I am going to add a trolling motor to my toon. I am also going to put a graph on it. I was wondering should I run them on seperate batteries or from the same battery. Why or why not?

I was thinking of just running the transducer and temp to the trolling motor. I see that you guys do them seperate is that because you are not allowed to run a trolling motor at your tournaments or is there another reason?

Do you guys think you will ever allow the use of a trolling motor in your events? I have a bad back and can not row all day. I would love to fish an event or 2 with you guys if you ever did.

I have the ODC 816 can you tell me what graph will fit and what ones to avoid. I am not going to get the top of the line unit something in the 80 to 150 range should work great for me.

Thanx for any help.... Rodger
