The fuel tank hatch will be recored. Sealing a deck hatch with 5200 would be impossible to remove. 4200 only slightly better but probably still won't come out unscathed. It's screwed down and doesn't need adhesive, just needs to be water tight, and easily removed and reinstalled/sealed for inspection if needed. Silicone caulk for that.

Sika 291 works great!
