Yamaha - Water Inlet Cover - Cooling System Component - 6L2-45215-00-00

Overview

The water inlet area takes constant abuse—sand, debris, and whatever else gets pulled in while you’re running. When the cover starts wearing down or gets damaged, it can affect how water feeds into the cooling system. I’ve seen engines run hotter than they should just because this piece wasn’t sealing right. It’s a simple part, but it plays a big role in keeping your motor running cool and steady.

Key Features

• Maintains Water Flow Path – Helps direct water properly into the cooling system.
• Protective Inlet Coverage – Shields internal components from debris and external damage.
• Corrosion-Resistant Build – Designed to withstand constant exposure to marine environments.
• Factory-Spec Fitment – Matches Yamaha lower unit design for proper alignment and sealing.
• Durable Construction – Built to handle wear from regular use and water impact.

Engine & Boat Compatibility

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