I run a Simrad chart plotter that I rely on for drive trim indicators. Don’t have mechanical indicators. Everything has worked fine for years until I splashed the boat for the first time two days ago. Drive trim works as it should but the indicators for each drive on all my chart plotters are not registering the drive positions. I looked at the obvious things that I could see but I’m at a loss. Anyone have any ideas where to start? Seems suspect that both drives stop indicating at the same time. All the other information from Smart Craft is shown. Only drive trim position seems to be effected. The only change I made this winter was connect the passenger side Simrad to the NMEA2000 network. I’m wondering if there is a trim setting on the Simrad that is causing this? That will be my next item to check when it stops raining

Problem solved.

what was the solution ?
