Thermal Valve
Thermal valve protects drive unit from excessive force that attempts to push down tilt rod when the outboard motor is at full
tilt up position.
The piston rod to which excessive force is applied is pressed into the cylinder, resulting in increasing hydraulic pressure in
the lower cylinder chamber over a rated value.
The increased hydraulic pressure reaches the thermal valve, resulting in opening the valve to dissipate itself.
