1.Installation of Standard Equipment

1.1Installation of Display Unit

Mounting considerations

The display unit can be installed on a tabletop, on the overhead or flush mounted in a console or panel.

Figure 1-1 Tabletop, overhead mounting methods

When selecting a mounting location for the display unit keep the fol- lowing in mind:

???Keep the display unit out of direct sunlight.

???The temperature and humidity should be moderate and stable.

???Locate the unit away from exhaust pipes and vents.

???The mounting location should be well ventilated.

???Mount the unit where shock and vibration are minimal.

???Keep the unit away electromagnetic field generating equipment such as motor, generator.

???For maintenance and checking purposes, leave sufficient space at the sides and rear of the unit and leave slack in cables.

???A magnetic compass will be affected if placed too close to the display unit. Observe the following compass safe distances to pre-

vent disturbance to the magnetic compass:

Standard compass: 0.82 meters

Steering compass: 0.62 meters

Mounting procedure

Follow the procedure below to mount the display unit on a tabletop or the overhead.

Tabletop, overhead mounting

1.Fix the hanger by four pan head screws M5 X 16.

2.Screw knob bolts in display unit, set it to hanger, and tighten knob bolts.

3.Attach hard cover to protect LCD.

Figure 1-2 Tabletop, overhead mounting of display unit

Flush mounting

Note: Use supplied pan head screws when the thickness of the bulk- head is from 11 to 14 mm. For bulkhead which exceeds 14 mm in thickness the length of the pan head screws should be bulkhead thick- ness+7.8?? 1.5 mm. Also the length of B should max. 8mm.

1.Prepare a cutout in the mounting location whose dimensions are as shown in Figure 1-3.

2.Fix the display unit by six pan head screws M4 X 20. Refer to the outline drawing on page D-2.

1.2 Installation of Antenna Unit (GP-1650DF only)

Mounting considerations

Install the antenna unit referring to the installation diagram on page D-3 or D-4. When selecting a mounting location for the antenna unit, keep in mind the following points:

???Select a location out of the radar beam. The radar beam will ob- struct or prevent reception of the GPS satellite signal.

???The location should be well away from a VHF antenna. A GPS receiver is interfered by a harmonic wave of a VHF antenna.

???There should be no interfering object within the line-of-sight to the satellites. Objects within line-of-sight to a satellite, for example, a mast, may block reception or prolong acquisition time.

???Mount the antenna unit as high as possible. Mounting the antenna

unit as high as possible keeps it free of interfering objects and water spray, which can interrupt reception of GPS satellite signal if the water freezes.

??? The length of the whip antenna for the GP-1650DF should be no longer than 1.2 meter to prevent antenna damage. Do not use a 2.5 meter whip antenna.

???Do not shorten the antenna cable.

???If the antenna cable is to be passed through a hole which is not large enough to pass the connector, you may unfasten the connec- tor with a needle nose pliers and 3/8-inch open-end wrench. Re-

fasten it as shown in Figure 1-4 after running the cable through the hole.

1.3 Installation of Transducers

Installing the inside-hull mount transducer

Necessary tools

You will need the following tools:

???Sandpaper (#100)

???Silicone sealant

???Silicone grease

Remarks on installation

???Do the installation with the boat hauled out of the water.

???Turn off the engine while installing the equipment.

???Install the transducer in the engine room.

Selecting the mounting location

Keep the following points in mind when selecting a mounting loca- tion:

???The mounting location should be where the hull is of single-hull thickness and is void of air or flotation materials other than solid fiberglass between the transducer face and the water.

???Do not place the transducer over hull struts or ribes which run under the hull.

???Avoid a location where the rising angle of the hull exceeds 15??, to minimize the effect of the boat???s rolling.

???You will finalize the mounting location through some trial and error. The procedure for this is shown later.

Figure 1-5 Inside-hull transducer mounting location

Installing the thru-hull mount transducer

Transducer mounting location

This type of mounting provides the best performance of all, since the transducer protrudes from the hull and the effect of air bubbles and turbulence neat the hull skin is reduced. When the boat has a keel, the transducer should be at least 30 cm away from it. Typical through hull mountings are shown in the figure on the next page.

The performance of the video sounder is directly related to the mount- ing location of the transducer, especially for high-speed cruising. The installation should be planned in advance, keeping the standard cable length (8 m) and the following factors in mind:

??? Air bubbles and turbulence caused by movement of the boat seri- ously degrade the sounding capability of the transducer. The trans- ducer 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 loca- tion is generally rather far astern, so that the transducer is always in water regardless of the planing attitude.

Procedure for installing the thru-hull mount transducer

1.With the boat hauled out of the water, mark the location selected for mounting the transducer on the bottom of the hull.

2.If the hull is not level within 15?? 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 below and make the entire surface as smooth as possible to provide an un- disturbed 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.

Hole for stuffing tube

Saw along slope of hull.

Figure 1-15 Construction of fairing block

3.Drill a hole just large enough to pass the threaded stuffing tube of the transducer through the hull, making sure it is drilled verti- cally.

4.Apply a sufficient amount of high quality caulking compound to the top surface of the transducer, around the threads of the stuff- ing tube and inside the mounting hole (and fairing blocks if used) to ensure watertight mounting.

5.Mount the transducer and fairing blocks and tighten the locking nuts. Be sure that the transducer is properly oriented and its work- ing face is parallel to the waterline.

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 tightened lightly at installation and retightened several days after the boat has been launched.

Installing the transom mount transducer

This type of mounting is very commonly employed, usually on rela- tively 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.

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

D>50 cm

Figure 1-16 Transom mount transducer mounting locations

Installing the transom mount transducer flush with hull

(for flat hulls)

A suitable mounting location is at least 50 cm 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 tapping screws (sup- plied).

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?? at the rear. This may require a certain amount of experi- mentation for fine tuning at high cruising speeds.

4.Fill the gap between the wedge front of the transducer and tran- som with epoxy material to eliminate any air spaces.

Figure 1-17 Transom mount transducer, mounting flush with hull

Installing the transom mount transducer projecting from hull

(for deep-V hulls)

This method is employed on deep-V hulls and provides good perfor- mance because the effects of air bubbles are minimal. Install the trans- ducer 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.

Figure 1-18 Transom mount transducer, projecting from hull

Transducer preparation

Before putting the boat in water, wipe the face of the transducer thor- oughly with a detergent liquid soap. This will lessen the time neces- sary for the transducer to have good contact with the water. Otherwise the time required for complete "saturation" will be lengthened and performance will be reduced.

Do not paint the transducer. Performance will be affected.

Triducer 524ST-MSD, 525ST-MSD

The triducer is designed for thru-hull mounting.

Mounting considerations

When selecting a mounting location keep the following points in mind:

???Air bubbles and turbulence caused by movement of the boat seri- ously degrade the sounding capability of the transducer. The trans- ducer 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 loca- tion is generally rather far astern, so that the transducer is always in water regardless of the planing attitude.

Ground

The display unit

contains several CPUs. While they

are operating, they radiate noise, which

can interfere with radio equipment.

Ground the unit to

prevent interference. The grounding wire should be 1.25 sq or larger and as short as possible. Connect the grounding wire to ship's ground. On a fiberglass boat, it is best to install a ground plate that measures about 20 cm by 30 cm on the outside of the hull bottom to provide a ground point. If this is not practical, the engine block can be used. Also, the antenna unit GPA-018S(option) is required to ground with IV-1.25 sq cable as short as possible.

Note: Use a ???closed??? lug to make the ground connection at the dis- play unit. Do not use an ???open-type??? lug ( ).
