I was reading in the manual that it was suggested to drill a 3/8" hole in the aft end of the mast about 1 1/2" up from the base for drainage. I expect that I am collecting water in here and would like to provide this drainage, but wanted to better understand exactly where to drill and what I will encounter inside before doing this. Just had a few questions:
  • Should the hole be drilled at the aft end right in the center
  • At 1 1/2" up from the base will I be drilling through the mast heel fitting or just above it into the cavity in the mast. Not sure if that is the correct term but I'm referring to the insert (assume is aluminum) that fits up inside the base of the mast.
  • The other thought I had was concern over contacting the wire harness in the mast with the drill bit, but assume/hope that is coming through the heel fitting in the center and if I know how thick of material I'm drilling through I'll just put a stop on the drill bit.
Insight from someone who has done this would be appreciated.

Keeping busy with boat projects here in Michigan hoping the winter will eventually come to an end and Lake Michigan will be fluid again.

Best regards,
