Condensation in Gauges
My new Catalina gets condensation in its engine gauges, primarily the tachometer. Today the outside temp was in the 60's when I went for a sail around noon. There was enough condenstion in the tach that I couldn't read the engine hour display ( could read the tach okay, but there's a fair amount of condenstion in it). I keep a Sunbrella cover on the helm.
I brought this to my dealer's attention a few months ago (2007 model 309) and they said this is normal.
