So on my 1996 wellcraft excel 21sl boat my trim gauge doesn't work. I noticed when I did my bellows and gimbal bearing last week there was this electrical device on 1 side of my outdrive. I believe that is my trim sender. Where the wires go into it the rubber around the 2 little wires is split and cracked. So does this mean that's my problem and water got in it and stopped it from working. I rather ask on here before I go out and start buying different parts I don't need. Or could my gauge be bad,or a bad wire or ground or fuse.again I rather ask the questions now before I start replacing parts I don't need to replace. Thank you dan
