Summer in Florida, need I say more?
I purchased twelve 24-volt Hella Marine fans about a year ago. They were about 50% off. I guess I could say, I got a hellava deal ~ groan. Installing them has been a back burner project since I bought them. They have been collecting dust. Well, the back burner project moved rapidly to the front burner as the outside temperature has hovered around the mid-nineties this week.

Cut small hole in vinyl ceiling cover, clean and drill a pilot hole (being very careful not to drill through the cabin top)
Repeat ten times. Stow the two extras for spares. Voilà! We have fans.
I tend to measure the success of a project by the lack of unplanned incidents and accidents. Very rarely am I able to complete a product without a run to the store, needing a tool, causing another project because the thing I was working on went horribly wrong. Things like fires or electrocution aren’t usually good. This project only required one Band-Aid. So, I would have to rate today’s work as a success.
