Yamaha - Outer Plate, Cartridge - Cooling System Component - 6P2-44323-00-00

Overview

This is one of those parts you don’t really think about until you’re chasing a cooling issue. I’ve pulled apart plenty of setups where something small like this plate was the reason water flow wasn’t right. When everything’s sealed and sitting correctly, the system runs steady and the motor stays at the right temp. It’s not a flashy component, but it helps keep the whole cooling system doing its job.

Key Features

• Cooling System Seal Support – Helps maintain proper sealing within the cartridge assembly.
• OEM Precision Fit – Built to Yamaha specifications for exact alignment and installation.
• Corrosion-Resistant Build – Designed to handle constant water exposure and marine conditions.
• Maintains Water Flow Integrity – Supports consistent and efficient circulation through the cooling system.

Engine & Boat Compatibility

Designed for Yamaha outboard engines using cartridge-style cooling system components. Commonly used across a range of Yamaha outboards where proper cooling system sealing and flow are critical.
