Product Overview
Replace a weak, burned, or failed stator with this 18-coil 3-wire magneto stator, designed for select Sea-Doo personal watercraft models using OEM reference number 420889728.
The stator is an important part of the Sea-Doo charging system. It helps generate electrical power while the engine is running, supporting the battery, ignition system, sensors, and other electrical components. If your Sea-Doo GTI, GTX, GTR, RXP, RXT, WAKE, WAKE PRO, or FISH PRO has weak charging, low battery voltage, unstable electrical output, or stator-related failure, replacing the stator may help restore normal charging performance.
Built with a metal lamination core and copper windings, this replacement stator is designed for stable conductivity, heat resistance, and reliable marine use. Please compare your original stator’s OEM number, wire count, plug layout, mounting hole distance, and dimensions before ordering.

Fitment FAQ
Will this part fit my specific model and year?
This stator is designed for select Sea-Doo personal watercraft models using OEM reference number 420889728, including GTI, GTI SE, GTX, GTR, RXP, RXP-X, RXT, WAKE, WAKE PRO, and FISH PRO models from 2018–2021 depending on the exact submodel. Please compare your original stator’s OEM number, wire count, connector layout, inner diameter, outer diameter, mounting hole distance, and thickness before ordering.
Do I need to match the OEM part number?
Yes, matching the OEM part number is strongly recommended. This stator replaces OEM 420889728. However, OEM number alone is not enough. Please also confirm that your original stator uses the same 18-coil 3-wire design, connector style, mounting hole spacing, inner diameter, outer diameter, and overall thickness.
What models or situations does this part not fit?
This part does not fit Sea-Doo models that use a different stator diameter, different wire count, different connector layout, different mounting hole spacing, or a different OEM stator design. It is also not suitable if your issue is caused only by a weak battery, faulty regulator rectifier, damaged wiring, burned connector, poor ground connection, or another charging system component.
What should I check before ordering?
Before ordering, please check your Sea-Doo’s make, model, year, engine version, OEM part number, original stator coil count, wire count, connector shape, inner diameter, outer diameter, mounting hole distance, stator thickness, and overall shape. For best fitment, compare the product photos and specifications with your original stator before purchase.
