GENINFO General information1-23 69J3D11Trim ram retraction functionWhen the outboard motor is tilted up and held in place with the tilt stop lever and the PTT switch ispressed to “DN,” the trim ram will be retracted.Although the gear pump attempts to draw oil from the tilt cylinder and trim cylinder lower chambers,after the PTT switch has been pressed, fluid cannot be drawn from the tilt cylinder lower chamberbecause the tilt ram is secured in place by the tilt stop lever. Only the PTT fluid from the trim cylinderlower chamber can be drawn, and as the fluid pressure decreases, the trim ram retracts into the trimcylinder. Since the tilt ram is secured in place, the PTT fluid pumped by the gear pump flows into thetilt cylinder upper chamber to increase fluid pressure. As a result, the down-relief valve opens, andthe PTT fluid is released into the reservoir.1 Tilt ram2 Tilt cylinder3 Trim ram4 Trim cylinder5 Gear pump6 Reservoir7 Down-relief valveÈ ReturnÉ Send:: S69J1430
