GHmarine Water Pump Kit for Johnson Evinrude 75–250 HP – 5001595 OEM-fit impeller rebuild with housing & gaskets

GHmarine 5001595 water pump kit is a complete impeller rebuild set engineered to restore cooling flow on Johnson and Evinrude 75–250 HP outboards.

This kit gathers the housing, neoprene impeller, wear plate, gaskets, seals, coupling tubes and mounting hardware you need to service the water pump on many Johnson, Evinrude and compatible OMC engines. Designed to match OEM fit and function, the parts in this pack replace common part numbers such as 777802, 5551595 and Sierra 18-3315-2 so you can repair a worn pump without buying a full new assembly. Regular inspection and timely impeller replacement keep your engine’s cooling system flowing and help avoid overheating and costly downtime.

Which engines does this GHmarine kit fit?

The 5001595 kit fits a broad range of outboards from mid-range to larger horsepower models. It is intended for Johnson and Evinrude engines from roughly 75 HP up to 250 HP and is compatible where OEM numbers like 777802, 5551595 or Sierra 18-3315-2 are specified.

• Compatible HP range: 75, 80, 90, 100, 105, 115, 120, 125, 130, 140, 150, 175, 185, 200, 225, 250
• Replaces Johnson/Evinrude and OMC part numbers listed above
• Suitable for many late-model V6 and V8 marine outboards within that range

What parts are included and what do they do?

This kit provides every component necessary to rebuild the pump assembly, not just the impeller. That reduces the chance of lost parts during service and ensures sealing and coupling parts are fresh for reliable operation.

• Neoprene impeller — restores water flow through the cooling passages
• Pump housing and wear plate — provide proper clearance and sealing
• Gasket, O-rings, grommets and bolts — replace aged seals and fasteners
• Impeller key and outboard coupling/tubes — ensure correct drive engagement and shaft connection

How do I maintain and install the impeller for best results?

Inspect the impeller every season and plan replacement every two to three seasons or sooner if you notice cracking, missing fins or reduced flow. Follow the engine manufacturer’s service instructions for disassembly, noting shaft alignment and torque specs when reinstalling.

• Check impeller fins for wear or deformation before each season
• Replace seals and gaskets whenever the housing is opened
• Lubricate parts as recommended and torque bolts to spec during assembly

Will this kit match OEM performance and durability?

GHmarine supplies parts engineered to meet marine OEM specifications so the rebuilt pump performs like the original. The neoprene impeller and precision housings are made to tolerate typical saltwater and freshwater conditions when installed and maintained correctly.

• Parts manufactured to OEM dimensions for fit and function
• Neoprene material selected for flexibility and abrasion resistance
• Includes complete hardware set for a full rebuild, reducing future failures

Who this is for: Boaters, marine mechanics and do-it-yourself owners running Johnson, Evinrude or OMC outboards from 75 to 250 HP who want a complete, OEM-compatible repair kit to restore cooling performance. Choose this GHmarine 5001595 kit if you need a full impeller rebuild pack—housing, impeller, seals and coupling hardware—to return your engine’s water pump to reliable service and avoid overheating or damage from a failing impeller.
