Operating Instructions and Installation Instructions

then the chosen location must be in the water at all times. If the

transducer is not placed in a smooth flow of water, interference

caused by bubbles and turbulence will show on the sonar's display in

the form of random lines or dots whenever the boat is moving.

NOTE:

Some aluminum boats with strakes or ribs on the outside of the

hull create large amounts of turbulence at high speed. These boats

typically have large outboard motors capable of propelling the boat

at speeds faster than 35 mph. Typically, a good location on alumi-

num boats is between the ribs closest to the engine.

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

interfere 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 prevent 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.

Good and poor transducer locations.

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.
