Yamaha - Cartridge Insert - Cooling System Component - F2.5 - 6L5-44322-00-00

Overview

On smaller outboards like the F2.5, the cooling system is simple but it still needs to be right. When parts inside the pump housing start to wear, you’ll notice weaker water flow or inconsistent cooling. This cartridge insert is one of those internal pieces that helps keep everything moving the way it should. It’s a small part, but replacing it during a service can make a big difference in how reliably the motor runs.

Key Features

• Supports Water Pump Function – Helps guide water flow efficiently through the cooling system.
• Precision-Molded Design – Built to fit properly within the pump housing for consistent operation.
• Durable Material Construction – Handles constant water exposure without breaking down quickly.
• Factory-Spec Fitment – Designed to match Yamaha components for proper installation.
• Ideal for Pump Service – Commonly replaced during water pump maintenance or rebuilds.
