Time to end the thread and move on....
Thanks to all who have followed our progress and/or lack of plus all the kind words and encouragement.
So far all is working great.
The only 'major' problem was the AC condensation drain wouldn't drain to the shower sump. I had to raise the AC unit up 3/4" to get it to drain. With temperatures over 100 this week I also added insulation to the duct work to eliminate some condensation there.
Took a 3 hour boat tour yesterday. Engines and systems worked as planned.
Rudder position on the Simrad AP is a big plus!
