Yamaha - Cartridge Insert - Water Pump Component - 6BX-44322-00-00

Overview

When you’re servicing a water pump, this is one of those parts that makes a bigger difference than it looks. The cartridge insert works with the impeller and housing to keep water moving efficiently through the system. If it’s worn or scored, you’ll lose flow even if everything else is new. I’ve seen cooling issues cleared up just by replacing this during a routine pump service.

Key Features

• Supports Impeller Operation – Provides proper surface and structure for efficient water movement.

• Maintains Cooling Efficiency – Helps ensure steady water flow through the system.

• OEM Fit Accuracy – Matches Yamaha factory specs for correct alignment and installation.

• Wear Resistant Construction – Built to handle constant contact and water exposure.
