Manual Tilt
To manually tilt the outboard engine, the owner will
need to back out the manual release valve (p) 3-4
turns. With the valve backed out, the internal pas-
sages inside the manifold are connected together.
These passages connect both the cylinder down and
up cavities together, along with the reservoir, allow-
ing the engine to be raised or lowered. Piston rod (a)
movement will continue until the manual release
valve (p) is closed, locking the fluid inside of the cylin-
der and manifold.
