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 (see Figure 7). 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 mounting location. Check that the
O-ring gasket is in the groove around the lip of the transducer.
4. Grasp the transducer by the handle and lower it into the tank
(see Figure 8). There is no fore or aft to the transducer; it fits
either way.
M265LH/LM—Be careful lowering the transducer. The metal
plate on each side make a snug fit against the tank opening.
5. Attach the transducer to the tank. Use the four socket-head cap
screws, four lock washers, and four flat washers supplied.
Lightly tighten with the Allen wrench supplied, using a force not
exceeding 35 in.-lb. Do not over tighten. (Use a blade
screwdriver to remove the Allen wrench from the recess in the
handle of the transducer. Replace the Allen wrench after use.)
6. Top-off the propylene glycol in the tank. However, allow a small
air space to accommodate expansion with temperature
changes. Using the funnel supplied, pour the fill-liquid through
one of the fill/vent holes until the tank is full (see Figure 9). The
second hole will act as a vent. (Alternately, the tank can be filled
using standard diameter tubing secured with a band clamp.)
Attach the stoppers supplied and plug both fill/vent holes. To
ease sliding, lubricate the stoppers with the fill liquid. Tie the
funnel to the handle to keep it near-at-hand.
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 provided. Removing the water-proof
connector or cutting the cable, except when using 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.
Replacement Transducer & Parts
The information needed to order a replacement Airmar transducer
is printed on the cable tag. Do not remove this tag. When ordering,
specify the part number, date, and frequency in kHz. For con-
venient reference, record this information at the top of page one.
Lost, broken, or worn parts should be replaced immediately.
