Height without
speed sensor
191 mm (7.5")
Note 1: Do not mount the sensor in an area of turbulence or bubbles: near water intake or dis-
charge openings; behind strakes, struts, fittings, or hull irregularities; behind eroding paint (an in-
dication of turbulence).
Note 2: Avoid mounting the sensor where the boat may be supported during trailering, launching,
hauling, and storage.
Note 3: For single drive boat, mount on the starboard side at least 75 mm (3.0") beyond the
swing radius of the propeller.
Note 4: For twin drive boat, mount between the drives.
Installation of Bracket
1. Cut out the installation template (enclosed with transducer) along the dotted line.
2. At the selected location, position the template, so the arrow at the bottom is aligned with the
bottom edge of the transom. Being sure the template is parallel to the waterline, tape it in
place.
Warning: Always wear safety goggles and a dust mask.
3. Using a 4 mm, #23, or 9/64" bit, drill three holes 22 mm (0.9"") deep at the locations indicated.
To prevent drilling too deeply, wrap masking tape around the bit 22 mm (0.9") from the point.
Fiberglass hull: Minimize surface cracking by chamfering the gelcoat. If a chamfer bit or
countersink bit is not available, start drilling with a 6mm or 1/4" bit to a depth of 1 mm (0.04")
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 "Adjusting".
