Sierra Yamaha Stator for 4 Cylinder Outboard Engines, 18-99260

The Sierra 18-99260 is a replacement stator designed for 4 cylinder Yamaha outboard engines. The stator is a core charging system component that generates AC current as the flywheel rotates past it, supplying power for ignition and battery charging. A worn or failed stator is a common cause of no-spark conditions, weak charging output, or an engine that runs rough or stalls intermittently, and replacing it with a properly sized unit restores reliable charging and ignition performance.

This stator is built for 4 cylinder Yamaha outboard applications and is sold as a direct-fit replacement unit under Sierra part number 18-99260. It ships as a standalone component ready for installation in place of a worn or failed factory stator.

Frequently Asked Questions

What engines does the Sierra 18-99260 stator fit? The 18-99260 is built for 4 cylinder Yamaha outboard engines.

What does a stator do on an outboard engine? A stator generates AC current as the flywheel spins past it, and that current powers the ignition system and charges the battery. The Sierra 18-99260 replaces this component on 4 cylinder Yamaha outboards.

How much does the 18-99260 stator weigh? It weighs 2.3 pounds.

What are the symptoms of a failing stator? A failing stator typically causes weak or no spark, poor battery charging, or an engine that runs rough or stalls, which is why replacing it with a unit like the Sierra 18-99260 can restore normal operation.

Is the 18-99260 a genuine Sierra part? Yes, the 18-99260 is sold under the Sierra brand as part number 18-99260.

Is this stator a direct replacement or does it need modification? The Sierra 18-99260 is designed as a direct replacement stator for 4 cylinder Yamaha outboard engines.

Does the 18-99260 include mounting hardware? The listing covers the stator unit itself, sold under Sierra part number 18-99260.

What is the UPC for the Sierra 18-99260 stator? The UPC is 736983852571.

Can I install the 18-99260 stator myself? The 18-99260 is a standard outboard stator replacement, though installation involves accessing the flywheel area and should be done by someone comfortable with outboard electrical service.

Why choose a Sierra stator over a used or generic part? The Sierra 18-99260 is manufactured to fit 4 cylinder Yamaha outboards specifically, reducing the fitment guesswork that comes with generic or used replacement stators.
