We have a new to family 22 ft shamrock inboard (1999) center console toted around on roller trailer. It’s not a downeast, but at least I don’t have to fish this year from the inflatable. Boat does not have a depthsounder. Any recommendations on how to mount a transducer? Can’t really do a through hull because the trailer rollers touch the entire hull as it rolls on/off the trailer. I know you can’t do a transom mount because of the prop wash. Any solutions for this?
