I certainly would not recommend drilling from the inside out at all. You push on the drill to get it through, so when you get to the outer gelcoat area, the pushing could cause it to crack and chip away. Tape is a good idea for drilling though. A cordless screwdriver makes mounting the module much easier. Other than that, the tools that have been mentioned. By the way, it is a 2" holesaw that you need.
