Yamaha Tube, Water - Cooling System Component - 67F-44361-30-00

Overview

The water tube is one of those parts you don’t think about until cooling problems show up. It’s responsible for carrying water from the lower unit up into the engine, and if it’s off, the whole system suffers. I’ve seen engines run hot just from a tube being slightly bent or not sealing right. When it’s lined up properly, water flow stays consistent and everything runs the way it should.

Key Features

• Efficient Water Transfer – Moves cooling water from the lower unit to the engine for proper circulation.
• Genuine Yamaha Fitment – Designed to match factory routing and connection points precisely.
• Supports Engine Cooling – Helps maintain steady water flow for consistent temperature control.
• Alignment Stability – Ensures proper positioning within the cooling system during operation.
• Durable Marine Construction – Built to handle water exposure, heat cycles, and vibration.

Engine & Boat Compatibility

Compatible with select Yamaha outboards using this water tube. Verify fitment based on your specific engine model.
