Bought 2002 Larson 210LXi about 3 weeks ago. Trim indicator does not work. Previous owner said he thought it was a short in a wire. Spoke with a mechanic on phone--said he didn't suspect indicator, but a wire where it goes through the transom/stern (??) but said it's extremely difficult to troubleshoot. I realize it's next to impossible to troubleshoot over the phone (or Internet). But, what do you think? Has anyoneseen this? Trim is fully Functionsl --- Indicator does not move. Thanks.
