Yamaha - Water Pump Gasket - Cooling System - 6E0-44315-A0-00

Overview

When you’re servicing a Yamaha water pump, the gasket is one of those parts you never want to reuse. It might look fine at a glance, but once it’s compressed and heat-cycled, it won’t seal the same again. I’ve seen small leaks turn into cooling issues just from skipping this step. Putting in a fresh gasket helps keep everything sealed tight so the pump can do its job without losing pressure.

Key Features

• Reliable Sealing Surface – Creates a tight seal between water pump components to prevent leaks.
• Heat-Resistant Material – Built to handle constant temperature changes inside the lower unit.
• Maintains Cooling Efficiency – Helps preserve proper water pressure and flow through the system.
• Exact Fit Design – Matches original specifications for proper alignment and easy installation.

Engine & Boat Compatibility

Designed for Yamaha 2-stroke outboard engines using standard water pump assemblies. Commonly used on smaller horsepower motors found on skiffs, jon boats, and lightweight fishing setups.

Q: Is sealant needed when installing this gasket?
