The Honda 91212-PNC-004 Oil Seal (43X58X7) is a genuine OEM component designed for BF115, BF135, BF140, and BF150 outboard motors. As a direct Honda OEM part, this seal is manufactured to the exact dimensions and tolerances specified for these outboards, ensuring a proper fit without modification. Verify your motor's serial number against the fitment table before ordering, as Honda supersedes parts at production breaks and the correct seal depends on your specific serial range. When a seal of this size fails, oil loss and contamination follow quickly, so sourcing the correct OEM replacement is essential to keeping the motor running cleanly.
Key Features
- Correct Sealing Dimensions — at 43 mm inner diameter, 58 mm outer diameter, and 7 mm width, this seal matches the exact bore and shaft dimensions Honda specifies for these outboard applications
- Genuine Honda OEM Part — sourced directly from Honda, part number 91212-PNC-004 meets the same specifications as the seal installed at the factory
- Outboard Motor Fitment — listed for BF115, BF135, BF140, and BF150 Honda outboard motors; confirm your serial number against the fitment table to ensure this is the correct seal for your production run
- Leak Prevention — a worn or damaged seal of this type allows oil to escape the gearcase or powerhead, leading to lubrication loss and internal damage if left unaddressed
An oil seal of this type creates a dynamic barrier between a rotating shaft and a fixed housing, retaining lubricant inside the gearcase or powerhead while preventing water and contaminants from entering. In an outboard motor operating in a saltwater or freshwater environment, maintaining that barrier is critical — once the seal wears or takes on a set, oil migrates out and water can migrate in, accelerating wear on the internal components the seal is meant to protect. Replacing a failed seal with the correct Honda OEM part restores that barrier to its original integrity.
