I am selling an OEM Seadoo in dash digital depth sounder. I ordered this new off ebay and tried to install it on my 2005 Challenger 180, and it wont work. The mechanic told me we could wire it in to work but that its not made for my boat. This depth sounder is in-hull mount. So if anyone is interested please contact me. I am trying to figure out exactly what jet boat it goes on. Its very nice and Im not happy that it wont work in my boat!!
