Good To Know

Q: Does this seal match the OEM part number? A: Yes, it cross-references 6S5-81167-10-00, the same number used on the listed Yamaha 1800 engines. Always confirm your model and serial number before ordering.

Q: Should I replace other seals at the same time? A: It is common practice to inspect and replace seals together during a rebuild since access requires similar disassembly. Check the full seal set for your engine before starting the job.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
