UANOFCN Outboard Water Pump Kit for 75-250 HP Johnson Evinrude, Complete Rebuild with Neoprene Impeller and Housing

The UANOFCN 5001595 outboard water pump kit is a complete replacement set designed to restore cooling circulation for Johnson and Evinrude 75–250 HP outboard engines.

This kit brings together the parts most commonly replaced when an outboard lower unit is overheating or losing coolant flow: housing and cup, neoprene impeller, gasket and wear plate, coupling assemblies, O-rings, grommets and bolts. It’s engineered as a repair alternative to OEM assemblies and lists cross-reference numbers so you can verify fit for your specific horsepower and model year before you buy.

How do I know this kit fits my Johnson or Evinrude engine?

Compatibility depends on horsepower range and the year-specific pump design. The UANOFCN 5001595 is intended for a wide range of Johnson/Evinrude/OMC outboards from 75 HP up to 250 HP; always compare cross-reference numbers and visual pump layout with your existing parts.

• Fits many 75–250 HP Johnson/Evinrude OMC outboards
• Replaces BRP 777802, 5551595, 435929, Sierra 18-3315-2, GLM 12000
• Confirm fit by matching part numbers and pump housing shape
• Check model year and lower-unit configuration before installation

What components are included and why they matter?

The kit arrives as a full service package so you won’t need to source small fasteners or seals separately. The included parts let you address the typical failure points in an outboard cooling circuit: impeller wear, damaged housing, and deteriorated gaskets or O-rings.

• Neoprene impeller plus impeller key for water circulation
• Housing and cup with gasket and wear plate to reseal the pump
• O-rings, grommets and bolts for a complete rebuild
• Coupling assembly/tube pieces to connect to lower-unit drive

How difficult is installation and what tools do I need?

Installation is straightforward for anyone comfortable with basic outboard maintenance and lower-unit removal. The kit includes all small hardware so you mainly need common hand tools, torque specs, and attention to alignment to avoid leaks or premature wear.

• Requires removal of lower unit and access to pump housing
• Typical tools: socket set, torque wrench, screwdrivers, sealant as needed
• Follow engine service manual torque values and alignment notes
• Replace gaskets and grommets and inspect coupling for looseness

Will using this kit change performance or longevity?

Replacing worn pump elements restores designed coolant flow, which helps the engine run within normal temperature ranges when installed correctly. Longevity depends on correct installation, regular inspection, and avoiding debris ingestion in shallow or weedy water.

• New impeller restores water flow and pressure characteristics
• Fresh seals reduce risk of external leaks and cavitation
• Inspect for debris and replace if blade edges are damaged
• Periodic checks prolong pump life and engine cooling reliability

Who is this for: The UANOFCN 5001595 kit is aimed at boat owners, DIY mechanics and marina technicians who need a comprehensive water pump repair set for Johnson/Evinrude outboards in the 75–250 HP range. If you maintain your own engine and want a complete package of parts and fasteners to rebuild the lower-unit pump without sourcing multiple small components, this kit provides the components commonly required for a full pump refresh. Always verify compatibility with your engine’s part number and service manual before ordering or starting work.
