Yamaha Tube, Water - Cooling System Component - 67C-44361-00-00

Overview

The water tube is one of those parts that quietly keeps your engine from getting into trouble. It carries cooling water from the lower unit up into the powerhead, and if it’s not lined up right, you’ll feel it in rising temps pretty quickly. I’ve seen engines overheat just from a tube being slightly off during reassembly. When it’s seated properly and in good shape, water flow stays steady and the engine runs exactly how it should.

Key Features

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

Engine & Boat Compatibility

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