filling below water line screw holes

[Five O'Clock]

Hello All,

I'm moving my transducer 6 inches to the starboard side of the transom so I'm going to have 2 open screw holes below the water line.

Can I fill those open holes with 3m 4200 or should I use something else?

3m 5200, Marine Tex, or epoxy would be better, IMO.
