64E-43860-01 – Manual Valve – Yamaha

The 64e4386001 manual valve is a genuine Yamaha outboard OEM valve sub-assembly that provides precise manual control in your trim and tilt system. This valve plays a key role in the hydraulic trim/tilt circuit by allowing you to manually release or hold fluid pressure when adjusting the engine’s tilt angle. It fits Yamaha power trim & tilt assemblies where hydraulic control is required.

This manual valve lets you safely lower or raise the outboard motor without relying only on electric or hydraulic pressure. In many cases, a worn or seized valve can make trim adjustments sluggish or difficult. When you install a fresh 64e4386001 manual valve, you restore smooth, controlled trim/tilt movement. Moreover, this valve helps protect your hydraulic system from pressure spikes and helps lock the system in place when needed.

Also, because this is a genuine Yamaha part, it matches the factory specifications exactly. You won’t have to guess on fitment or make modifications. Simply remove the old valve and replace it with this OEM unit for proper manual control. Furthermore, this valve performs reliably in both freshwater and saltwater environments when maintained properly.

This manual valve sub-assembly works especially well during routine service or when rebuilding hydraulic components. It provides positive engagement and consistent manual release performance over time. For boat owners who want dependable trim and tilt control, this genuine Yamaha valve delivers lasting reliability.
