I glued mine in, I actually did a google search for where to mount it and it ended up bringing me back to the moomba website, imagine that. I mounted it between the speed paddle wheel and the center of the boat. I was really cautious about putting it there because the hull appears to be around a 5-7 degree pitch. So I did the math and realized that a 5 degree offset would be very small even at 100 foot deep water. I am really only concerned at like under 10 foot of water so the difference is only inches. I wanted to get it mounted so I glued it in there. It actually took me longer to find the formula then it did to actually hook it up and run the wires.

I do have one question though, I assume you need to be in the water for this thing to work right? I have the boat on the trailer and I powered it up and there are just lines on the display. Can someone just confirm that it wont read anything unless i have the boat in the water
