IMCO GIMBAL / SCX 3 WIRE MERC SENDER

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 On multi engine boats, remove the tie bar.

2. Swing the drive to the left (port) to expose the gimble ring pivot

3. Mount pivot pin bracket temporarily with supplied bolt. Only tighten the bolt snug, it will be removed later for final

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

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
2. To remove the sender, unscrew the two Philips screws. Don’t lose the lock washers or bent sheet metal
3. With the sender removed, connect the plastic arm to the upper bracket with the cotter pin and secure with the washer and cotter 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
2. Wiring up the The three wires out of the sender are:

Wire “A” = Red = 5+ volt
Wire “B” = White = Signal wire Wire “C” = Blue = Ground

Installation

1. Tape the connector end of the new sensor harness to the cut end of the old harness.
2. Pull the new harness through the gimbal housing using the old harness.
3. Remove and discard the old harness from the new harness.
4. Position the two grommet halves attached to the sensor wires with the seam vertically aligned and seat them in the gimbal housing grommet hole. Maintain light tension on the wires from inside the boat to hold the grommets in place.
   d. Push the retaining clip onto the terminal connector block until it snaps into place over the locking tabs located on either side of the terminal connector block.
   

9. Connect the trim position sensor connector to the transom harness connector.

_A~justing the Trim Position Sensor on Gasoline Engines

Adjusting the Trim Position Sensor on DTS Engines

1. Before connecting the CDS, turn the ignition key to the “ON” position.
2. Since no limits have been set yet, position an observer at the rear of the boat to make sure the sterndrive will not make contact with the swim platform or ground during this test.
3. Trim drive fully up and down as far as mechanically possible without allowing the drive to contact any obstacles or until the drive reaches the mechanical limits of travel one complete cycle. Do not make contact with the swim platform while trailering up, and do not make contact with the ground trimming in.
4. Once the cycle is complete, key off and move the control lever to reverse wide open throttle for 10 seconds to completely power down the PCM.
5. Connect the CDS to the engine diagnostic connector.
6. Turn the ignition key to the “ON” position.
7. Select the appropriate engine set-up on the CDS.
8. Select “Tool Box” and go to the “Data List” screen.  Page 4

Setting Trailer Limit on DTS Engines
IMPORTANT: Incorrectly configuring the trim limlt using the CDS can create a programming error in the engine’s PCM. Always set the trailer limlt before setting the trim limlt. If you configure the trailer limlt incorrectly, contact the Mercury Marine Technical
Service Department for further instructions.
Trailer limit settings establish the maximum trailer up position of the sterndrive to prevent stemdrlve to boat contact or damage.
Setting Trailer Limit
IMPORTANT: Set the trailer limit before the trim llmlt.
1. Go to the “Active Diagnostics” screen and select “Trailer Limit.” When you click “Run” a red window will appear. Select “Proceed.”

A blue screen will appear. Follow the instructions and trim the drive fully in, operating the pump for 3 seconds after the mechanical limit has been reached. Click “OK” to continue.
Trim the drive to full up trailer position, ensuring there is clearance between the drive and the swim platform. The trailer position at the top may not read the full 100% on the CDS due to the celery stick position. Click “OK” to continue.
A blue screen will appear. Follow the instructions on the screen. Turn the ignition key to the “OFF” position and move the remote lever to the reverse, wide open throttle position for 10 seconds to store the new values in the ECM. Click OK to continue.
