The Honda 90031-PV0-305 Bolt-Washer (10X30) is a genuine OEM fastener designed for BF75, BF90, and BF100 outboard motors. As a factory-original component, this bolt-washer is sourced directly from Honda and built to the same specifications as the hardware installed during original assembly. It is listed for the BF75, BF90, and BF100 — confirm your serial number against the fitment table before ordering to ensure this is the correct part for your motor. When it comes to hardware on a marine outboard, using the exact OEM part keeps critical joints properly torqued and prevents the loosening or leakage that an incorrect fastener can cause.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, matching the original bolt-washer specification for consistent clamping force and thread engagement in your outboard.
- Integrated Washer Design — the captive washer distributes load evenly across the mating surface, reducing the risk of surface damage or fastener backing out under vibration.
- Outboard Fitment — listed for BF75, BF90, and BF100 outboard motors; verify your motor's serial number against the compatibility table to confirm the correct application.
- Serial Number Matters — Honda supersedes hardware at production breaks, so always match your serial number to the fitment table before ordering.
A bolt-washer is a fastener that combines a bolt and a washer into a single integrated unit. In an outboard motor, fasteners like this are used throughout the powerhead, gearcase, and ancillary assemblies to secure covers, brackets, and components that must remain firmly in place under the demanding conditions of marine operation — vibration, thermal cycling, and exposure to water. Using the correct OEM fastener ensures proper thread fit and clamping load; an incorrect or worn fastener can allow joints to work loose, leading to leaks, misalignment, or component damage that is far more costly to address than replacing the hardware itself.
