The Honda 91212-PWA-003 Oil Seal (40X55X7) is a genuine OEM replacement designed for BF75, BF90, and BF100 outboard motors. As a direct Honda OEM part, it is manufactured to the same specifications as the original, ensuring a correct fit within the sealing circuit of your outboard. This seal is listed for the BF75, BF90, and BF100 — confirm your motor's serial number against the fitment table before ordering to ensure you have the right part for your specific unit.
Key Features
- Genuine Honda OEM Sealing — manufactured to the original dimensional specification (40 x 55 x 7 mm), maintaining the interference fit and sealing lip geometry required to prevent oil loss in Honda outboard applications.
- Direct OEM Replacement — sourced directly from Honda, this seal installs in place of the original with no reworking required, restoring the oil retention performance Honda engineered into these motors.
- Covers BF75, BF90, and BF100 Outboards — listed for Honda's BF75, BF90, and BF100 outboard motors; always match your motor's serial number to the fitment table to confirm applicability before installation.
- Serial Number Verification Recommended — Honda supersedes and revises parts at production breaks, so checking your motor's serial number against the compatibility table is the surest way to confirm this is the correct seal for your unit.
- Prevents Damaging Oil Loss — a degraded or leaking oil seal allows lubricant to escape, leading to oil contamination in areas where it does not belong and potential internal damage from insufficient lubrication; replacing it on schedule protects the motor's internals.
An oil seal is a precision-formed ring that retains lubricating oil within a rotating or reciprocating assembly while keeping water, debris, and contaminants out. In an outboard motor, oil seals are found at critical junctions — including the crankshaft, gearcase, and drive shaft areas — where rotating components pass through housings exposed to the marine environment. When an oil seal hardens, cracks, or loses its sealing lip integrity through age or wear, it allows oil to escape and water to enter, which can cause accelerated wear or serious internal damage if not addressed promptly.
