Default Maritime Boats and Thru Hull Installation

Own a 2008 Maritime 18 Defiant. Preparing to install an airmar thru hull transducer and checking to see if anyone has installed one recently that could help me understand what to expect when I drill into the bottom. According to Airmar it makes a difference if the hull is cored or not, as to what size hole to drill. Any input would be greatly appreciated.
Thanks

easy enough to find out, call the manufacturer.
I had a 2007 16' Maritime and it was foam filled under deck but not cored.
If it is cored you will have to scrape out an area of the foam around the hole and epoxy fill it

I had a 2004 20p and did the same. The hull bottom was solid glass. It was a real PIA working through the small oval hatch. Make sure you choose a location that you can reach. I first installed a p79 which was excel ant and then switched to thru hull and it was no different. Airmar told me its the identical transducer. Save your self a ton of money and time and do a p79.

I have a 2001 1890 skiff, the hull is not cored, its solid glass. I'm in the process of putting a new deck on now, was going to go this route but decided against it as I was on a budget. Had a fiberglass guy say he would replace the deck for $2500 (wood) and that price shot up to over $6k (with wood) so I told him to pound sand, could of gone somewhere else for 5k and had it done in coosa but the shop never called me back.

I took the boat back and decided to do it myself. and I found ALOT of issues with the work the original guy did. Had to fix all those issues first. UGHHHH... If you want it done right do it yourself.

BUt I do love this hull, its one of the last true Paul Hureau made hulls.

Update! I did call the previous owners of Maritime. They were very helpful. The maritimes are solid glass hulls, approximately 3/4" thick. Drilled the hole for the thru hull and had no issues with interference based on the recommended placement. Finishing up the install and happy to share pics if anyone is interested. In general very happy with the overall install including interfacing to the Suzuki DF115. Also purchased a new Scanstrut enclosure for the Garmin 1042, which is really nice. Can't wait to get to Harkers Island/Beaufort and utilize this new technology. And of course fishing in the Chesapeake Bay should be great. I'll know more about that in the next week.
