HYDRODRIVE - MBY4 bypass Valve (inbaord application)
This bypass valve is used with inboard system for safety purposes. It mounts near the cylinder and bypasses it in case the pump fails, allowing you to move the cylinder (rudder) by hand. In some countries it is an obligation to have it installed.
Also included is a 2.00m twin hose kit with pre-installed fittings for easy installation.
