Sierra 18-3454 Water Pump Kit with Housing - Replaces OMC 438592 - Johnson/Evinrude 40/50/60 HP & Jet Outboards

The Sierra 18-3454 Water Pump Kit is a complete cooling system replacement kit for Johnson/Evinrude outboard motors, built to meet or exceed the performance of the original equipment part it replaces. The kit comes with housing included, so you get everything needed to restore proper water circulation to the powerhead without having to source the housing separately. It also includes impeller 18-3104-1, the wear component most responsible for cooling failure over time, so the full water pump assembly can be rebuilt in one job rather than piecemeal.

This kit is designed for Johnson/Evinrude (OMC/BRP) outboards, covering E-Tec 40/50/60 HP All applications as well as 40 HP, 50 HP, 25 Jet, and 30 Jet models from 1995-Up. Sierra engineers this kit for the harsh marine environment, and it is manufactured to the same fit, form, and function as the OEM housing and impeller it replaces, making it a straightforward direct-fit replacement for outboards showing reduced water flow, overheating, or a failed pump indicator.
