Parts Player Kawasaki starter for JS440 & JS550 (1976–1995) — 12V CCW, 9-tooth, 224mm direct-fit replacement

Parts Player starter is a 12V, high-torque replacement starter engineered to fit Kawasaki JS440 and JS550 jet skis from the late 1970s through the mid-1990s.

Built for compatibility across multiple model years and a long list of OEM references, it delivers CCW rotation, 9 teeth, and a compact 224mm overall length.

How does this unit compare to OEM and other aftermarket starters?

The Parts Player starter is positioned as an OEG-style replacement that matches many OEM part numbers, making it a direct swap in most applications. While manufactured abroad, it is built to align with original dimensions and engagement specs so it fits the same mounting points and electrical connections as the factory unit.

• Listed as new condition and cross-referenced to numerous OEM codes for easy verification.
• Designed to replace high-torque factory starters used on older Kawasaki jet skis.
• Check polarity and terminal types to ensure electrical compatibility during installation.

What should I prepare for installation and service life expectations?

Installation requires standard hand tools and attention to cable routing and bolt torque to avoid damage. Because the part ships without mounting bolts, have the correct fasteners on hand or reuse OEM hardware when undamaged.

• Bring appropriate bolts or verify existing mounting hardware condition prior to fitment.
• Inspect wiring, switches, and battery condition; weak batteries can mimic starter failure.
• Follow torque specs from Kawasaki service manuals; test engagement and free spin after fitment.

Who is this for: This starter is aimed at owners, mechanics and restoration specialists working on classic Kawasaki jet skis—particularly JS400, JS440 and JS550 models—who need a reliable, cross-referenced replacement that matches OEM dimensions and starts the engine with high torque. Ideal for people restoring older personal watercraft, replacing a failed OEM starter, or maintaining a fleet of vintage jet skis who require clear part number compatibility and straightforward installation.
