Engine Compatibility
This seal appears across a very broad range of Mercury and MerCruiser applications, including many classic Mercury outboards and older Bravo / Bravo Two / Bravo Three drive families in dealer "Where Used" listings. Because the fitment range is so broad, exact compatibility should always be confirmed by model and serial number before ordering.
Serial Number Fitment Notice
Please confirm compatibility in the Mercury Parts Catalog using your exact engine or drive serial number before purchase. Mercury's official catalog is organized by model and serial number for accurate parts lookup.
When This Part Needs Replacement
Replace this seal when the original is hardened, damaged, leaking, or being renewed during cooling-system or water outlet tube service. That service context is based on seller descriptions that identify 26-36556 as a water outlet tube seal.
Installation Notes
Install only the exact seal specified for the application being serviced. Small OEM seals can look interchangeable, but diameter and application location matter, so matching by part number and serial-based diagram is the safest approach.

Parts Desk Insight
Small cooling-system seals are easy to overlook, but they are often the difference between a dry, reliable assembly and a nuisance leak. Matching the exact OEM seal is the smart move anytime the tube or housing is already apart. This is a practical service inference based on the part's seal function and common water-outlet application descriptions.
