1. MOUNTING
1-15
4. If you know your transom angle, the bracket is designed for a standard 13°
transom angle.
11°-18° angle: No shim is required. Skip to step 3 in "Adjustments".
Other angles: The shim is required. Skip to step 2 of "Adjustments".
If you do not know the transom angle, temporarily attach the bracket and sensor
to the transom to determine if the plastic shim is needed.
5. Using the three #10

1-1/4” self-tapping screws, temporarily screw the bracket to
the hull. DO NOT tighten the screws completely at this time. Follow steps 1-4 in
"How to attach the sensor to the bracket", before proceeding with
"Adjustments".
Adjustments
1. Using a straight edge, sight the underside of the sensor relative to the underside
of the hull. The stern of the sensor should be 1-3 mm (1/16-1/8”) below the bow
of the sensor or parallel to the bottom of the hull.
Note: Do not position the bow of the sensor lower than the stern because aeration
will occur.
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 temporar-
ily fastened to the transom, re-
move it. Apply a marine sealant to
the threads of the three
#10

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.
