Recently broke mount for transducer on canoe while putting it on the trailer yesterday. Any mounts that work for the garmin 4dv transducer without modification?

What style mount were you using originally? Arm style mount over the side or Scupper hole style? I have a striker 5 and from my research it seams that most of the transducer mounts available are designed for transducers that have that one raised mounting hole, which Garmin seems to not use often. Without modding it I think your best bet would be in hull. Kinda stinks though, heard quality can be mixed and water temp is off the table that way. Personally I went for the Ram transducer arm mount and switched out the stock bolt with a longer one and added rubber bushing to fill in space. There's a video on youtube that shows it. Good Luck
