Yamaha - Water Pump Housing - Cooling System Component - 6BG-44341-00-00

Overview

When cooling issues show up, the housing is just as important as the impeller itself. This is what holds the pump components in place and directs water through the system properly. If it’s worn or scored inside, you can lose flow even with a brand-new impeller. I’ve seen overheating problems stick around until the housing was replaced.

Key Features

• Controlled Water Flow Path – 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 handle constant water exposure and marine conditions.
