Page 306: Trim Up
Trim Up When the trim switch is activated in the “up” position, the electric motor (c) begins to rotate the pump gears (j), the oil pump draws a small amount of oil through the filter (g) and through the up circuit suction port (i). The oil pump gear (j) rotation forces oil into the pas- sages for the up circuit.

Page 308: Tilt Up
Tilt Up In the “up” mode, as the piston rod (a) extends from the cylinder (w), the memory piston (t) clears or un- covers the pressure relief passage. Oil from the up cavity will enter this passage and, if required, causes the tilt relief piston (s) to open the tilt pressure relief valve (r).

Page 310 Maximum Tilt With the piston rod at maximum travel, and due to no rod movement, the pressure inside of the trim cylin- der (w) will increase to the pressure required to move the tilt relief piston (s). The tilt relief piston’s “pin” opens the tilt relief valve (r).

Page 312: Down Mode
Down Mode When the trim switch is activated in the “down” posi- tion, the electric motor (c) will rotate the pump (j) in the opposite direction. With the pump gears rotating backwards, the flow of oil is reversed. Oil is drawn through the filter (g), through the down circuit suction port (k) and into the oil pump (j).

Page 318: Manual Tilt
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.
