Troubleshooting & FAQ
How do I know if this kit fits my Yamaha outboard?
This kit is designed for select Yamaha 4-Stroke models including the F75, F90, F100, F115, LF115, and VF115 from 2000–2017. Always verify your specific model and year against our compatibility table before ordering. Note that it does not fit the F80B (2005-2015), which requires a different kit (67F-W0078-00-00).
What are the signs of a failing water pump impeller?
Common symptoms include the engine overheating at idle or low speeds, a weak or non-existent water stream from the "tell-tale" outlet, and in some cases, a high-temperature alarm from your engine's monitoring system.
How often should I replace the water pump impeller?
For preventative maintenance, it is recommended to inspect the impeller annually and replace it every 1-2 years or every 100-200 hours of operation. Replacement intervals can vary based on usage conditions, particularly in saltwater or silty environments.
Can I replace just the impeller instead of the whole kit?
While you can replace only the impeller, this complete kit includes all necessary gaskets, O-rings, and hardware. Replacing all wear-and-tear components at once ensures a proper seal, prevents leaks, and restores optimal cooling performance, which is critical for engine health.
The kit includes parts I don’t think I need. Why?
This kit is designed to cover multiple model years and variations within the 75-115 HP range. It may include extra O-rings or bolts to ensure it services all compatible applications. Use only the components that match your specific unit's original parts.

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.
