CAUTION: The fiberglass hull below the transducer must be SOLID. The transducer will not transmit through coring material such as foam or balsa wood.

CAUTION: Do not install in the engine compartment or other hot place. The transducer may fail if the temperature of the liquid in the tank exceeds 60° C (140° F).

CAUTION: Always operate the transducer in liquid. Operating in air will allow the transducer to overheat resulting in failure.

CAUTION: Never pull, carry, or hold the transducer by the cable. This may sever internal connections.

CAUTION: Never use solvents. Cleaner, fuel, sealant, paint, and other products may contain solvents that can damage plastic parts, especially the transducer’s face.

IMPORTANT: Please read the instructions completely before proceeding with the installation. These instructions supersede any other instructions in your instrument manual if they differ.

Record the information found on the cable tag for future reference.

Boat Types (Figure 3)

• Displacement hull powerboats—Locate amidships near the centerline. The side of the hull where the propeller blades are moving downward is preferred.

• Planing hull powerboats—Mount well aft, on or near the centerline, and well inboard of the first set of lifting strakes to ensure that the transducer will be in contact with the water at high speeds. The side of the hull where the propeller blades are moving downward is preferred.

Outboard and I/O—Mount just forward of the engine(s). Inboard—Mount well ahead of the propeller(s) and shaft(s). Stepped hull—Mount just ahead of the first step.

Mounting Location

About Fiberglass Hulls

Since the hull absorbs acoustic energy, transmitting through the hull reduces the transducer’s performance. Fiberglass hulls are often cored in places for added strength or to reduce weight. These cored areas contain balsa wood or structural foam which are poor sound conductors. Do not locate the transducer over coring.

Choose a Location

• Where the fiberglass is SOLID (no air bubbles are trapped in the fiberglass resin) and where no coring, flotation material, or dead air space is sandwiched between the inside skin and outer skin of the hull.

• Where the hull below the transducer will be in contact with the water at all times.

• Where the water flowing under the hull is smoothest with a minimum of bubbles and turbulence (especially at high speeds). Do not mount the transducer in line with or near water intake or discharge openings; or behind strakes, fittings, or hull irregularities that will disturb the water flow.

• Where the transducer beam will not be blocked by the keel or propeller shaft(s).

The results of this test are used as a basis of comparison to determine the best in-hull location for the transducer.

1. Take the boat to the maximum depth in which you will be operating the echosounder. If deep water is not available, find a location with at least 30m (100').

2. Connect the transducer to the echosounder.

3. Tie a rope securely around the handles of the transducer (Figure 4). Lower it over the side of the boat until the active face is fully submerged and parallel to the water surface.

4. Observe the echosounder’s performance and the depth reading.

Testing the Location

While the boat is at the same site (depth of water), test the transducer inside the hull at the mounting location. Use one of the test methods below:

A.If the transducer will be located near the stern and the boat

has a minimum deadrise angle—Clean away any build-up of dirt and/or grease using detergent or a weak solvent such as alcohol. Place the transducer against the hull and allow bilge water to cover the surface where they touch (Figure 5-A).

B.For a moderate deadrise angle—If the hull surface is not

smooth, grind it with a disc sander. Place the transducer inside a thin plastic bag. Partially fill the bag with water and close it tightly with a cable tie. Wet the surface of the hull and press the active face of the transducer against it through the bag (Figure 5-B).

• Away from interference caused by power and radiation sources such as: the propeller(s) and shaft(s), other machinery, other echosounders, and other cables. The lower the noise level, the higher the echosounder gain setting that can be used.

• Where the deadrise angle does not exceed either 12° on the long side of the tank or 22° on the short side of the tank.

• Where there is space inside the vessel for the size of the tank and removing the transducer.

• Mount in a cool well-ventilated area away from the engine to avoid overheating the liquid inside the tank.

Figure 5. Testing the transducer at the selected location

C.For any location—If the hull surface is not smooth, grind it with

a disc sander. Coat the active face of the transducer with a

water-based lubricant (such as K-Y

jelly). With a twisting motion, press the face firmly against the hull (Figure 5-C). After testing, wipe away all traces of the lubricant from the transducer’s face.

Observe the echosounder’s performance and compare it to the baseline. Look for a stable depth reading that is similar to the baseline. Compare the thickness and intensity of the bottom trace.

If the performance is close to the baseline, this is a good mounting location. Remember, some energy is lost transmitting through the hull. If the test reading differs markedly from the baseline, you will need to find another location to install the transducer.

NOTE: If there is no reading or it is erratic, the transducer may be positioned over coring which is absorbing the acoustic energy. Choose another location. If no other location is available, check with the boat manufacturer to be certain coring is present.

