I used a piece of rubber baseboard material to protect the boat from the screw clamps. Lowes has it, or you can use a piece of plastic cutting board sheet( the thin stuff). Have extra pieces on hand, they sink when you drop them overboard, LOL
I remove the transducer setup to put the boat on on the trailer or to launch it so I don't hang the transducer on the trailer guides.
I leave it clamped and folded over when moving from spot to spot. 45 mph, no problem.
Mark Ridl with cornfield crappie will fix you up, his number is on his website.
You need minn kota shaft clamps for the large tubing and a piece of large tubing.
The livescope cable is VERY hard to install in the tubing. I used a couple wooden clothes pins to "wedge" the tubing open and work the cable into the tubing. It's worth the half hour it takes, cable is fully protected.
Hope this helps.
