Yamaha – Water Tube - Cooling System Component - 62Y-44361-00-00

Overview

Water flow is everything on an outboard, and this tube is what carries it where it needs to go. When one of these gets bent, clogged, or corroded, you’ll start seeing overheating issues fast. I’ve pulled plenty of lower units where a worn water tube was the hidden problem behind poor cooling. Keeping this piece in good shape makes sure your motor stays properly cooled, especially under load.

Key Features

• Direct Cooling Water Transfer – Routes water efficiently from the lower unit to the powerhead.
• Genuine Yamaha Fitment – Built to precise factory dimensions for proper alignment and flow.
• Corrosion-Resistant Construction – Designed to handle constant water exposure in marine environments.
• Maintains Cooling Efficiency – Helps prevent overheating by ensuring steady water circulation.
• Straightforward Replacement – Fits cleanly into the cooling system during lower unit service.

Engine & Boat Compatibility

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