Complete Your Purchase
Restore optimum performance to your MerCruiser cooling system and make the most of the season
Marine engines rely on the water pump to maintain optimum operating temperatures. Any restriction to the water flow can rob the engine of performance and efficiency and possibly result in overheating the engine. Sierra makes sourcing parts to service MerCruiser or Mercury water pumps easy by packaging all the necessary parts in a single kit and eliminating the extra time to search and source individual parts. Each component in the kit is engineered to meet or exceed manufacturer specifications. Sierra water pump kits let you focus on restoring the water pump and not on sourcing parts, so that you can get back on the water sooner.
Key Features
- Kit components are engineered to meet or exceed OEM specifications
- Pre-packaged kit eliminates time searching and sourcing individual parts
- Kit includes: pump housing and base, impeller, water tube guide, impeller plate, O-rings, and gaskets.
