Yamaha Motor Co 6E5-43802-00-00 Valve Sub Assembly

The Yamaha 6E5-43802-00-00 Valve Sub Assembly is a genuine Yamaha fluid-control component designed for marine outboard trim and tilt hydraulic systems. This valve sub assembly regulates hydraulic fluid flow and pressure within the trim unit, enabling precise control of engine tilt and keeping the trim position smooth and stable under typical sea conditions. Installed in Yamaha outboard engines, it serves as a key repair or replacement part for malfunctioning hydraulic valve systems and is mounted inside the hydraulic trim and tilt unit. The component uses a precision-machined metal valve body and is manufactured in Japan as an OEM Yamaha replacement, with model-specific compatibility required for correct fitment. Common related replacements include Yamaha 6E5-43802-01-00, 64E-43802-00-00, and 67F-43802-01-00, providing options within the same trim/tilt valve family. With direct mounting in the hydraulic trim and tilt unit, it supports reliable engine positioning—from small tilt changes to full trim adjustments—ensuring consistent response in challenging marine environments.
