I have a 3 month-old Puma. A couple of trips ago, when I started up the engine, the trim indicator on the Smart Craft went haywire. The trim indicator would jump from 0.00 up to over 4 and back down, jumping around haphazardly at every setting in between, making it impossible to read the true setting. It kept doing it until I held down the + and – simultaneously for 10 seconds, resetting the Smart Craft. It seemed OK for the next trip, then started it again the last time out. Any suggestions?
