Yamaha Lower Drain Screw Seal

Yamaha Lower Drain Screw Seal – Stop Leaks Before They Start

This small but mighty Yamaha Lower Drain Screw Seal is an essential gasket that ensures a watertight seal around your outboard's lower unit drain screw. Replacing this seal during every gear oil change is the simplest way to prevent oil leaks and protect your gearbox from costly water intrusion.

Key Features

• OEM Quality: Manufactured to Yamaha's exact specifications for a perfect, reliable fit.
• Leak Prevention: Creates a secure, drip-free seal between the drain screw and lower unit housing.
• Marine-Grade Material: Resistant to gear oil, saltwater, and temperature extremes for long-lasting performance.
• Routine Maintenance Essential: Should be replaced with every gear oil service to maintain seal integrity.
• Affordable Insurance: A low-cost part that prevents expensive lower unit damage.

Never reuse an old drain screw seal — once compressed, it loses its sealing ability. Keep a few on hand so you're always ready for your next service.

Please verify compatibility with your specific Yamaha outboard model before ordering.
