something to consider is the "stern mate" and the "sternsaver". I used the "sternsaver" on my Tracker PT175 to mount my LLS-1 TD, and has worked very well for the 6 months since I installed it. both are a glue on type (no screws), have no opinion on the stern mate but am considering getting another stern saver and lower my 2d TD down to the step on my transom where I mounted the LLS 1 but will have to make sure I won't have a clearance issue or possibly blocking the SI image if I move it down.
GO BIG ORANGE !
I meant to behave, but there were just way too many other options available at the time.
