(which do not conduct sonar signals) make inside the hull mounting inadvisable.

Thru-hull mounting may require the use of a fairing block to level the transducer with the waterline. Also, since special tools and knowledge may be required to perform this type of installation it is best to refer to a qualified marine technician.

TRANSDUCER EXCHANGE

Other transducers are available as replacements for the standard transducer. You may exchange your new and unassembled transducer for another type by returning it to the address listed in Customer Support. Some transducers may have additional costs. Refer to the Accessory cata- log or call Customer Support for information.

BEGINNING INSTALLATION

Now that you have determined the transducer mounting method, you can begin installation of the 250DX. The fold out installation guide included provides detailed step by step instructions for installation of the control head and transducer. For transom mount transducer installations, you will need the mounting template at the front of this manual.

In addition to the parts included you need the following for installation and operation:

•A powered hand drill and various drill bits

•Phillips and flat-head screw drivers

•A ruler or measuring tape

•Pen or pencil

•12 volt power source (your boat’s battery)

•A 1-amp fuse

•A fuse holder (if you are wiring directly to the boat’s battery)

•Silicone sealant (for sealing drilled holes)

•2-part, slow-cure epoxy (for inside the hull transducer installations)
