extreme care if mounting the transducer inside the hull, because once it is epoxied into position, the transducer usually cannot be removed. Remember, the transducer installation is the most critical part of a sonar installation.
Recommended Tools and supplies
If you prefer the option of routing the cable through the transom, you will need a 1" drill bit. A transom mount requires use of a high quality, marine grade above- or
Tools include: two adjustable wrenches, drill, #29 (0.136") drill bit, flat-
head screwdriver. Supplies: none.
Tools: two adjustable wrenches, drill, #20 (0.161") drill bit,
screwdriver. Supplies: four, 1" long, #12 stainless steel slotted wood screws.
Tools: two adjustable wrenches,
Tools: these will vary depending on your hull's composition. Consult your
boat dealer or manufacturer. Supplies: 100 grit sandpaper, good quality epoxy adhesive.
Selecting a Transducer Location
1.The transducer must be placed in a location that has a smooth flow of water at all times. If the transducer is to be mounted inside the hull, 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.
