1. I have a 2010 PUMA FTD with a Detwiller Hyd jackplate.My gauge needs adjustment. Shows 1/4 up when all the way down.Is there a way to adjust this gauge?2. What size are the nuts that is on the underneath side of the deck that holds the TM mount on. I need to tighten, and pliers are not really the best tool.3. I broke my Lowrance temp sensor (in half) that is mounted on the transom under the jack plate that hooks to the flasher. How do you fix that?
