Yamaha - Water Pump Housing - Cooling System Component - 6BL-44311-00-00

Overview

When you’re dealing with cooling issues, the housing is just as important as the impeller itself. This is the structure that holds everything in place and directs water through the pump the way it should. If it’s worn, warped, or scored inside, you’ll lose efficiency even with new parts installed. I’ve seen cooling problems stick around until the housing was replaced.

Key Features

• Structured Water Flow Channel – Directs water efficiently through the pump system.

• Supports Pump Components – Houses the impeller and internal parts for proper operation.

• OEM Fit Accuracy – Matches Yamaha factory specs for correct alignment and sealing.

• Corrosion Resistant Construction – Built to withstand constant water exposure and harsh marine use.
