Abstract
An improved flow control mechanism for a tilt and trim adjustment systern quickens tilt operation of an associated outboard drive, without sacrificing a desired control when trimming the outboard drive. The flow control mechanism includes a bypass line that interconnects the two sides of a respective tilt and trim cylinder. A bypass valve regulates flow through the bypass line. The bypass valve opens the bypass line when moving the outboard drive within the tilt range to quicken this operation. When moving the outboard drive within the trim range, however, the bypass valve closes the bypass line and connects an up chamber of the cylinder to a suction side of the pump to slow the speed at which the tilt and trim adjustment systern moves the outboard drive within this range of movement. The slower speed by which the systern raises and lowers the outboard drive enhances the ability to control the adjustment of the outboard drive's trim position. An actuator mechanism automatically controls the valve depending upon whether the drive's movement occurs within the tilt range or the trim range.
