redbug said:you can get a size group 24 or27 deep cycle battery. The 27 will be bigger and give you more on the water running time. If the trolling motor has clips on the ends of the wire you can go straight to the battery if you are going to make it a permanent mount you should use a 40 amp marine breaker. the fish finder can be hooked straight to the battery with an in line fuse. you might get a little interference from the trolling motor if you use the same battery but it should be okay

I have 2 running @24 volts to my 74lb minkota on the ranger and 1 everstart crank for the 200hp and on my smokercraft I just have 1 running my 40lb minnkota trollingmotor and a everstart crank battery for the 50hp outboard. I would just run your fishfinder straight to the battery with an inline fuse, if you dont have a fusepanel. the fish finder doesnt really draw that much off the battery, but if you are concerned about that, just get a cheap motorcycle battery @12volts to run fish finder and maybe a deck light.
Just my thoughts..
