Sierra Water Pump Kit for Mercury/Mariner Outboard Motors

The Sierra Water Pump Kit is a replacement outboard water pump repair kit for Mercury and Mariner outboard motors. The water pump (impeller) kit supplies the cooling water flow that keeps your engine at a safe operating temperature. Replacing worn parts on schedule helps prevent overheating and engine damage.

Key Features:

• Aftermarket replacement designed to match the form, fit and function of OEM Mercury/Mariner water pump service parts
• Includes a replacement impeller as the core wear item of the cooling system
• Built to circulate cooling water through the powerhead and lower unit
• Backed by Sierra, a long-established marine engine parts brand known for quality aftermarket components
• Suited to routine maintenance, seasonal service and overheating repairs

Kit contents and specifications vary by application, so check the individual item listing for the exact part number. Regular water pump service is one of the most cost-effective ways to protect your outboard and keep it running reliably on the water.
