How to Install Trim Switches on Quicksilver Boats

The Quicksilver manual, three-button, manual, trim control switch is linked to the auto-trim function of the trim-and-tilt system. The manual, three-button system is unique to the Quicksilver stern drive unit and comes in two forms. One -- the Auto Trim system -- has no adjustment knob to fine tune trim. The other, Auto Trim II, has a knob through which you can fine tune the motor's trim to achieve the optimum performance.
