Deep dent with a small crack (read leak)

My new to me Alumicraft Angler has a small but deep dent in the bottom left corner of the transom like where someone backed into a rock. I found this this weekend after noticing water in the bilge after the boat had been sitting in the water for 6 hours. The crack is only about a quarter of an inch long in the center of the dent and this is in a very strong part of the transom being very near the corner so I doubt there is much flex there. What is the best semi permanent fix for this leak short of having it welded.

I like this stuff for those kind of fixes:

You can completely fill your dent and it'll squeeze into the crack as well. Full cure in 24 hrs., but will setup and cure underwater.

About $5 a tube.

I've never seen that particular epoxy before. Looks like it may be the ticket and I can even fill in the dent with it and just touch up the paint. I'll have to check around Wallyworld and AutoZone etc and see it I can find it locally.

I've never seen that before either. Looks like the ticket for a lot of stuff on the water.

No luck finding the Loctite locally but found Marine JBweld. Never had much luck in the past with JBweld products but will see how it works. I ordered some Locktite off Ebay just in case!

The Loc-tite marine epoxy is available at Home Depot in the adhesives section of the paint dept, it's in the same place in some of the Wal-marts too.
