Yamaha Outer Plate, Cartridge - Cooling System Component - 67F-44323-00-00

Overview

This is one of those parts in the water pump system that doesn’t look like much but plays a big role in how well your engine cools. The outer plate helps guide water through the cartridge and keeps everything aligned so flow stays consistent. I’ve seen worn plates cause weak pressure even with a new impeller installed. When it’s in good shape, the cooling system runs steady and does exactly what it’s supposed to.
