APPENDIX 2 INSTALLATION FOR
TRANSDUCER (THRU-HULL MOUNT)
This appendix provides a copy of the installation instructions for AIRMAR transducer.
525T-LTD/12 and 525T-LTD/20 corresponds to B60, SS60-SLTD/12 and SS60-SLTD/20 to SS60.
Thru-Hull
Tilted Element
Models: B60, B75H/M/L, B150M, B619
P19, SS60, SS150M, SS565, SS619
U.S. Patent No. 7,369,458. UK Patent No. 2 414 077. U.S. Patent Pending
Follow the precautions below for optimal product
performance and to reduce the risk of property
damage, personal injury, and/or death.
WARNING: Always wear safety goggles and a dust
mask when installing.
WARNING: Immediately check for leaks when the boat
is placed in the water. Do not leave the boat unchecked
for more than three hours. Even a small leak may allow
considerable water to accumulate.
WARNING: B150M, B619, SS150M, SS619 - Do not
use the spacer if there is insufficient space to tighten the
nut, or it is within 11 mm (1/2") of the top of the housing.
WARNING: Stainless steel housing in a metal hull -
Be sure the washer contacts the hull. Do not tighten the
hull nut with the washer against the isolation bushing,
as the housing will not be firmly installed. If necessary,
sand the isolation bushing until the washer rests against
the hull.
CAUTION: CHIRP transducer - Do not install in the
engine compartment or other hot place. The transducer
may fail if it overheats.
CAUTION: CHIRP transducer - Always operate the
transducer in water. Operating in air will allow the
transducer to overheat resulting in failure.
CAUTION: The arrow on the top of the transducer must
point toward the keel or centerline of the boat. This will
align the angle of the element inside the transducer with
the deadrise angle of your hull.
CAUTION: Never pull, carry, or hold the transducer by
its cable; this may sever internal connections.
CAUTION: Plastic housing - Never use a fairing with
a plastic housing; the protruding sensor would be
vulnerable to damage from impact.
CAUTION: Metal housing - Never install a metal
housing on a vessel with a positive ground system.
CAUTION: Stainless steel housing in a metal hull -
The stainless steel housing must be isolated from a
metal hull to prevent electrolytic corrosion. Use the
isolation bushing supplied.
CAUTION: Never use solvents. Cleaners, fuel, sealant,
paint and other products may contain solvents that can
damage plastic parts, especially the transducer's face.
IMPORTANT: Read the instructions completely before
proceeding with the installation. These instructions
supersede any other instructions in your instrument
manual if they differ.

Applications
• Plastic housing recommended for fiberglass or metal
hulls only. Never install a plastic housing in a wood hull
since swelling of the wood can fracture the plastic.
• Bronze housing recommended for fiberglass or wood
hulls. Never install a bronze housing in a metal hull,
because electrolytic corrosion will occur.
• Stainless steel housing compatible with all hull
materials. Recommended for metal hulls to prevent
electrolytic corrosion provided the stainless steel
housing is isolated from the metal hull.
Match Tilt Angle of Transducer to Deadrise
Be sure the tilt angle of your transducer model matches
the deadrise angle of your boat at the mounting location.
The tilt angle is printed on the top of the transducer (see
Figure 1). To measure the deadrise angle of your hull at
the selected mounting location, use an angle finder or a
digital level (see Figure 2).
• 0˚ models - For hull deadrise angles from 0˚ to 7˚
• 12˚ models - For hull deadrise angles from 8˚ to 15˚
B75H-12˚ - For hull deadrise angles from 6˚ to 15˚
B75M-12˚ - For hull deadrise angles from 6˚ to 15˚
B75L-12˚ - For hull deadrise angles from 0˚ to 24˚
• 20˚ models - For hull deadrise angles from 16˚ to 24˚
