The Honda 91333-PNA-003 O-Ring (15X1.9) is a genuine OEM replacement seal designed for a wide range of Honda outboard motors, including BF40, BF50, BF60, BF75, BF90, BF100, BF115, BF135, BF140, BF150, BF200, BF225, BF250, BF350, and BFP60 models. As a direct Honda OEM part, this O-ring is manufactured to the exact dimensions — 15 mm inner diameter, 1.9 mm cross-section — required for a proper seal in your motor. Confirm your outboard's serial number against the fitment table before ordering, as Honda updates parts at serial breaks across its extensive outboard lineup.
Key Features
- Exact OEM Dimensions — manufactured to Honda's specified 15 x 1.9 mm profile, ensuring the sealing cross-section and diameter match the original groove geometry in your outboard
- Genuine Honda OEM Part — sourced directly from Honda, carrying part number 91333-PNA-003, so you're replacing a worn seal with the same component Honda installed at the factory
- Broad Outboard Fitment — listed for Honda outboard motors including BF40, BF115, BF150, BF250, BF350, BFP60, and more; always verify your serial number against the compatibility table to confirm the correct application
- Maintains a Leak-Free System — a degraded or improperly sized O-ring allows fluid to bypass the sealing point; replacing it with the correct-dimension part restores a proper seal and protects surrounding components
An O-ring is a loop-shaped sealing element seated in a machined groove to prevent fluid or pressure from passing between two joined components. In Honda outboard motors, O-rings appear throughout the cooling, lubrication, and fuel systems, where a secure seal is essential to keep fluids where they belong and out of areas where they can cause damage. When an O-ring hardens, cracks, or is compressed beyond its service life, the seal fails — leading to leaks, contamination, or loss of system pressure that can affect outboard performance and longevity.
