Here in the next couple weeks I will be adding a binimi to the boat(no tower), I have read all I can find on here and the rest of the internet about how to do it. I have a couple more questions if someone who has done this before can add some input. Ive read to tape it off with blue painters tape, drill holes in reverse, do a smaller pilot hole first. Sound about right so far?

Now after the holes are drilled do I need to add silicon or a pad of some sort so water doesnt get into the holes? Also is there a particular type of bit that I should use or will just a new sharp bit due?

If I am missing anything or any advice I will gladly take it as I am not excited about drilling into the boat, excited about the addition just not the holes..haha

Thanks for the input.
