Yamaha - Water Tube - Cooling System Component - 6GH-44361-00-00

Overview

When you’re working on Yamaha cooling systems, the water tube is one of those parts you don’t think about until something goes wrong. I’ve seen engines overheat just because of a damaged or misaligned tube during a lower unit install. The Yamaha Water Tube 6GH-44361-00-00 is what carries water from the pump up into the powerhead, so it has to be right. If it’s sealed and aligned properly, the whole cooling system does its job without a second thought.

Key Features

• Direct Cooling Water Transfer – Routes water from the lower unit pump to the engine for proper cooling.

• Yamaha Engineered Fit – Designed to align correctly with factory cooling system components.

• Durable Tube Construction – Built to handle constant water flow, pressure, and engine vibration.

• Supports Consistent Cooling Performance – Helps maintain steady water supply to prevent overheating.

• Service-Ready Replacement – Ideal for use during lower unit service or cooling system repairs.

Engine & Boat Compatibility

The Yamaha Water Tube 6GH-44361-00-00 is designed for Yamaha outboard engines equipped with a lower unit water pump cooling system.

It is commonly used during lower unit installation or cooling system service where proper water transfer from the pump to the engine is critical. Always confirm compatibility using your engine model and parts diagram before installation.
