Transom Angle

[macojoe]

when i got my new fish finder it came with a shim so that you would get a better angle.
The Instructions says if you have a angle of ?? then you should use the shim.
I did not use it, as I had anough play in it to get it stright up and down with out it.
But try it with it and then with out it and see what fits better. Thats what I did.
You would think I would n what the angle is since I added a bracket??? But I have no idea, sorry
