The Honda 94101-04200 Plain Washer (4MM) is a genuine OEM component used across a wide range of Honda equipment, including BF2, BF9, BF15, and BF20 portable outboard motors, E300, EM400, and ER400 generators, and GXV50 and GXV57 vertical shaft engines. As a genuine Honda part, it is manufactured to the exact dimensions Honda specifies, ensuring correct clamping and retention in the assemblies it serves. Always confirm the part number 94101-04200 against your machine's parts diagram before ordering, as Honda uses similar hardware across many models and a dimension mismatch can cause improper fastener seating.
Key Features
- Genuine OEM Dimensional Accuracy — sourced directly from Honda, this 4MM washer meets the exact thickness and inner-diameter tolerances specified for each application, ensuring consistent load distribution under the fastener head
- Broad Cross-Equipment Fitment — listed for BF-series portable outboard motors, Honda generators including the E300, EM400, and ER400, and GXV50 and GXV57 vertical shaft engines
- Verify Before Installing — Honda uses similar plain washers across many assemblies; confirm part number 94101-04200 against your machine's official Honda parts diagram to ensure the correct size for your specific application
A plain washer distributes the clamping load of a fastener across a broader surface area, protecting the mating component from damage and helping the fastener maintain its holding force over time. In equipment that sees vibration — such as outboard motors operating on the water, portable generators under load, or small vertical shaft engines — correct washer sizing is essential to keep fasteners from loosening or pulling through. Using an undersized or oversized washer can lead to uneven clamping, fastener loosening, or surface damage to the components being joined.
