Troubleshooting & FAQ

How do I know if this kit fits my specific engine model?

This kit is designed for Johnson/Evinrude 14HP (1988–1989), 25HP (1979–1997), and 28HP (1986–1998) 2-stroke outboards with split case lower units. Please check the "Engine & Model Compatibility" table and verify your OEM part number against the "Part Number Matrix" to ensure an exact match.

What are the signs of a failing water pump impeller?

Common signs include an engine overheating alarm, a weak or non-existent stream of water from the tell-tale outlet, or visible cracks, brittleness, and damage on the old impeller's rubber vanes upon inspection.

How often should the water pump impeller be replaced?

For preventative maintenance, it is recommended to inspect and/or replace the impeller every 1–2 years or every 100–200 hours of operation. Service intervals should be shorter in saltwater or silty/sandy conditions.

Is this for a split case or one-piece gearcase?

This kit is specifically for outboards with a split case lower unit design and thru-prop exhaust. It will not fit one-piece gearcases.
