The Honda 90512-921-010 Washer (6MM) is a genuine OEM replacement designed for an extensive range of Honda outboard motors and horizontal shaft engines. As a factory-sourced component, this washer is produced to Honda's exact dimensional specifications, ensuring it seats and functions the way the original was designed to. This part is listed across a broad range of models — including BF2, BF115, BF250, G65, and GS65 — and buyers should verify their serial number against the fitment table to confirm the correct application for their unit.
Key Features
- Genuine OEM Sourcing — sourced directly from Honda, this washer meets the exact dimensional and material standards of the original part it replaces
- Wide Fitment Coverage — listed for Honda outboard motors ranging from portable models such as the BF2 and BF5 through full-size units including the BF150, BF200, and BF250, as well as G65 and GS65 horizontal shaft engines
- Serial Number Verification Recommended — Honda supersedes parts at production breaks, so check your engine or motor serial number against the fitment table before ordering to confirm this is the right washer for your unit
A washer of this size serves as a load-distributing component used at fastener and assembly points throughout an outboard motor or engine. By spreading clamping force across a broader surface area, it prevents fastener heads or nuts from pulling through or damaging the mating surface during assembly. When a washer is worn, missing, or the wrong size, fasteners can loosen under vibration or the seating surface can be damaged — affecting the integrity of the assembly it secures.
