The Honda 91305-KC1-850 O-Ring (16.5X2.5) is a genuine OEM sealing component designed for BF115 and BF130 outboard motors. As a factory-sourced part, this O-Ring (16.5X2.5) is manufactured to Honda's original dimensions, ensuring a consistent, leak-free seal in the application it was designed for. Honda supersedes parts at serial breaks, so confirm the part number 91305-KC1-850 against your motor's serial number in the fitment table before ordering.
Key Features
- Genuine OEM Sealing Integrity — sourced directly from Honda, this O-ring meets the exact dimensional and material specifications of the original, ensuring the seal performs as intended in your outboard motor's sealing circuit
- Exact Dimensional Match — the 16.5X2.5 sizing is a precise specification; installing an incorrectly sized O-ring risks fluid leakage, so verify this size matches the location you are servicing
- Fits BF115 and BF130 Outboards — listed for Honda BF115 and BF130 outboard motors; confirm your motor's serial number against the fitment table to ensure this is the correct O-ring for your specific serial range
An O-ring is a circular elastomeric seal that sits in a machined groove, compressing against a mating surface to prevent fluid or pressure from escaping past a joint or fitting. In an outboard motor, O-rings are used throughout the engine and lower unit to seal oil passages, cooling water circuits, and fuel connections. When an O-ring degrades, cracks, or takes a permanent set, the seal is lost — allowing fluid to weep past the joint, which can lead to overheating, oil loss, or contamination depending on the circuit involved. Replacing a worn O-ring with a correctly sized genuine Honda part restores the original seal and protects the surrounding components from damage.
