My forward AC keeps tripping... Any thoughts? I cleaned out strainers and boat has not been in sea weeds or anything like that. It seems to trip every 5 hours or so...
 
Sounds like a weak c/b. Go to WM and buy a new one. Try this first before anything else. Over time c/b become weak and trip with the startup load. I had a simular problem, spent a lot of money with a "pro" and ended up being a $40 c/b.
 
410DA should have 2 zone A/C. Try swapping from the 2nd unit and see if it works fine. This way you'll know for sure that the breaker is the problem.
