Yamaha Water Pump Housing - Cooling System Component - 67C-44311-10-00

Overview

On these smaller jet drive setups, the water pump housing is one of the main pieces keeping the engine cool under load. It holds everything in place around the impeller and keeps water moving the way it should. I’ve seen worn housings cause weak flow even after replacing the impeller, which throws people off. When this part is solid, the cooling system stays consistent and the engine runs without overheating.

Key Features

• Genuine Yamaha Fitment – Designed to match factory pump components and mounting points.
• Consistent Cooling Flow – Helps maintain steady water pressure through the system.
• Sealing Surface Stability – Provides proper sealing to prevent leaks and efficiency loss.
• Durable Marine Construction – Built to handle water exposure, heat, and vibration.
