Engineered Marine Products Complete Water Pump and Seal Kit 26-01800-B for Mercury Outboard Cooling Systems

The Engineered Marine Products Complete Water Pump and Seal Kit, part number 26-01800-B, is a cooling system rebuild kit designed for Mercury outboard engines. It provides the components needed to restore proper raw-water circulation through the engine's cooling system, which is essential for preventing overheating and protecting the powerhead. The kit is built to OEM standards, giving installers a direct, reliable replacement solution rather than a partial or mismatched assortment of parts.

Engineered Marine Products has supplied both OEM and aftermarket marine channels for over 40 years, engineering and sourcing components that meet original equipment quality expectations at a competitive price point. This water pump and seal kit carries a machined exterior finish and ships as a compact, complete package measuring 4 x 4 x 4 inches and weighing 1.112 pounds, making it easy to store and handle during a routine cooling system service.

This kit is intended for technicians and boat owners performing a water pump rebuild or seasonal cooling system maintenance on compatible Mercury outboard applications. Installing a complete kit at one time, rather than replacing individual worn components separately, helps ensure all wear parts are renewed together and reduces the chance of a follow-up failure from an overlooked seal or gasket.
