Yamaha - Water Tube Assembly - Cooling System Water Transfer - 6EE-G4360-10-00

Overview

Water tubes are one of those parts you don’t think about until cooling issues start creeping in. I’ve seen engines run hot just because this tube was bent, clogged, or not sealing right after a lower unit install. It’s what carries water up from the pump to the powerhead, so it has to be straight and sealed every time. When it’s right, the cooling system just does its job and you don’t have to worry about it.

Key Features

• Direct Water Flow Routing – Transfers cooling water efficiently from the lower unit to the engine.
• Consistent Cooling Support – Helps maintain proper engine temperature under load.
• Durable Tube Construction – Built to handle constant water flow, heat, and vibration.
• Proper Alignment Fit – Designed to seat correctly between water pump and powerhead connections.
• Exact Yamaha Replacement – Matches factory specifications for reliable installation and performance.

Engine & Boat Compatibility

Designed for Yamaha outboard engines utilizing an internal water tube for cooling system flow. Commonly used across a range of Yamaha outboards in recreational and commercial marine applications. Suitable for freshwater and saltwater environments where dependable cooling performance is critical.
