The Honda 91317-PA9-003 O-Ring (33.2X2.4) is a genuine OEM sealing component designed for BF115, BF135, BF140, and BF150 outboard motors. As a direct Honda OEM part, it is manufactured to the exact dimensional tolerances required for a proper seal in its designated application. Confirm your outboard's serial number against the fitment table before ordering, as Honda supersedes parts at specific serial breaks and this listing may cover multiple serial ranges.
Key Features
- OEM Sealing Integrity — manufactured to Honda's exact 33.2 x 2.4 mm profile, ensuring the compression and contact geometry needed for a leak-free seal in marine service.
- Genuine Honda Part — sourced directly from Honda, with part number 91317-PA9-003 matching Honda's own parts catalog for the BF115, BF135, BF140, and BF150 outboard motor lines.
- Broad Outboard Coverage — listed for BF115, BF135, BF140, and BF150 outboards; confirm your serial number against the fitment table to ensure this is the correct O-ring for your specific unit.
- Leak Prevention — a degraded or worn O-ring allows fluid intrusion or loss at the sealed joint, which in a marine environment can lead to water ingestion or fluid contamination and compromise outboard performance.
An O-ring is a round-section sealing loop seated in a machined groove between two mating surfaces. When the joint is assembled and torqued, the O-ring compresses against both surfaces, creating a fluid-tight barrier that prevents leakage in either direction. In outboard motor applications, O-rings are used throughout the powerhead, lower unit, and cooling circuit, and even minor degradation — from heat, age, or chemical exposure — can allow seawater ingestion or fluid loss that quietly damages internal components over time. Replacing a failed O-ring with a correctly sized genuine Honda part restores the seal to its original specification and protects the components it serves.
