Install New Humminbird Fishfinder

My location is west paducah,around the airport. I've got a new fishfinder as a gift. But I can not put it on my 14ft. flatbottom--25hp. merc. I have a unit on the boat now. This new one is much better. I am diabled with little money to pay, and I want to take it out on the water after it's put on the boat. There are some dealers around the lake and guys that can do this. Who can help me, for a reasonable price? Thanks guys

If i didn't live so far away i would do it for you. Hope you find someone

Do you know how to install it? I have no clue but am willing to come help. If you can coach me, we can install it together.
