- Verify Your Model — Honda supplies this washer across many BF variants; check your motor model against the compatibility table to confirm this is the correct part for your application
A plain washer distributes the clamping load of a fastener across a broader surface area, preventing the fastener head or nut from pulling through or damaging the component it secures. In an outboard motor — where components are exposed to the vibration of a running engine and the harsh marine environment — proper load distribution is essential to keeping assemblies tight and aligned through extended use. When a washer is missing, undersized, or deformed, fastener tension becomes uneven, which can lead to loosening, surface damage, or fastener failure over time.
