1. INSTALLATION
1.1 Display Unit Installation
The Display Unit (GP-1871F or GP-1971F) can be mounted in one of two ways: desktop (bracket) or flush mount (in the console, etc.).
When selecting a mounting location, keep the following points in mind:
• Determine the suitability of the mounting location before permanently mounting the
unit. Bulkheads and roofs can affect the incoming/outgoing signals, depending on
the shape of the vessel, preventing communication with the radar sensor. Signals
are strongest to the fore/aft direction of the unit; weakest to either side of the unit.
The unit should be located within the following distances from the radar sensor, to
ensure a stable connection.
Vessels with no obstructions: approximately 5 m, or less.
Vessels with obstructions: approximately 2 m, or less. (Avoid locations where the
obstruction(s) are composed of metal, carbon-fiber, or similar materials.)
• There should be no interfering objects within the line-of-sight to the satellites. An object within line-of-sight to satellites, for example, a mast, may block reception or prolong acquisition time. Select a location out of the radar and inmarsat beams. Those
beams will obstruct or prevent reception of the GPS satellite signal.
• Locate the unit away from areas subject to water splash and rain.
• The operating temperature range of this unit is -15°C to +55°C. Be sure the mounting location satisfies this requirement.
• 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 from electromagnetic field-generating equipment such as motors and generators.
• Select a location away from VHF/UHF antennae, to avoid interference caused by
harmonic waves.
• Referring to the outline drawings at the back of this manual, leave sufficient room
for service and maintenance.

the sensor must be connected to the switchboard or a similar power-governance device. For DRS4W installation instructions, see the manual included with the DRS4W.
1.3 Transducer Installation
CAUTION
Do not transmit with the transducer out of water.
The unit and transducer may be damaged.
1.3.1 How to mount a transducer through the hull
Transducer mounting location
The thru-hull mount transducer provides the best performance of all, since the transducer protrudes from the hull and the effect of air bubbles and turbulence near the hull
skin is reduced. If your boat has a keel, the transducer should be at least 30 cm away
from it.
The performance of this fish finder is directly related to the mounting location of the
transducer, especially for high-speed cruising. The installation should be planned in
advance, keeping the length of the transducer cable and the following factors in mind:
• 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 your 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.

1. INSTALLATION
Installation procedure
1. With the boat hauled out of the water, mark the location chosen 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 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.
3. Drill a hole just large enough to pass the threaded stuffing tube of the transducer
through the hull, making sure it is drilled vertically.
4. Apply a sufficient amount of high quality caulking compound to the top surface of
the transducer, around the threads of the stuffing 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 locknut. Be sure that the
transducer is properly oriented and its working face is parallel to the waterline.

Note: Do not over-stress the stuffing tube and locknut 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 re-tightened several days after the
boat has been launched.
Transducer preparation
Before putting your 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 lengthened and performance will be reduced.
DO NOT paint the transducer. Performance will be affected.

1.3.2 Transom mount transducer
The optional 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.
DO NOT over-tighten screws, to prevent damage to the transducer.
Installation procedure
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 for self-tapping screw (I5u20) in the mounting location.
2. Coat the threads of the screws (M5x14) for the transducer with marine sealant for
waterproofing. Attach the transducer to the mounting location with the self-tapping
screws.
3. Adjust the transducer position so the transducer faces right to the bottom. 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.
4. Tape the location shown in the figure below.

