You're very correct. Drilling the hole is stressful, first hole I've drilled in the boat! But I'm also a retired construction guy. I used a cordless Makita, it has 2 speeds. I choose the slower speed (more torque), you can set the clutch on low also. It's hard material. Just be very sensitive (insert sexual term here) to how it's going. When you break through, the piece you're drilling will break loose and enbed itself in the hole saw, time to back off! If you're not familiar with the drill and process, practice on some other material. You'll figure it out after becoming familiar with your tool. Patience grashopper.
I have actually drilled a 4" access plate in the main floor (just aft of the raised table mount area). This is about the mid point between the bow storage area (where you mentioned the damp carpet) and the sump pump access cover. I use it to ensure water is not standing on the finished fiberglass subfloor (the sump floor if you will). My table mount (V278) is on a raised area from the main floor level. (the floor you would walk on) so it is a seperate compartment under the main floor. Every couple of weeks I will unscrew the table mount and use that to check the sub floor area just aft of the bow. Between those 2 access points I can get to all of the sump floor level to ensure it is dry (or remove any water).
For firecadet613....this is the area where water was standing unnoticed for I expect quite some time by the previous owner. It was discovered by my marina mechanic when I asked them to investigate the smell. I know he used access through the table mount to get to the subfloor level and really scrubbed it out. This episode is what makes me so aware of water at that level. Thanks to other members such as Off-Piste and David, I realized there was yet another potential area for water to go undetected (between the sump floor and the keel). I"ll be getting the hole saw ready for spring
Have a good one!
