Honda 91214-RNB-A01 Oil Seal (80X98X10)

The Honda 91214-RNB-A01 Oil Seal (80X98X10) is a genuine OEM component designed for Honda BF-series outboard motors, including the BF75, BF90, BF100, BF115, BF135, BF140, BF150, BF175, BF200, BF225, and BF250. Sourced directly from Honda, this oil seal carries the exact dimensions and material specification Honda engineers specified for these outboards. Confirm the part number 91214-RNB-A01 against your motor's serial number using the fitment table before ordering, as Honda periodically supersedes seals at production breaks.

Key Features

• Genuine OEM Sealing Integrity — manufactured to Honda's exact dimensional tolerances for the 80 mm bore, 98 mm outer diameter, and 10 mm width, ensuring proper fluid retention without leakage at the sealing lip

• Serial Number Verification Recommended — Honda supersedes seals at specific production breaks, so cross-check your motor's serial number against the fitment table to confirm this is the correct seal for your unit

An oil seal prevents lubricating oil from escaping a rotating shaft assembly while blocking water and contaminants from entering the housing. In a Honda outboard motor, oil seals are critical to keeping gear oil contained within the gearcase and protecting internal components from the corrosive marine environment. When an oil seal wears, cracks, or loses its sealing lip tension, gear oil leaks out and water can migrate in — leading to accelerated gear and bearing wear that can result in costly gearcase damage if left unaddressed.
