Yamaha - Water Inlet Cover - Cooling System Component - 6J8-45215-00-00

Overview

The water inlet cover is one of those parts that quietly protects your cooling system from problems before they start. If it’s worn, cracked, or not sealing right, you can end up pulling in debris or losing proper water flow. I’ve seen engines run hotter just because this piece wasn’t sitting correctly after a repair. When it’s in good shape, it keeps water moving cleanly into the system and helps everything stay cool under load.

Key Features

• Protects Water Intake – Shields the cooling system from debris entering the lower unit.
• Maintains Proper Flow – Helps ensure steady water intake for consistent engine cooling.
• Durable Construction – Built to handle impact, water exposure, and harsh marine conditions.
• Precision Fit Design – Ensures proper sealing and alignment with Yamaha components.
• Corrosion-Resistant Build – Designed for long-term use in both freshwater and saltwater environments.

Engine & Boat Compatibility

Designed for Yamaha outboard engines with compatible cooling system intake assemblies. Commonly used across small to mid-range outboards on fishing boats, skiffs, and utility vessels. Always confirm part number compatibility before installation.
