Wow, a 4" hole saw creates a lot of dust! Last night, I drilled three 4" holes and installed the pull out tubes.
Here's the two holes for the vents in the walk thru area which is the factory location. I put two layers of masking tape on the gelcoat and measured about ten times before finally drilling. I ran the 4" hole saw in reverse all the way thru. As you can see, it makes a perfectly clean hole - the chip in the bottom of the left 4" hole was caused by a protruding head screw in the pull out tube body which I caught on the edge of the hole after test fitting the tube then pulling it out. The chip in the rightmost screw hole was because I tried to put the screw in before chamfering the hole - doh!. It all gets covered up anyway.
Here are the tubes installed. These are the new style vents - the nice thing about them is that you can twist the vents to open and close them.
