Manual Tilt
To manually tilt the outboard engine, the owner will need to back out the manual release
valve (j). With the valve backed out, the internal passages inside the manifold are connected
together. These passages connect both the cylinder down and up cavities together, along
with the reservoir (t), allowing the engine to be raised or lowered. Trim rod (b) movement
will continue until the manual release valve is closed, locking the fluid inside of the cylinder
and manifold.
