The Honda 90118-HW1-671 Flange Bolt (8X28) is a genuine OEM replacement fastener designed for Honda outboard motors including the BF25, BF30, BF40, BF50, BF60, BF75, BF90, BF100, and BFP60. As a factory-original component, this bolt is manufactured to Honda's exact dimensional specifications, so it threads and seats correctly without any guesswork. Honda supersedes hardware at serial breaks, so confirm part number 90118-HW1-671 against your outboard's serial number in the fitment table before ordering.
Key Features
- Genuine OEM Fastener — sourced directly from Honda, so thread pitch, shank diameter, and flange geometry match the original hardware exactly as it left the factory
- Integrated Flange Design — the built-in flange distributes clamping load across a wider bearing surface, reducing the risk of fastener pull-through or loosening in the demanding marine environment
- Broad Outboard Fitment — listed for Honda BF25, BF30, BF40, BF50, BF60, BF75, BF90, BF100, and BFP60 outboard motors; verify your serial number against the fitment table to confirm the correct application
- Critical Torque Retention — a correctly torqued OEM flange bolt holds assemblies securely through the vibration and load cycles that outboard operation generates; a worn, stripped, or incorrect fastener compromises joint integrity
A flange bolt combines a standard hex bolt with an integrated washer-style flange at the base of the head. On Honda outboard motors, flange bolts are used throughout the powerhead, midsection, and lower unit assemblies where a broad clamping surface and vibration resistance are essential. When a fastener is stripped, corroded, or missing, the joint it secures can shift or work loose, leading to misalignment, fluid leaks, or component damage that interrupts time on the water.
