Yamaha - Water Inlet Cover - Cooling System Component - 688-45214-02-00

Overview

This is one of those parts that quietly protects your cooling system every time you’re on the water. The water inlet cover helps direct and shield incoming water as it feeds into the lower unit and up through the engine. If it’s damaged or missing, you can end up with restricted flow or debris getting where it shouldn’t. A solid Yamaha replacement keeps your cooling system clean and flowing like it’s supposed to.
