Installation Guide

  1. Safety First: Disconnect the engine's battery before starting any work.
  2. Access the Pump: Remove the lower unit (gearcase) from the outboard engine.
  3. Disassemble Housing: Carefully unbolt and remove the water pump housing cover.
  4. Inspect and Remove: Note the rotational direction of the old impeller's vanes before removing it from the driveshaft.
  5. Clean Surfaces: Thoroughly clean the inside of the housing and wear plate, removing any old gasket material or debris.
  6. Install New Impeller: Apply a light coat of marine grease to the housing interior. Insert the new drive key and slide the new impeller onto the shaft, twisting it in the direction of engine rotation to correctly orient the vanes.
  7. Reassemble: Reinstall the water pump housing and tighten the bolts to the torque specified by the manufacturer.
  8. Reinstall Lower Unit: Mount the lower unit back onto the engine.
  9. Test Operation: Reconnect the battery. Using a water supply (flushing muffs), start the engine and verify a steady stream of water is exiting the tell-tale port.

Troubleshooting & FAQ

How do I confirm this fits my engine?

This impeller is designed for Johnson/Evinrude V4/V6 outboards (85-235 HP) from 1973-1978. To ensure a correct fit, please find your specific engine model and year in the "Compatible Engine Models" reference table above. We strongly advise cross-checking the OEM part numbers (0385528, 0389642, 777212) listed in the table with your existing part or service manual.

What are the signs of a failing water pump impeller?

The most common sign of a bad impeller is engine overheating, especially at idle or low speeds. Other indicators include a weak or intermittent water stream from the overboard indicator (tell-tale) and, upon physical inspection, an impeller with cracked, brittle, or permanently bent vanes.

How often should I replace my impeller?

As a crucial part of preventative maintenance, it is recommended to replace the water pump impeller every one to two years or every 100-200 hours of operation. More frequent replacement may be necessary if you operate in saltwater or water with high levels of sand or silt.

Is this a complete water pump rebuild kit?

No, this product listing is for the water pump impeller only. It does not include the water pump housing, wear plate, or gaskets. These components may need to be purchased separately for a complete water pump service.

OEM vs. Aftermarket?

This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.

How fast do you ship and how much does it cost?

We offer fast global shipping—typically 5–15 days worldwide—and standard shipping is free. Expedited options are available at checkout depending on your location.

What is your warranty and return policy?

Returns are accepted within our standard return window (unused & in original condition); please see our policy page or reach out for instructions.