Installation

Marking & Cutting

CAUTION: For optimal performance, the transducer must be installed so the beam will be aimed straight down. This is accomplished by cutting the tank to match the deadrise angle of the hull.

1. When you are satisfied that the selected mounting location is

optimal, place the tank up-side-down on the hull (Figure 6).

NOTE: The tank can be placed with either a short side or long side parallel to the centerline of the boat.

2. Holding a carpenter’s level even with the lower corner of one of the sides to be cut, draw a level line on the tank. Repeat this process on the opposite side of the tank. Connect these two lines to form the SHORTEST side of the tank. Be sure the lines are level, as they will be the cutting guidelines.

3. Before cutting the tank, be sure the TALLEST side will be

closest to the centerline (keel) of the boat after the tank is installed. And be sure to observe the “Do not cut above this

line” mark.

Using a saw, cut the three sides of the tank along the guidelines drawn. It may be necessary to further shape the tank to the hull to ensure a liquid-tight bond.

4. The tank is provided with a cork liner to reduce sound echoes. After the tank has been cut, wrap the cork liner around the inside of the tank (Figure 7). Butt the sides of the liner along the center of the tallest side. Trace the bottom edge of the tank onto the liner.

NOTE: There may be a gap between the butted edges which will not affect performance.

CAUTION: Do not mark or cut the tank in the space labeled “Do not cut above this line.”

Draw a level line starting at the lower corner.

Do not mark below this line.

Bonding the Tank

CAUTION: The tank must be liquid-tight. To ensure a tight bond, the hull surface under and around the tank must be smooth, free of paint or any other finish, clean, and dry.

1. To ensure a tight bond, remove any paint or other hull finish. If the surface is rough, use a disk sander to smooth an area slightly larger than the tank. Clean any dust, grease, or oil from the hull surface with a weak solvent, such as alcohol. Dry the effected area.

2. Use 80 grit sand paper to sand the outside and inside of the tank up 50mm (2") above the bottom edge. Remove the dust with a weak solvent, such as alcohol. Dry the effected area.

3. Use an approved bonding material (see Tools & Materials on page 1). Glass the tank to the hull with fiberglass resin, using standard fiberglass technique. Alternatively, apply a generous bead of marine putty/ sealant to the bottom edge of the tank following the manufacturer’s instructions (Figure 8). Press the tank firmly in place. Apply a second bead around the inside of the tank. And apply a third bead around the outside of the tank.

4. Allow the bonding material to cure. The seal must be liquid-tight.

Installing the Transducer

CAUTION: Do not use sealant or adhesive on the gasket. To do so may break the tank when the transducer is removed.

CAUTION: Do not over tighten the bolts to avoid cracking the tank.

1. After the bonding material has cured, insert the cork liner into the tank (Figure 8). Butt the edges along the center of the tallest side. Note, there may be a gap, but this will not affect performance.

2. Following the manufacturer’s directions for use, pour propylene glycol into the tank until it covers the exposed hull.

3. Before installing the transducer, wipe it clean of any lubricant that was used in testing the location.

4. Grasp the transducer by the handles and lower it into the tank. There is no fore or aft to the transducer; it fits either way.

5. Attach the transducer to the tank. Use the six remaining 9/16" hex-head bolts and six lock washers supplied. Tighten using a torque wrench with a force not exceeding 85 in-lb. Do not over tighten.

6. Top-off the propylene glycol in the tank. However, allow a small air space to accommodate expansion with temperature changes. Using a funnel, pour the fill-liquid through one of the fill/vent holes until the tank is full. The second hole will act as a vent. Plug both holes with the vent plugs supplied.

Cable Routing & Connecting

CAUTION: If the transducer came with a connector, do not remove it to ease cable routing. If the cable must be cut and spliced, use Airmar’s splash-proof Junction Box No. 33-035 and follow the instructions supplied. Removing the water-proof connector or cutting the cable, except when using a water-tight junction box, will void the transducer warranty.

1. Route the cable to the echosounder being careful not to tear the cable jacket when passing it through the bulkhead(s) and other parts of the boat. Use grommets to prevent chafing. To reduce electrical interference, separate the transducer cable from other electrical wiring and the engine(s). Coil any excess cable and secure it in place with cable ties to prevent damage.

2. Refer to your echosounder owner’s manual to connect the transducer to the instrument.

Operation

Monitor the transducer ID line for the internal temperature of the fill liquid within the tank. The transducer may fail if the fill-liquid reaches temperatures above 60° C (140° F).
