Thank you Diesel45mpg. That's really helpful and reassuring. Seems like an easy fix. What has me confused and I can't check it until next week, is that the problem didn't occur until the last 20 miles of a 1550 mile trip. While I can't prove it sitting at my desk, I'm very suspicious that the problem occurred as my wife was "putting things away" preparing to dock
the boat and head
north for a month. I'm very anxious to see what got stored next to the compass. Because I'm new to the boat and to the system, I didn't know to check that possibility. If there is nothing there, it brings up a different problem as in "How did the system get so far off so quickly?" I will definitely post how the problem gets solved
when I get back after Labor Day.
Thanks for your input,
