Troubleshooting & FAQ
Q: How do I confirm this kit fits my engine?
A: This kit is designed for most Johnson/Evinrude 85-300 HP V4, V6, and V8 outboards manufactured between 1979 and 2006. To ensure a correct fit, please carefully review the "Compatible Engine Models" table above and cross-reference your OEM part number (5001594). Note: This kit is not compatible with SL models.
Q: What are the signs my water pump is failing and needs replacement?
A: Common signs of a failing water pump include the engine overheating, a weak or inconsistent stream of water from the "tell-tale" outlet, or finding cracked/missing vanes on the old impeller during a physical inspection.
Q: How often should I replace my water pump impeller?
A: For optimal engine protection, we recommend inspecting the water pump and impeller annually and planning a full replacement every 1-2 years. If you operate primarily in saltwater or areas with high levels of sand or silt, more frequent replacement may be necessary.
