The Honda 91308-MJ0-003 O-Ring (49.4X3.1) is a genuine OEM sealing component designed for Honda outboard motors including the BF75, BF90, BF100, BF115, BF130, BF175, BF200, BF225, BF250, and BFP60. As a Honda OEM part, this O-Ring (49.4X3.1) is manufactured to the exact dimensions specified for these outboards, ensuring a proper seal without trimming or modification. Confirm your outboard's serial number against the fitment table before ordering, as Honda supersedes and revises sealing components at production breaks across a broad model range like this one.
Key Features
- Genuine OEM Sealing Integrity — manufactured to Honda's exact 49.4 x 3.1 mm dimensional specification, delivering the precise cross-section and diameter needed for a leak-free seal in marine applications.
- Direct OEM Replacement — replaces the original O-ring with no adaptation required; cross-reference part number 91308-MJ0-003 against your outboard's parts diagram to confirm placement before installation.
- Broad Outboard Fitment — listed for Honda BF75, BF90, BF100, BF115, BF130, BF175, BF200, BF225, BF250, and BFP60 outboard motors; verify your serial number against the fitment table to confirm applicability to your specific unit.
- Critical for Fluid Containment — a degraded or incorrectly sized O-ring allows fluid intrusion or leakage within the outboard, which can compromise performance and lead to more extensive internal damage if left unaddressed.
An O-ring is a loop-shaped seal that sits in a machined groove between two mating surfaces or around a shaft or fitting. When correctly installed and compressed, it forms a fluid-tight barrier that prevents oil, water, or other fluids from passing between those surfaces. In a marine outboard like the BF and BFP series, O-rings are used throughout the powerhead, gearcase, and cooling system to keep each fluid circuit isolated. When an O-ring ages, shrinks, or takes a set, it loses the compression needed to seal effectively — the result is a leak that can range from a minor weep to a significant loss of lubrication or coolant, depending on where the seal is located.
