Sierra Water Pump Impeller Repair Kit for Mercury/Mariner Outboard

The Sierra Water Pump Impeller Repair Kit for Mercury and Mariner outboard motors restores cooling system performance. It is also known as a water pump rebuild kit or impeller service kit. The water pump pushes water through the engine's cooling passages. A worn impeller can lead to overheating and costly engine damage.

Key Features:

• Aftermarket replacement engineered to replace the original water pump service components on Mercury and Mariner outboards
• Flexible impeller designed to build consistent water flow and pressure for engine cooling
• Kits are built for marine use, including saltwater
• Designed to bring the pump back to proper operating condition during routine maintenance or an overheating repair
• Backed by Sierra International, a long-established supplier of marine engine parts

Replacing the impeller as part of regular outboard maintenance helps protect the powerhead and keeps the engine running at the right temperature. Select the child item that matches your engine for the exact kit configuration.
