I would not change how the crack has settled, or has become. The overlaying of the material will in fact make the area and your repair stronger, than if you were to even up the edges and then repair it. Removing material and then evening up the split, would allow for increased pressure on the split/repair area, should force ever be applied again, imho. So long as repairing it with a bead or 2 of this product is not terrible unsightly, you're good.
I recommend something like this (and whatever you do, don’t end up using silicone. Please. lol)
“Stress caused by shock, vibration, swelling or shrinking is
effectively absorbed. fiberglass deck to fiberglass hull, wood to fiberglass, portholes and deck fittings... above and below water line.”

I emailed the guys at Catchsurf for tips before I applied it. They said to clean the wax off by blowdrying it. I also cleaned the area with a little turpentine before applying.
the guys at Catchsurf also recommended 3M 5200 Marine Adhesive but I also got some Loctite clear silicone gel waterproof sealant when I couldn't find the 3M at Ace hardware. So I used a combination of both. The 3M I put all over and the Loctite I put on the perimeter of the pads. On the left and center pad, I put two perimeter layers on the pad (since the loctite squeezes out in one long bead), and then smeared a bunch of 3m in the middle. The right pad I fucked up on because it was the first one I applied, and I only did one perimeter layer and the bead didn't connect with itself. I was also too lazy to take the fins out of the board, so I didn't put any weight on the board to hold down the kick, which kept popping up.
This time around, I'm putting a couple 5 lb weights on the kick.
It's pretty common stuff, you can probably get it at a hardware store, especially in Alaska.

Maybe that will help you determine where that pipe goes? Otherwise there are PVC leak kits that are better than flex seal:

Good luck!
