Default Transducer Upgrade Needs Bigger Hole

I'm moving up from an AIRMAR through-hull with a 33mm shaft from one with a 31mm shaft. My problem would be a 31mm hole in my boat. I need to make the hole bigger without destroying my hull. Trying to over-drill an undersized hole in wood is usually a disaster and I don't expect fiberglass to be much better. Ideas?
