The Honda 90406-KV3-780 Washer (6MM) is a genuine OEM replacement designed for BF75, BF90, BF115, and BF130 outboard motors. As a Honda OEM component, this washer is manufactured to the exact dimensions Honda specifies, ensuring it seats and functions correctly in your outboard. Confirm your motor's serial number against the fitment table before ordering, as Honda updates part specifications at serial breaks and this listing covers specific production ranges.
Key Features
- Genuine OEM Specification — sourced directly from Honda, this 6MM washer matches the original dimensions and tolerances Honda engineered into these outboards, ensuring correct load distribution and seating.
- Direct OEM Replacement — replaces the original washer with no modification required to the fastener assembly it supports, keeping your outboard's hardware stack correct.
- Broad Outboard Fitment — listed for Honda BF75, BF90, BF115, and BF130 outboard motors; verify your serial number against the fitment table to confirm the correct part for your unit.
- Serial-Range Awareness — Honda revises hardware specifications at production serial breaks, so always cross-check your motor's serial number with the compatibility table before finalizing your order.
A washer distributes the clamping load of a fastener across a broader surface area, preventing the bolt head or nut from pulling into or damaging the material it secures. In an outboard motor environment, where vibration, water exposure, and repeated service cycles are constant factors, using the correct OEM washer ensures the fastener assembly maintains proper clamp force over time. A washer of the wrong diameter or thickness can allow a fastener to work loose or bear unevenly, compromising the integrity of the joint it holds.
