Engineered Marine Products Water Pump Kit with Housing 46-13159 - Replaces 18-3150 - Mercruiser Bravo/Inboard

The Engineered Marine Products 46-13159 is a complete water pump kit with housing for Mercruiser Bravo drives and inboard engines equipped with a plastic pump body, serial number 3040411 and above. The kit is built as a direct replacement for the Mercury/Quicksilver 18-3150 water pump kit, so it installs in place of the original assembly without modification.

Each kit includes a complete stainless steel pump with pulley along with the pump housing, giving you the core cooling-system components in a single package rather than sourcing the pump, pulley, and housing separately. The stainless steel construction is intended to hold up to continuous exposure to raw water and the corrosive marine environment better than lower-grade materials, supporting reliable coolant circulation through the engine's raw water cooling system.

This kit is intended for Mercruiser Bravo and inboard applications specifically using the plastic pump body design, starting at serial number 3040411. It is backed by a 1 year manufacturer warranty and ships as a single-item kit ready to install.
