Stainless steel housing in a metal hull - To prevent
electrolytic corrosion, the stainless steel housing must be
isolated from the metal hull. Slide the isolation bushing
onto the housing (see Figure 5). Apply additional marine
sealant to the surfaces of the bushing that will contact the
hull, filling any cavities in and around the isolation bushing.
Installing
1. From outside the hull, thread the cable through the
mounting hole. Push the housing into the mounting hole
using a twisting motion to squeeze out excess sealant.
12° and 20° models - From inside the hull, point the arrow
on the top of the transducer (and the cable exit) toward the
KEEL or centerline of the boat (see Figure 1). This will
align the angle of the element inside the transducer with
the deadrise angle of your hull.
2. Slide the washer onto the housing (see Figure 4 or 5).
B150M, B619, SS150M, SS619 - Also slide the spacer
onto the housing and rest it against the washer. 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.
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.
3. Screw the hull nut in place.
Plastic housing - Do not clamp tightly on the wrench flats
to avoid possibly fracturing the housing.

Plastic hull nut - Hand-tighten only. Do not over tighten.
Metal hull nut - Tighten with slip-joint pliers.
Metal hull - Use the spacer if there are not enough threads
to tighten the hull nut against the hull.
Cored Fiberglass Hull - Do not over tighten, crushing the
hull.
Wood hull - Allow the wood to swell before tightening the
hull nut.
4. Remove any excess marine sealant on the outside of the
hull to ensure smooth water flow under the transducer.
Cable Routing & Connecting
CAUTION: If your 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
waterproof connector or cutting the cable, except when using
a water-tight junction box, will void the sensor warranty.
1. Route the cable to the instrument, 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
chaffing. To reduce electrical interference, separate the
transducer cable from other electrical wiring and the
engine. Coil any excess cable and secure it in place using
cable ties to prevent damage.
2. Refer to the echosounder owner's manual to connect the
transducer to the instrument.
