420889726 Armature Stator Coil for Sea-Doo GTI 1503 2015

Stator Coil for Sea-Doo 1503 GTI

This armature/stator coil is a charging and ignition system component that mounts to the engine of the Sea-Doo GTI 1503 and delivers the electrical output needed to keep the battery charged and the ignition firing, with an OEM cross reference of 420889726.

Overview

This stator coil assembly is built for the Sea-Doo GTI 1503, replacing the worn or failed armature that handles charging and ignition on the 1503 engine. The stator coil for Sea-Doo GTI 1503 works by converting engine rotation into electrical current, feeding the battery and ignition circuits so the spark plugs keep firing and the electrical system stays alive during rides. It is the right choice for riders and mechanics repairing a machine that has lost its charging output or is difficult to start.

Built For Performance

• Direct-fit armature and stator coil assembly matched to the 1503 engine's electrical specification
• Wound coil construction intended to produce a stable charging output at the RPM range the 1503 runs
• Cross-referenced to OEM part number 420889726 for straightforward replacement
• Potted and insulated to resist moisture, fuel vapor and vibration in a marine engine bay
• Bolt-on installation that reuses the factory mounting points on the engine case

Fits These Machines

• for Sea-Doo GTI 1503
• for Sea-Doo models equipped with the 1503 four-stroke engine, where the OEM part number matches

On-The-Job Use

• Replacing a failed stator or armature on a personal watercraft that will not charge its battery
• Servicing a hard-starting or no-spark condition traced to the charging and ignition coil
• Refurbishing the electrical system on a Sea-Doo GTI during routine engine work
• Dealer and home-mechanic repairs where an OEM cross-referenced replacement is required

Specs At A Glance

Good To Know

Q: How do I know the stator is the problem? A: If the battery keeps draining while the engine runs, or the machine loses spark as it heats up, the stator coil is a common culprit and should be tested for resistance and output before ordering.

Q: Can I install this myself? A: Yes, it bolts onto the engine case in place of the original armature, though the flywheel cover and related components must be removed first, so basic mechanical tools and a service manual are helpful.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
