Key Features
- Genuine Honda OEM — sourced directly from Honda, ensuring the 10mm washer meets the same dimensional standards as the original hardware it replaces
- Broad Outboard Coverage — listed for Honda portable and standard outboard motors including B75, BF8, BF9, BF15, BF20, BF75, BF100, BFP8, BFP9, BFP15, and BFP20
- Serial Number Verification Advised — Honda updates hardware across production runs, so confirm your motor's serial number against the fitment table to ensure this is the correct washer for your unit
A washer is a flat hardware component that distributes the clamping load of a fastener across a wider surface area, protecting the mating material and helping the fastener maintain consistent holding force. On outboard motors, correctly sized washers are critical to keeping assemblies properly torqued in the demanding marine environment — vibration, water exposure, and repeated thermal cycling all work to loosen fasteners over time. Using a washer with the correct outer diameter, inner diameter, and thickness, such as part number 90513-921-000, ensures the fastener assembly performs as Honda designed it to.
