the pirahana 2 finder is good and u can run it off the same battery that the trolling motor runs off of, just be sure its a good quality marine deep cycle battery, i used to run the same setup except i had 3 batteries on board, i would be out for a long time thats y i needed the extra batteries, but i didnt find that the fish finder drained the battery that much runs about 80 bux at wall mart of k mart, B&W screen with a back light for low light viewing and water resistant, rain and spray doesnt kill it, ive had mine for about 6-7 years and it still works, also u can mount the ducet on the bottom of the trolling motor with a large hose clamp and secure the cable with zip ties on the motor shaft, and mount the finder display on a piece of 2x12 and on the bottom u can screw on some velcrow to the bottom of the board and to the bench in the boat where viewing is most convienent. note may have to put some 1/4" screws threw the velcrow on the bench seat to better help secure it down. this allows for easy removal. also seperate wires for the battery and ducer. i bought large alligator clips for the power wire easy on easy off.
