TRIM AND TILT SYSTEM DESCRIPTION SYSTEM DESCRIPTION Trailering Bracket and Tilt Support The power trim/tilt hydraulic system is completely Use the trailering bracket to support the outboard contained between the outboard's stern brackets. when trailering in the tilted position. This bracket The system consists of: protects the hydraulic system from damage.
Page 318: Modes Of Operation
TRIM AND TILT MODES OF OPERATION MODES OF OPERATION The trim/tilt hydraulic assembly achieves trim and tilt movement through the following modes of operation. Trim-OUT / Tilt-UP Mode When the UP switch is pressed, the trim/tilt motor rotates clockwise (as viewed from pump end) and turns the pump gears.
Page 319: Tilt-Down / Trim-In Mode
TRIM AND TILT MODES OF OPERATION Tilt-DOWN / Trim-IN Mode When the DOWN switch is pressed, the trim/tilt motor rotates counterclockwise (as viewed from pump end) and turns the pump gears. Fluid pressure passes through the DOWN shuttle valve to the UP shuttle valve, which mechanically opens the UP check valve.
Page 320: Impact Relief
TRIM AND TILT MODES OF OPERATION Impact Relief Should the gearcase hit an underwater object and the outboard suddenly tilts up, the tilt cylinder extends. The fluid above the piston is com- pressed, producing high pressure. This high pressure fluid passes through the impact relief valves in the tilt piston, dissipating much of the energy of the impact.
Page 321: Shallow Water Drive Tilt Relief
TRIM AND TILT MODES OF OPERATION Shallow Water Drive Tilt Relief If the outboard exceeds idle RPM while operating in shallow water drive mode (tilted up beyond the trim range), increased pressure beneath the tilt piston forces fluid through the tilt relief valve built into the manual release valve.
Page 322: Manual Release - Up
TRIM AND TILT MODES OF OPERATION Manual Release – UP The outboard can be positioned manually by first opening (loosening) the manual release valve. Open the manual release valve (turn it slowly counterclockwise) with a screwdriver, about 3 1/2 turns, until it lightly contacts its retaining ring. 001988 1.
Page 323: Manual Release - Down
TRIM AND TILT MODES OF OPERATION Manual Release – DOWN When the manual release valve is opened and the outboard is manually tilted down or trimmed in, fluid flows from the bottom of the tilt cylinder (in the tilt range), or from the bottom of all of the cylin- ders (in the trim range), and past the manual release valve.
