Has anyone ever rebed a hatch on aC350? I'd like to know what was used to bed it originally. Trying to figure out how difficult it will be to remove the hatch before I get started. Thanks for any input.
C350 hatch rebedding

Ok great! That encouraging. I had to rebed a hatch once years back on a Wellcraft cabin cruiser and it had 5200 on it. I prolly should have gone to counseling after that.

Howard, unless you are the original buyer of the boat from Catalina, there is no way to know that a previous owner did not change the hatch and use a different caulk.
You will be lucky if 3M 4000 was used. It could be 5200 which is tenacious but can be conquered using a release agent, heat, and or a putty knife. You will be really lucky if Butyl was used.
As guidance I suggest you make sure your leak is from under the hatch and not a seal or the hinges of the hatch.

Use BedIT butyl tape. It's a synthetic blend made specifically for deck hardware. It's also a lot less messy
I would use butyl tape (Bed- It) ONLY if the hatch is tru-bolted. You need a lot of clamping force to make butyl tape work seal.
My O’Day 322 hatches are just screwed into the fiberglass with screws. I tried butyl and it wouldn’t seal. I just pulled one an rebed it with something like Sikaflex.
A caulk/adhesive will work better if the hatch is held in with screws into the fiberglass deck.

Butyl can take patience. In some cases you must tighten the device to a reasonable level, let the butyl settle and then retighten after waiting a bit
