact, lightweight unit. Counter-clockwise (CCW) rotation is specified, so confirming your application's rotation requirement before fitting is recommended.
Being brand new — not remanufactured or refurbished — the 18683N arrives ready to fit without the uncertainties that can accompany reconditioned units. The Mitsuba manufacture specification ensures dimensional and electrical compatibility with the original-equipment design it replaces.

A. The WAI 18683N is cross-referenced against Honda 31200-HN7-003 and Honda 31200HN7003. It also replaces Remy RS41227 and BMS 31566-C18-36. These are the OE references published for this part. To confirm the unit suits your specific vehicle or machine, search our cross-referenced catalogue by OEM number or machine model, or ask Simon — every cross-reference shown is backed by our Fit Guarantee.
A. Vehicle application data is not currently published for the WAI 18683N; fit is defined by its OE cross-references — Honda 31200-HN7-003 and 31200HN7003. If one of those numbers matches your machine's original starter, this unit is the correct replacement. You can also search our cross-referenced catalogue by OEM number or ask Simon to confirm suitability for your model.
A. It is brand new — not remanufactured or refurbished. It is manufactured by Mitsuba to OE specification and supplied new in box.
A. The WAI 18683N uses counter-clockwise (CCW) rotation. Confirm your application requires CCW rotation before fitting, as fitting a motor with incorrect rotation direction will prevent the engine from starting.
A. PMDD stands for permanent-magnet direct-drive. Instead of wound-field coils, the motor uses permanent magnets, which reduces internal friction and typically lowers current draw at start-up compared with conventional wound-field designs. The result is a compact, efficient unit that meets the OE specification.
A. Yes — ask Simon, or WhatsApp our team on 07754 288583 with any questions about specifications, suitability, or compatibility.
