1. MOUNTING

1.1 Bottom Discrimination Sounder

The Bottom Discrimination Sounder can be installed on a desktop, deck or on a bulkhead. When selecting a mounting location for the Bottom Discrimination Sounder, keep the following in mind:

Locate the unit away from areas where rain and splash can occur.

The temperature and humidity should be moderate and stable.

Locate the unit away from exhaust pipes and vents.

Locate the unit where shock and vibration are minimal.

The mounting location should be well ventilated.

Keep the unit away from electromagnetic field-generating equipment such as motors and gen- erators.

Leave slack in cables for maintenance and servicing ease.

A magnetic compass will be affected if the unit is placed too close to it. Observe the compass safe distances noted in the safety instructions to prevent disturbance to the magnetic compass.

Fasten the Bottom Discrimination Sounder to the mounting location with four self-tapping screws (420, supplied). Fasten as specified by the drawing at the end of this book. If fastening to an upright wall or bulkhead, mount the unit vertically, not sideways.

CAUTION Do not apply paint, rust protection, etc, to coated surface parts of the unit. These may damage the coated surface areas.

Be especially careful not to apply chemicals to the coated connectors.

1.2 Transducer 520-5PSD, 520-5MSD

1.2.1 Mounting location

The performance of this sounder is directly related to the mounting location of the transducer, es- pecially for high-speed cruising. The installation should be planned in advance, keeping the stan- dard cable length and the following factors in mind:

When the boat has a keel, the transducer should be at least 15-30 cm (5.9 - 11.8) away from it. Typical thru-hull mountings are shown in the figure on the next page.

Air bubbles and turbulence caused by movement of the boat seriously degrade the sounding capability of the transducer. The transducer should, therefore, be located in a position where water flow is the smoothest. Noise from the propellers also adversely affects performance and the transducer should not be mounted nearby. The lifting strakes are notorious for creating acoustic noise, and these must be avoided by keeping the transducer inboard of them.

The transducer must always remain submerged, even when the boat is rolling, pitching or up on a plane at high speed.

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 al- ways in water regardless of the planing attitude

1.2.3 Installation Procedure

1. With the boat hauled out of the water, mark the location selected for mounting the transducer on the bottom of the hull. If the hull is not level within 15 degrees in any direction, fairing blocks made out of teak should be used between the transducer and hull, both inside and outside, to keep the transducer face parallel with the water line. Fabricate the fairing block as shown be- low and make the entire surface as smooth as possible to provide an undisturbed flow of water around the transducer. The fairing block should be smaller than the transducer itself to provide a channel to divert turbulent water around the sides of the transducer rather than over its face.

2. Drill a hole just large enough to pass the threaded stuffing tube of the transducer through the hull, making sure it is drilled vertically.

3. Apply a sufficient amount of high quality caulking compound to the top surface of the trans- ducer, around the threads of the stuffing tube and inside the mounting hole (and fairing blocks if used) to ensure watertight mounting.

4. Mount the transducer and fairing blocks and tighten the locking nuts. Be sure that the trans- ducer is properly oriented and its working face is parallel to the water line.

Note: Do not over-stress the stuffing tube and locking nuts through excessive tightening, since the wood block will swell when the boat is placed in the water. It is suggested that the nut be tight- ened lightly at installation and retightened several days after the boat has been launched.

1.3 Transducer 525-5PWD (transom mount) This type of mounting is very commonly employed for outboard motor boats. Do not use this meth- od on an inboard motor boat because turbulence is created by the propeller ahead of the trans- ducer.

There are two methods of installation: flush with hull (for flat hulls) and projecting from hull (for deep V-hulls).

1.3.1 Installation for flat hulls

A suitable mounting location is at least 50 cm (20.0) away from the engine and where the water flow is smooth.

1. Drill four pilot holes in the mounting location.

2. Attach the transducer to the bracket with self-tapping screws (supplied).

3. Adjust the transducer position so the transducer faces right to the seabed. Note: If necessary, to improve water flow and minimize air bubbles staying on the transducer face, incline the transducer about 5 degrees at the rear. This may require a certain amount of experimentation for fine tuning at high cruising speeds.

4. Fill the gap between the wedge front of the transducer and transom with epoxy material to eliminate any air spaces, and affix tape as shown.

1.3.2 Installation for deep-V hulls

This method is employed on deep-V hulls and provides good performance because the effects of air bubbles are minimal. Install the transducer parallel with water surface; not flush with hull. If the boat is placed on a trailer care must be taken not to damage the transducer when the boat is hauled out of the water and put on the trailer.

1.3.3 Transducer preparation

Before putting the boat in water, wipe the face of the transducer thoroughly with a detergent liquid soap. This will lessen the time necessary for the transducer to have good contact with the water. Otherwise the time required for complete "saturation" will be longer, and the performance will be reduced.

Note: Do not paint the transducer surface. Performance will be affected.

1.4 Optional Water Temperature Sensor ST-02MSB, ST-02PSB

Select a suitable mounting location considering the following points:

Select a mid-boat flat position. The sensor does not have to be installed perfectly perpendicular. The sensor must not be damaged in dry-docking operation.

Select a place apart from equipment generating heat.

Select a place in the forward direction viewing from the drain hole, to allow for circulation of cool- ing water.

Select a place free from vibration.

Procedure

1. Dry-dock the boat.

2. Make a hole of approx. 51 mm (2.0) in diameter in the mounting location.

3. Unfasten locknut and remove the sensor section.

4. Apply high-grade silicone sealant to the flange of the sensor.

5. Pass the sensor casing through the hole.

6. Face the notch on the sensor casing and tighten the locknut.

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.

1. MOUNTING

Mounting location

To ensure the best performance, the sensor must be submerged in aeration-free and turbulence- free water. Mount the sensor close to the centerline of the boat. On slower heavier displacement hulls, positioning it farther from the centerline is acceptable.

Allow adequate space above the bracket for it to release and rotate the sensor upward.

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 coun- tersink 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". Other angles: A 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 transom 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.

3. If the bracket has been temporarily fastened to the transom, remove it. Apply a marine sealant to the threads of the three #10 x 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.

5. Using the vertical adjustment space on the bracket slots, slide the sensor up or down to pro- vide a projection of 3 mm (1/8). Tighten the screws.

Cable routing

Route the sensor cable over the transom, through a drain hole, or through a new hole drilled in the transom above the waterline.

Never cut the cable or remote the connector; this will void the warranty. Always wear safety gog- gles and a dust mask.

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. Posi- tion a cable clamp 50 mm (2.0") above the bracket and mark the mounting hole with a pencil.

4. Position the second cable clamp halfway between the first clamp and the cable hole. Mark this mounting hole.

5. If a hole has been drilled in the transom, open the appropriate slot in the transom cable cover. Position the cover over the cable where it enters the hull. Mark the two mounting holes.

6. At each of the marked locations, use a 3 mm or 1/8" bit to drill a hole 10 mm (0.4") deep. To prevent drilling too deeply, wrap masking tape around the bit 10 mm (0.4") from the point.

7. Apply marine sealant to the threads of the #6 x 1/2" self-tapping screw to prevent water from seeping into the transom. If you have drilled a hole through the transom, apply marine sealant to the space around the cable where it passes through the transom.

8. Position the two cable clamps and fasten them in place. If used, push the cable cover over the cable and screw it in place.

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. Coil any excess cable and secure it in place with zip-ties to prevent damage.
