The Honda 90206-ML7-000 Tappet Adjusting Nut is a genuine OEM component designed for Honda BF35, BF40, BF45, BF50, BF75, and BF90 outboard motors. As a direct Honda OEM part, it is manufactured to the exact specification required for proper valve adjustment on these outboards. Confirm your motor's serial number against the fitment table before ordering, as Honda supersedes parts at defined serial breaks across this range. This nut is the correct choice when servicing the valvetrain on any of the covered models.
Key Features
- Genuine OEM Valve Hardware — sourced directly from Honda, this nut meets the precise dimensional and thread requirements needed for accurate tappet clearance adjustment on your outboard's valvetrain
- Direct-Fit Replacement — engineered to install exactly as the original, with no rework needed to seat and torque correctly during a valve adjustment service
- Broad Outboard Coverage — listed for Honda BF35, BF40, BF45, BF50, BF75, and BF90 outboard motors; check your serial number against the fitment table to confirm the correct part for your specific unit
- Valvetrain Accuracy — a correctly sized and threaded adjusting nut holds tappet clearance at the set value; a worn or imprecise nut allows clearance to drift, leading to noisy valve operation or reduced engine performance
The tappet adjusting nut is a critical piece of hardware in the valve clearance adjustment process on Honda four-stroke outboard motors. During a valve service, the nut locks the rocker arm adjusting screw in position once the correct tappet clearance has been set, holding that gap stable through the heat and vibration of normal operation. When this nut is worn, cross-threaded, or loses its ability to hold the screw firmly, valve clearance can drift out of specification — resulting in symptoms such as valve noise, hard starting, or a loss of power on the water.
