Yamaha - Cartridge Insert - Water Pump System - 6E0-44322-02-00

Overview

When you’re inside a Yamaha water pump, the cartridge insert is one of those pieces that helps everything stay aligned and working smoothly. It’s not always the first part people think about, but once it wears down, the whole pump can lose efficiency. I’ve seen pumps struggle just because this insert was scored or out of shape. Replacing it during service helps keep water flow strong and consistent.

Key Features

• Internal Pump Alignment – Keeps water pump components properly positioned for smooth operation.
• Wear-Resistant Surface – Built to handle constant contact and movement inside the pump.
• Supports Consistent Water Flow – Helps maintain efficient cooling performance by reducing internal wear.
• OEM Precision Fit – Matches original specifications for proper installation and function.

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 boats.
