Sierra 18-3453 Water Pump Kit with Housing, Replaces OMC 5006511, for Evinrude E-Tec 40/50/60 HP Outboards

The Sierra 18-3453 Water Pump Kit is a complete cooling system replacement kit built for Evinrude E-Tec 40, 50, and 60 HP outboard motors. This kit includes the water pump housing along with the grommet and other components needed to restore proper cooling flow to the powerhead, making it a straightforward way to address a failing or worn factory pump without hunting down individual parts separately. Consistent cooling flow protects the engine block and exhaust housing from overheating, so keeping the water pump in good working order is a routine maintenance item for outboard owners running E-Tec 40/50/60 HP motors.

Because this kit comes with the housing already included, installation follows the pump housing back to the driveshaft area of the lower unit, replacing the original OMC pump assembly in one step. The kit is manufactured to replace OEM part number 5006511, so it installs as a direct equivalent to the original factory pump kit on applicable E-Tec 40/50/60 HP outboards.

Frequently Asked Questions

What is the Sierra 18-3453 water pump kit designed to fit? The Sierra 18-3453 is built for Evinrude E-Tec 40, 50, and 60 HP outboard motors, covering all versions of those horsepower ratings.

Does the 18-3453 kit include the pump housing? Yes, the housing is included with the Sierra 18-3453 kit, so you are not left needing to reuse or source the housing separately.

What OEM part number does the Sierra 18-3453 replace? It replaces OEM number 5006511, so it can be ordered as a direct equivalent for that factory water pump kit on E-Tec 40/50/60 HP outboards.

How much does the 18-3453 water pump kit weigh? The kit weighs 1.06 pounds as shipped.

Is this the same kit as the Sierra 18-3454? No, the 18-3454 is a different Sierra kit made for Johnson/Evinrude 40, 50, 25 Jet, and 30 Jet models from 1995-Up and replaces OEM 438592, while the 18-3453 is specific to E-Tec 40/50/60 HP outboards and replaces OEM 5006511. Ordering the wrong number will get you a kit for the wrong engine.

Will this kit fit a standard (non E-Tec) Evinrude 40 HP motor? The 18-3453 kit is specified for the E-Tec 40/50/60 HP outboard line; fitment for other Evinrude engine families is not covered by this part number.

Is the Sierra 18-3453 a new aftermarket part or a used OEM part? It is a new aftermarket water pump kit manufactured by Sierra as a replacement for OEM number 5006511, not a used or reconditioned OEM part.

What comes in the box with the 18-3453 kit? The kit ships as a single water pump kit that includes the housing and grommet needed for the replacement, packaged as one complete unit under part number 18-3453.

Can I use the 18-3453 water pump kit as routine maintenance, or only for a failure? The Sierra 18-3453 can be used either to replace a failed cooling pump or as part of scheduled maintenance on E-Tec 40/50/60 HP outboards, since it is a full housing-and-pump kit rather than a single wear component.

Does the Sierra 18-3453 include the impeller? The kit is listed as a water pump kit with housing; unlike the related 18-3454 kit, which explicitly lists an included impeller (18-3104-1), no separate impeller part number is called out for the 18-3453.
