I just replaced the sending unit for the jack plate on my 2013 Puma FTD. Seastar was not much help with troubleshooting. I can watch the gauge move when the arm moves but when the arm is bolted to the jack plate it is way off. Does anyone have any experience calibrating one of these plate gauges? My closest dealer is over an hour and a half away, if I need to take it in I will but I have to think this is something easy that Im missing. Any help would be much appreciated. Thank you!
