at speeds faster than 35 mph. Typically, a good transom location on aluminum boats is between the ribs closest to the engine.
3.The transducer should be installed with its face pointing straight down, if possible. For

Left, vee pad hull; right, vee hull. A pod style transducer is shown here, but the principle is the same for Skimmers inside a hull.
4.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 opera- tion.
5.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.
