Yamaha - Gasket, Water Pump - Cooling System Component - 682-44315-A0-00

Overview

This is one of those small parts I never reuse when working on a Yamaha water pump. The gasket is what keeps everything sealed between the housing surfaces, and if it’s compromised, you’ll lose pressure and cooling efficiency. I’ve seen engines run hotter than they should just because of a worn gasket. Putting in a fresh one helps the whole system stay tight and do its job properly.

Key Features

• Sealing Surface Integrity – Creates a tight seal between water pump components to prevent leaks.
• Genuine Yamaha Fitment – Designed to match factory housing surfaces for proper alignment.
• Supports Cooling Efficiency – Helps maintain consistent water pressure and flow.
• Heat and Pressure Resistant – Built to hold up under engine temperature and operating conditions.
• Direct Replacement Design – Installs easily during water pump service or rebuild.

Engine & Boat Compatibility

Compatible with select Yamaha outboards using this water pump gasket. Verify fitment based on your specific engine model.

Q: Can I reuse an old gasket if it looks fine?
A: It’s not recommended, as even small imperfections can cause leaks.

Q: Is installation difficult?
A: No, it’s a simple step during water pump service, just make sure surfaces are clean.
