Yamaha - Cartridge Insert - Cooling System Component - 6AW-44322-00-00

Overview

This is one of those small internal pieces that keeps the cooling system doing its job without any drama. When everything’s working right, water moves clean through the system and the engine stays right where it should temperature-wise. But if this insert gets worn or out of place, you can end up chasing cooling issues that don’t make much sense at first. It’s a simple part, but it plays a big role in keeping water flow controlled and consistent.

Key Features

• Controlled Water Flow Support – Helps regulate how water moves through the cooling system.
• Precision Internal Fit – Designed to sit correctly within the cartridge assembly for proper function.
• Durable Marine Material – Built to handle continuous water exposure and heat cycles.
• Cooling System Stability – Supports consistent engine temperature by maintaining proper flow paths.

Engine & Boat Compatibility

Designed for Yamaha outboard engines using this style of cooling system cartridge insert. Commonly found in modern Yamaha applications where proper water flow control is essential for engine protection.
