The Honda 12391-881-000 Head Cover Gasket is a genuine OEM component designed for BF75, BF100, and BF8 outboard motors. As an authentic Honda part, it is manufactured to the same specifications as the original, ensuring a correct seal between the head cover and the engine. This gasket is a direct-fit replacement for the units listed in the fitment table — always verify your outboard's serial number before ordering, as Honda supersedes parts at serial breaks.
Key Features
- OEM Sealing Integrity — produced to Honda's original specifications, delivering the precise clamping and compression seal that keeps oil inside the head cover and away from external surfaces
- Exact OEM Replacement — engineered to match the original gasket geometry for a direct, no-guesswork installation on BF75, BF100, and BF8 outboard motors
- Serial Number Verification Recommended — Honda revises parts at production serial breaks, so confirm your outboard's serial number against the fitment table to ensure you have the correct version
- Leak Prevention — a deteriorated or damaged head cover gasket allows oil to seep past the cover joint; replacing it with a genuine Honda gasket restores a proper seal and keeps the engine running cleanly
The head cover gasket sits between the valve or cam cover and the top of the engine, forming a compressed seal that prevents oil from escaping around the cover joint. Over time, heat cycling and vibration cause the original gasket to harden, compress, or crack, which allows oil to seep out and collect on the exterior of the engine. Replacing a failed gasket promptly stops oil loss, prevents contamination of surrounding components, and keeps the outboard operating cleanly through its working life.
