Installation Notes

Disconnect the battery and shift the outboard into the neutral position.
Remove the lower unit (gearcase) by unbolting it from the engine's midsection. Be prepared for it to be heavy.
Locate and unbolt the water pump housing to expose the old impeller and wear plate.
Carefully note the rotational direction of the old impeller fins as you remove it.
Clean all surfaces of debris and corrosion. Replace the wear plate, gasket, key, and impeller.
Lubricate the new impeller and inside of the housing with a marine-safe lubricant.
Install the new impeller, ensuring the fins are oriented correctly (typically by turning the driveshaft clockwise while pushing the housing down).
Reinstall the housing and torque the bolts to the manufacturer's specification.
Re-attach the lower unit, ensuring all connections (shift linkage, drive shaft) are properly aligned.
Once assembled, start the engine in water and verify a steady stream of water from the tell-tale outlet.

Troubleshooting & FAQ

How do I know if my water pump is failing?

Common signs include a weak or non-existent water stream from the "tell-tale" outlet, engine overheating alerts, or a melted/distorted impeller discovered during inspection. Reduced cooling performance can cause severe engine damage.

What is the recommended replacement interval for an impeller?

For optimal reliability, most marine mechanics recommend replacing the water pump impeller every 1–2 years or every 100–200 hours of operation, whichever comes first. This interval can be shorter if you frequently operate in sandy, silty, or saltwater conditions.

How does this aftermarket kit compare to the OEM version?

This kit is engineered to meet or exceed OEM specifications for fit, form, and function. It uses comparable materials, such as a durable neoprene-compound impeller and corrosion-resistant alloys, to ensure reliable performance and service life.

Why does the kit include multiple part numbers for some components?

Over the long production run of these engines, manufacturers often update or supersede part numbers. The multiple numbers listed (e.g., for the gasket) indicate that our single component replaces several different OEM versions, ensuring broad compatibility.

What are the most critical steps during installation?

Ensuring the impeller fins are facing the correct rotational direction and adequately lubricating the impeller and housing interior are crucial. Rushing these steps can cause premature failure. Also, confirm the woodruff key is properly seated on the driveshaft.

OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
