Usually hull is tapered only where thru-hulls already exist. Factory doesn’t leave spare tapered areas for future upgrades. I don’t want to sound discouraging, but I think long and hard before drilling even a smallest hole that can sink me. And you're talking about 2" and trying to get it done at crunch time. See if you can re-purpose and re-organize thru-hulls in a way not to drill a new ones. Do you have an existent transducer you can take out? You might be able to install it on the inside of the hull with good results. There are plenty of articles on that. I had a transducer for Datamarine sandpiper in a non-tapered area and took it out to re-purpose the hole. I found that PO did not install it properly. RTV-like silicone was used and balsa was not taken out. I was lucky that area was dry.
In your case, you can definitely fast cure the stuff, especially in FL. Maybe get pre-made paste like interlux watertite. Mixing microfibers with west is a pain. 5200 will definitely still be tacky but that can cure under water. Also don’t forget to ask what would it take to undo what you just did. You can’t just plug a 2” hole if you decide transducer is no good.

Cure time depends on temperature. A heat gun changes the equation!

If I do it, it will be a 2 inch hole, and I want to do it right. The process I have got from the list over the years is in a nutshell,as follows: Once the hole is cut, and the core dug out to some range around the hole, you fill it up again with West System thickened expxy. Then drill it out again and proceed as with a solid hull. How long does the epoxy take to set? What would be a minimum time to budget for the whole process? I have never used epoxy other than glue.
