Thanx for all info. I also asked Mark form Cathouse what should I do. His response was: “Water in the mast: take the upper cap off… drill hole thru the water dam…. Drain & reseal….. & rivet cap…”

I thought about removing mast rotating arm. There are 2 screws going through the mast and use those holes to drain it.

OR

Drill small hole in the casting – base of the mast and drain.

Thanx
