The Honda 90018-935-000 Head Bolt (8X94) is a genuine OEM fastener designed for Honda portable and outboard motors, including the B75, BF75, BF8, and BF100. As a factory-original component, this bolt is produced to Honda's exact specifications, giving you confidence that the fit and thread engagement will match what came off your motor. Verify your motor's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks.
Key Features
- Genuine OEM Head Fastener — sourced directly from Honda, this bolt meets the exact thread pitch, shank length, and head dimensions specified for these outboard motors, ensuring proper clamping load across the joint it secures
- Direct OEM Replacement — installs as a drop-in replacement with no modification, matching the original part number 90018-935-000 for straightforward service
- Broad Outboard Fitment — listed for Honda B75, BF75, BF8, and BF100 portable and outboard motors; confirm your serial number against the compatibility table to ensure this is the correct bolt for your specific unit
- Critical Clamping Integrity — a head bolt that is worn, stretched, or incorrectly torqued compromises the seal between mating surfaces, risking coolant or combustion leaks and potential engine damage; replacing with a genuine bolt restores the clamping integrity the motor depends on
A head bolt is a structural fastener that clamps cylinder head components tightly together, maintaining the compression seal between mating surfaces inside the outboard motor's powerhead. Proper clamping load across this joint is essential for combustion efficiency and for preventing coolant or water intrusion into areas it should not reach. A bolt that has been over-torqued, corroded, or stretched can no longer hold the correct load, and replacing it with a genuine Honda part ensures the joint is restored to its original specification.
