Catalina direct sells the remounting kit with the longer lag screw to go deeper into the post. It should be pretty self explanatory. In addition, since I didn't think the longer screw and epoxy were going to hold strong enough, I drilled holes in the plate at the back end and installed bolts through the plate and deck that ended up right behind the post in the cabin. Had to be careful though, the bolt heads are verrrry close to the bottom of the mast when it is up, I had to make sure that they didn't interfere with the mast while raising/lowering and while in position. A healthy dose of 5200 everywhere also helps
Be very carefull where you use 5200. This product is a one way street, and the things you bed with it are not going to come up again. This product is used for hull to deck joints etc. where NOT comming apart is the issue. In the right place it is great. Just be sure you know where that is.

I agree with Dale, this is not the place to use a permanent sealant, no doubt you'll have reason to remove the tabernacle at some point. You'll find if you use 3M 4200 or equivalent Sikaflex or Boatlife to re-bed you'll have one heck of a time removing the tabernacle.
On my old-style boat rather than use a longer 1/4" lag bolt I went to a 5/16" of the same length, I also drill through the front hole over-drilled it filled that hole with epoxy then re-drilled and use a bolt with a nylock nut on the inside topped with a acorn nut. I never had any trouble with it and use I removed three times while I owned the boat.

It would be interesting to know if you still have the aluminum tabernacle with the tangs on it. The mast had a captive stainless steel rod to engage the tangs for a neat and speedy mast stepping.
Mine lasted a couple seasons until I had trouble raising the mast (those were my early days before I worked out how to use the running rigging as a hoist for stepping the mast). The result was the aluminum tangs broke off cleanly and raising the mast was made infinitely more difficult before I got a stainless steel replacement.
The center hex head screw goes through the deck into the compression post inside. If the screw is loose in the wood, an old woodworkers trick is to push a thin dowel (like a toothpick) into the hole then reinsert the screw. The other fastener is a bolt through to an acorn nut inside and that is easy to do. The bedding (already discussed) will keep the deck water tight and the tabernacle firmly secured.

Speaking of woodworker's tricks, you can completely drill out a damaged hole in a wood post and tap a glue-covered wooden dowel into the hole. Give it 24 hours to cure, then you have a solid hardwood foundation to re-seat your wood screw into.
