INFO

PTT (Power trim and tilt) unit

The PTT unit has been newly developed for the F225. Based on the field-proven 61A type, its PTT
fluid passage and internal valve construction have been changed for this application. Although the
valves of the 61A type have been distributed to the various areas of the gear pump housing, the
valves of the new PTT unit have been concentrated in the vicinity of the gear pump to improve their
serviceability. In addition, the material of the gear pump housing has been changed to enhance its
corrosion resistance.
