Hi all, hope some one else have not posted this question, as my search came back empty. I recently purchased my 2000 carver 356 aft cabin. As I am getting more familiar with it I am finding out some minor issues. latest one is the depth gauge is not working. It was fine when we purchased it. After purchasing we docked it for about 3 weeks. When purchased, the boat was off water and bottom was painted before we signed the papers. So my question is, is it possible stuff formed under the boat at dock that's causing the dept gauge to not show anything? or is there some switch that I am missing? or fuse hidden somewhere? loose cable? if so where would that be located in the hull? I just remember when the engine started it went on first time 3 weeks ago. But now starting the engine shows no life in the unit. No lights, no displays. Any help is appreciated. Thanks in advance.
