2. The transducer should be installed with its face pointing straight
down, if possible.
3. If the transducer is mounted on the transom, make sure it doesn't inter-
fere with the trailer or hauling of the boat. Also, don't mount it closer
than approximately one foot from the engine's lower unit. This will pre-
vent cavitation (bubble) interference with propeller operation.
4. If possible, route the transducer cable away from other wiring on the
boat. Electrical noise from engine wiring, bilge pumps and aerators
can be displayed on the sonar's screen. Use caution when routing the
transducer cable around these wires.
CAUTION: Clamp the trans-
ducer cable to transom near
the transducer. This will help
prevent the transducer from
entering the boat if it is
knocked off at high speed.

How low should you go?
For most situations, you should install your Skimmer transducer so
that its centerline is level with the bottom of the boat hull. This will
usually give you the best combination of smooth water flow and protec-
tion from bangs and bumps.
