Yamaha - Cartridge Insert - Cooling System Component - 6L2-44322-00-00

Overview

When you’re servicing the water pump, it’s easy to focus on the impeller and overlook the surrounding pieces. But if this insert is worn or out of shape, the pump won’t move water the way it should. I’ve seen brand-new impellers underperform just because this part was neglected. Replacing it keeps everything working together so the cooling system stays strong and reliable.

Key Features

• Supports Water Pump Efficiency – Helps guide water flow for consistent cooling performance.
• Precision-Molded Fit – Designed to sit properly within the pump housing for smooth operation.
• Durable Material Construction – Built to withstand constant water exposure and wear.
• Factory-Spec Fitment – Matches Yamaha cooling system components for proper alignment.
• Ideal for Pump Maintenance – Commonly replaced during water pump rebuilds or service.

Engine & Boat Compatibility

Designed for Yamaha outboard engines with compatible water pump systems. Commonly used across small to mid-range outboards on fishing boats, skiffs, and utility vessels. Always confirm part number compatibility before installation.
