1. MOUNTING
Other angles: The shim is required. Skip to step 2 in "Adjusting".
If you do not know the transom angle, temporarily attach the bracket and sensor to the tran-
som to determine if the plastic shim is needed.
5. Using the three #10 x 1-1/4" self-tapping screws, temporarily screw the bracket to the hull. DO
NOT tighten the screws completely at this time. Follow the step 1-4 in "Attaching the sensor
to the bracket", before proceeding with "Adjusting".
Attaching the sensor to the bracket
1. If the retaining cover near the top of the bracket is closed, open it by depressing the latch and
rotating the cover downward.
2. Insert the sensor's pivot arms into the slots near the top of the bracket.
3. Maintain pressure until the pivot arms click into place.
4. Rotate the sensor downward until the bottom snaps into the bracket.
5. Close the retaining cover to prevent the accidental release of the sensor when the boat is un-
derway.
Adjusting
1. Using a straight edge, align 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.
