SYSTEM DESCRIPTION
The power trim/tilt hydraulic system is completely contained between the outboard's stern brackets. The system consists of:
- Electric motor
- Oil reservoir
- Pump manifold assembly
- Cylinder body assembly
Optimal boat and outboard performance can be achieved by adjusting (trimming) the direction of outboard propeller thrust. The trim range (first 21°) is primarily made by the trim cylinders.
Outboard movement beyond the trim range is considered tilting. Tilting of the outboard may be desired in shallow water drive applications and trailering/storage. The tilt cylinder moves the out board through the tilt range (final 54°).
A tilt relief valve limits the propeller thrust load that will be supported by the unit in tilt range. As pres sure increases, the outboard will tilt down to the top of the trim range.
IMPORTANT: When in tilt range, make sure water is available to gearcase water pickups.
Manual Adjustment
The outboard can be manually raised or lowered through the entire trim and tilt range by opening the manual release valve a minimum of three turns. The manual release valve must be closed and torqued 45 to 55 in. lbs. (5 to 6 N·m) to hold the outboard in position and before normal operation can be resumed.

Trailering Bracket and Tilt Support
Use the trailering bracket to support the outboard when trailering in the tilted position. This bracket protects the hydraulic system from damage.
Tilt the outboard up fully, engage the bracket, then tilt the outboard down until the bracket is firmly in position.
- Trailering Bracket
For mooring or storing the boat with the outboard tilted, a tilt support is provided to support the outboard.
- Tilt support
IMPORTANT: The tilt support must not be used to support the outboard while trailering.