1.3.3 How to mount a transducer inside the hull
The transducer may also be installed inside the hull on FRP boats. However, this installation method affects the ability to detect the bottom, fish and other objects because the ultrasound pulse is weakened when it passes through the hull.
Note: This mounting method should not be used to mount a transducer that supports
the RezBoost
performance is greatly degraded.
Necessary tools
The following tools are required:
• Sandpaper (#100)
• Marine sealant
• Water-filled plastic bag
Remarks on installation
• Do the installation with the ship moored at a dock, etc. The water depth should be 6.5
to 32 feet (2 to 10 meters).
• Turn off the engine.
• Do not power the unit with the transducer in the air, to prevent damage to the transducer.
• Do not use this method on a double layer hull.
• Before attaching the transducer to the hull, check that the site is suitable, by following
steps 1 to 3 in the installation procedure below.
Installation procedure
The attenuation of the ultrasound pulse varies with the thickness of the hull. Select a
location where attenuation is the lowest.
1. Select 2-3 locations considering the four points mentioned below.
• Mount the transducer at a location 1/2 to 1/3 of the length of your boat from the stern.
• The mounting location is between 15 to 50 cm from the centerline of the hull.
• Do not place the transducer over hull struts or ribs 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.
2. Decide the most suitable site from the locations selected.
1) Connect the power cable and transducer cable to the display unit.
2) Put the transducer into water-filled plastic bag. Press the transducer against

Check if the bottom echo appears on the screen, in the display area.
If no bottom echo appears, repeat the procedure unit a suitable location is
found.
3. Remove the transducer from the plastic bag and wipe the face of transducer with
a cloth to remove water and any foreign material. Lightly roughen the face with
#100 sandpaper. Also, use the sandpaper to roughen the inside of the hull where
the transducer is to be mounted.
4. Wipe off any sandpaper dust from the face of the transducer.
5. Dry the face of the transducer and the hull. Coat the transducer face and mounting
location with marine sealant. Hardening begins in approx. 15 to 20 minutes so do
this step without delay.
6. Attach the transducer to the hull. Press the transducer firmly down on the hull and
gently twist it back and forth to remove any air which may be trapped in the marine
sealant.
7. Support the transducer with a piece of wood to keep it in place while the sealant
is drying. It takes 24 to 72 hours to harden completely.

1.3.4 Triducer
DO NOT over-tighten screws, to prevent damage to the transducer.
525STID-MSD
The optional triducer 525STID-MSD is designed for thru-hull mounting.
525STID-PWD
The optional triducer 525STID-PWD is deigned for transom mounting.
Pretest for speed and temperature
Connect the sensor to the instrument and spin the paddlewheel. Check for a speed
reading and the approximate air temperature. If there is no reading, return the sensor
to your place of purchase.
Tools and materials required
• Scissors • Masking tape
• Safety goggles • Dust mask
• Electric drill • Screwdrivers
• Drill bit:
For bracket holes: 4 mm, #23, or 9/64”
For fiberglass hull: chamfer bit (preferred), 6 mm, or 1/4”
For transom hole: 9 mm or 3/4” (optional)
For cable clamp holes: 3 mm or 1/8”
• Straight edge • Marine sealant
• Pencil • Cable ties
• Water-based anti-fouling paint (mandatory in salt water)
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 your 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
in-take or discharge openings; behind
strakes, struts, fittings, or hull irregularities; behind eroding paint (an indication 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") beyond the swing radius of the propeller, as shown in the right figure.
Note 4: For twin drive boat, mount between the
drives.
How to install the 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 (7/8”) deep at
the locations indicated. To prevent
drilling too deeply, wrap masking
tape around the bit 22 mm (7/8”)
from the point.
Align template vertically.
Deadrise angle
Align template arrow with
bottom edge of transom.
Slope of hull
Parallel to
waterline
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 (1/16”).
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 "Adjustments".
• Other angles: The shim is required. Skip to step 2 of "Adjustments".
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 #10u1-1/4” 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 "How to attach the sensor to the bracket", before proceeding with
"Adjustments".
Adjustments
1. Using a straight edge, sight 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.
2°-10° transom angle (stepped transom and jet boats): Position the shim with
the tapered end down.

1. INSTALLATION
19°-22° transom angle (small aluminum and fiberglass boats): Position the
shim with the tapered end up.
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 provide a projection of 3 mm (1/
8”). Tighten the screws.
How to attach the sensor to the bracket
Hull projection 3 mm (1/8")
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 your
boat is underway.
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. 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
(3/8”) deep. The prevent drilling too deeply, wrap masking tape around the bit 10
mm (3/8”) from the point.
7. Apply marine sealant to the threads of the #6u1/2” 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 display unit 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.

How to route the cable
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 goggles 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.
