The Honda 91331-PC9-003 O-Ring (21.2X2.4) is a genuine OEM sealing component designed for BF60 and BFP60 outboard motors and GXV50 and GXV57 vertical shaft engines. As a direct Honda OEM part, this o-ring is manufactured to the exact dimensions and material specification Honda requires for the sealing applications it serves. Confirm your unit's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and this listing covers specific production ranges across these models.
Key Features
- Genuine OEM Sealing Integrity — manufactured to Honda's exact dimensional spec (21.2 x 2.4 mm) so the sealing contact area is correct from the moment this o-ring is installed
- Cross-Platform Fitment — listed for BF60 and BFP60 outboard motors as well as GXV50 and GXV57 vertical shaft engines; verify your serial number against the fitment table to confirm the correct application
- Leak Prevention — a correctly sized, undamaged o-ring maintains a fluid-tight seal in its bore; a cracked, compressed, or swollen o-ring allows fluid seepage that can lead to low fluid levels and operational issues over time
An o-ring is a circular elastomeric seal seated in a machined groove. When assembled, it is compressed slightly between two mating surfaces or within a bore, forming a continuous barrier that prevents fluid or gas from passing the joint. Over time, heat cycling, chemical exposure, and compression set cause the material to harden, crack, or deform, breaking the seal. Replacing a worn o-ring with a correctly dimensioned Honda OEM part restores the original sealing geometry and prevents leaks that would otherwise compromise fluid levels or pressure within the assembly.
