4. INSTALLATION Mounting on the bulkhead, Flush mounting in a panel 4.1 Display Unit Mounting considerations See the instructions on the bulkhead or flush mounting template (supplied). The display unit can be installed on a desktop, on the bulkhead or flush mounted in a panel. When choosing a location keep the following in mind: 4.2 Thru-hull Mount Transducer • Keep the display unit out of direct sunlight. • The temperature and humidity should be moderate and stable.
submerged, even when the boat is rolling, pitching or up on a plane at high speed. Typical thru-hull mount transducer installations • A practical choice would be somewhere between 1/3 and 1/2 of the boat’s length from the stern. For planing hulls, a practical location is generally rather far astern, so that the transducer is always in water regardless of the planing attitude.
Hole for stuffing tube DO NOT paint the transducer. Performance will be affected. BOW Upper Half 4.3 Transom Mount Transducer The transom mount transducer is very commonly employed, usually on relatively small I/O or outboard boats. Do not use this method on an inboard motor boat because turbulence is created by the propeller ahead of the transducer. Lower Half Saw along slope of hull. Construction of fairing block 3.
Note: If necessary, to improve water flow and minimize air bubbles staying on the transducer face, incline the transducer about 5° at the rear. This may require a certain amount of experimentation for fine tuning at high cruising speeds. 5 x 20 5 x 20 4. Fill the gap between the wedge front of the transducer and transom with epoxy material to eliminate any air spaces. M5 x 14 No. 2 5 x 20 5 x 20 Transom mount transducer, mounted projecting from hull No.
• Avoid a location where the rising angle of the hull exceeds 15°, to minimize the effect of the boat’s rolling.

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”. Other angles: The shim is required. Skip to step 2 of “Adjusting”.
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.
1. If a hole must be drilled, choose a location well above the waterline. Check for obstructions such as trim tabs, pumps, or wiring inside the hull. Mark the location with a pencil. Drill a hole through the transom using a 19 mm or 3/4” bit (to accommodate the connector). 2. Route the cable over or through the transom. 3. On the outside of the hull secure the cable against the transom using the cable clamps. Position a cable clamp 50 mm(2”) above the bracket and mark the mounting hole with a pencil. 4.
6. Face the notch on the sensor toward boat’s bow and tighten the flange. 7. Set the sensor section to the sensor casing and tighten the locknut. 8. Launch the boat and check for water leakage around the sensor. 9. Route the cable to the instrument being careful not to tear the cable jacket when passing it though the bulkhead(s) and other parts of the boat. To reduce electrical interference, separate the sensor cable from other electrical wiring and “noise” sources.
Establishing the ground Connect to XDR port at rear of display unit The ground wire (1.25 sq or more, local supply) should be as short as possible. MJ-A10SPF The signal line ground is isolated from the chassis ground, however the power line is not insulated. Therefore, when connecting eternal equipment having positive ground, do not ground the signal line to the chassis. If excessive noise shows on the screen, the ground may be inadequate.
