1. Prepare drive for installation by lowering the drive(s) to a level attitude, then remove steering rams at the back cap. Swing the rams to the side out of your way. Ensure that hydraulic lines are not kinked or damaged when swinging the rams. On multi engine boats, remove the tie bar.
2. Swing the drive to the left (port) to expose the gimble ring pivot pin.
3. Mount pivot pin bracket temporarily with supplied bolt. Only tighten the bolt snug, it will be removed later for final installation.
4. By hand, swing drive left and right to ensure bracket does not contact any part of transom housing or steering ram mount bolts.
5. Remove center and lower nut on the right (starboard) side of
the drive. Leave the washers on the studs. Install lower
bracket on studs and secure with nuts.
IMPORTANT There must be a washer between the drive and the bracket for proper alignment.
6. See picture on following page for visual reference.

,,
Alignment
1. Due to slight variations in brackets, castings, and machining, it is important to adjust the alignment of the sender arm with the upper bracket. The goal is to align the forked plastic sender arm with the upper bracket. Perfect alignment prevents premature wear and ensures proper function. In the picture below, you can see the upper bracket needs to bend inwards slightly to align it with the slot in the lastic arm.

2. Bend the upper bracket inwards or outwards to achieve perfect alignment. In the example below, a few gentle taps with a soft facet mallet brings the bracket into alignment.

,,
FINAL ASSEMBLY
1. The pivot pin needs to installed from the inside out so the cotter pin is on the outside. To do this, you will need to remove the upper bracket and the sender from the lower bracket.
2. To remove the sender, unscrew the two Philips screws. Don’t lose the lock washers or bent sheet metal retainers.
3. With the sender removed, connect the plastic arm to the upper bracket with the cotter pin and secure with the washer and cotter pin. See picture below.
4. Reinstall sender on to lower mount. Reinstall upper mount, using Loctite on the bolt threads.

,
5. Reinstall steering rams and tie bar. Secure sender wires to ram hoses as shown in the picture below. It is important to give the wire enough slack so the drive(s) can move fully left and right without binding or pulling the wires.

WIRING AND ADJUSTMENT
1. To get the wires through the transom you can reuse the slot in the transom and cable cover to pass the wires through the tra nsom. You will have to cut the wires off the sending unit below the molded on white seal and add wires to extend through the transom. Ensure your splices are water tight, we suggest soldering the wires together and sealing with a marine grade heat shrink tube. The wires passed through the old cable hole in the transom should be sealed with silicone like the cable was.
2. Wiring up the indicator. The three wires out of the sender are:
Wire “A” = Red = 5+ volt Wire “B” = White = Signal wire Wire “C” = Blue = Ground
