2. To adjust the sensor’s angle relative to the hull, use the tapered plastic shim provided. If
the bracket has been temporarily fastened to the transom, remove it, Key the shim in
place on the back of the bracket.
2°-10° transom angle (stepped transom and jet boats): Position the shim with the
tapered end down.
19°-22° transom angle (small aluminum and fiberglass boats):
Position the shim with the tapered end up.
3. If the bracket has been temporarily fastened to the transom, remove it. Apply a marine
sealant to the threads of the two #10 x 1-1/4” self tapping screws to prevent water
seeping into the transom. Screw the bracket to the hull. Do not tighten the screws
completely at this time.
4. Repeat step 1 to ensure that the angle of the sensor is correct.
Note: Do not position the sensor farther into the water than necessary to avoid
increasing drag, spray, and water noise and reducing boat speed.
5. Using the vertical adjustment space on the bracket slots, slide the sensor up or down to
provide a projection of 3 mm (1/8”). Tighten the screws.
