Yamaha - Cartridge Insert - Water Pump Housing Component - 69D-44322-00-00

Overview

This is one of those parts you usually only deal with when you’re deep into a water pump service. The cartridge insert helps guide and support water flow through the pump housing, and if it’s worn or damaged, you can lose efficiency without realizing it right away. I’ve seen pumps struggle just because this piece wasn’t sealing or aligning correctly. When everything’s tight and in place, the cooling system does its job without any drama.

Key Features

• Water Flow Channel Support – Helps direct and stabilize water movement inside the pump housing.
• Precision Yamaha Fitment – Built to match factory tolerances for proper alignment and sealing.
• Durable Marine Construction – Designed to handle constant water exposure and internal pump friction.
• Supports Pump Efficiency – Helps maintain strong and consistent cooling system performance.

Engine & Boat Compatibility

Compatible with Yamaha outboard engines using cartridge-style water pump systems. Commonly found across a variety of Yamaha motors on recreational, inshore, and offshore boats.
