Key Features
- Genuine OEM Specification — manufactured by Honda to the same tolerances used at the factory, ensuring the locking function during valve clearance adjustment is maintained correctly
- Direct Service Replacement — this nut installs as part of the valve adjustment procedure with no rework needed, preserving proper tappet clearance across the valvetrain
- Broad Outboard Fitment — listed for Honda outboard motors including the BF75, BF115, BF150, BF200, BF250, and BF350, among others
- Verify Your Serial Number — Honda supersedes parts at production breaks; check your outboard's serial number against the fitment table to confirm this is the correct nut for your motor
The tappet adjusting nut locks the valve clearance setting in place once the correct gap has been set between the rocker arm and the valve stem. On Honda four-stroke outboard motors, maintaining precise valve clearance is essential for smooth combustion, full power output, and long engine life. When this nut loosens or becomes damaged, the valve clearance can shift out of spec, leading to rough running, hard starting, or accelerated wear on the valvetrain components.
