Troubleshooting & FAQ

How do I confirm this fits my specific Yamaha outboard?

The surest method is to check your engine’s official parts diagram or service manual. If it lists 90201-43M00 as the required part, this washer will fit.

What are signs of a worn steering washer?

Symptoms often include excessive play or "slop" in the steering, unusual noises (clicking or grinding) when turning, or increased stiffness. A visual inspection may also reveal a cracked, deformed, or heavily corroded washer.

When should this washer be replaced?

Replace it during any major service of the steering system, if you notice signs of wear, or if the component is removed for any other repair. It's a low-cost part that is critical for safe steering.

Can I install this part myself?

While installation is possible for those with mechanical experience, it involves the critical steering system. For safety and correct function, we strongly recommend professional installation by a qualified marine technician who has the proper tools and service manuals.

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
