Yamaha - Water Pump Housing - Cooling System Component - 6CJ-44341-00-CA

Overview

When you’re working on a Yamaha cooling system, the water pump housing is one of those parts that has to be right or nothing else works like it should. It keeps everything sealed and directs water where it needs to go to keep the motor cool. I’ve seen overheating issues come down to a worn or damaged housing more than once. When it’s in good shape, water flow stays consistent and the engine runs the way it’s supposed to.

Key Features

• Directed Water Flow Design – Channels cooling water efficiently through the pump system.
• Durable Housing Construction – Built to handle constant water movement and internal pressure.
• Precision Fit Structure – Ensures proper sealing and alignment within the water pump assembly.
• Reliable Cooling Support – Helps maintain consistent engine temperature during operation.
• Corrosion-Resistant Material – Designed to withstand harsh freshwater and saltwater conditions.

Engine & Boat Compatibility

Designed for Yamaha outboard engines utilizing a water pump housing within the cooling system. Suitable for a range of mid to high horsepower applications in recreational and working marine environments.
