Troubleshooting & FAQ
How do I know if my water pump impeller is failing?
Common signs of a worn or failed impeller include a weak or inconsistent water stream from the engine's tell-tale outlet, an engine overheating alarm, or an abnormally high temperature reading on your gauge.
What is the recommended replacement interval for this impeller?
For optimal reliability and to prevent engine damage, boat mechanics recommend replacing the impeller every 100-200 operating hours or at least once per boating season, whichever comes first.
How can I confirm this kit will fit my engine?
This kit fits specific Suzuki 60-100 HP models from 1998–2007. Please review the 'Engine & Model Compatibility' table and cross-reference your OEM part number with our 'Part Number Matrix' to ensure a perfect match. If in doubt, compare our product images to your old part.
My Johnson/Evinrude model isn't listed, but the part number matches. Will it fit?
This kit is a known service equivalent for Johnson/Evinrude part 5031731. However, as specific model compatibility is not guaranteed, we strongly advise comparing your old parts to our product photos and specifications before ordering to ensure fitment.
What is the main difference between this aftermarket kit and an OEM part?
Our aftermarket kit is manufactured to meet or exceed OEM specifications using high-quality, corrosion-resistant materials. It offers comparable performance and durability to a genuine part, providing a reliable and cost-effective alternative.
Are any special tools required for installation?
Standard marine mechanic's tools, such as a socket set, are required to remove the lower unit and water pump housing. A torque wrench is recommended for reassembly to ensure bolts are tightened to the correct specifications.

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.
