When installing my Smart Tabs I made an error in placement at first and to make a long story short, they're on fine, with one minor problem.....there is and extra hole drilled in the transom. It is open through approx 1/4" fiberglass (there is no wood backing in this area).

I used 3M 4200 to hel seal the Smart Tab hole, but I didn't use it for this hole for two reasons. 1. I think I've read here 5200 is the better filler. 2. My 4200 has become so gummy to work with I can barely get any out of the tube and it wouldn't be easy to fill a hole with it.

Is 5200 the correct product? How best to apply whatever i use? I can NOT get at the inside of the hole as it is under the floor.

Thanks a ton. This is the LAST thing I need to do to get my boat ready for the water!

Re: Filling in small drill hole in transom

OK, say I use Marne Tex then. How do i get it to fill a small hole properly? Do I need a syringe or something? Or do I just use a putty knife and keep workingit into the hole?

Is marine Tex a on or a two part product?

Could I use Epoxy resin if i have some on hand?

Thanks for the help.

4200 and 5200 both start to cure the minute they are opened ..it says to use up ..wrapping it up tight and in the fridge slows the process, but once opened, its starts to cure. Toss that old 4200.
Anyway...I had a bow/winch hook that had waddled out the hole on a boat I just got done with. I simply opened a new tube of 5200 and filled it where I could, and smoothed it around the hook. 5200 will need a week to 10 days to cure, but it so simply to work with, stays slightly flexible, and I would just squirt some in there and forget about it. I think solid Marine Tex is expensive overkill on this. 4200 will work too...faster cure time.
Now I crank a 16 foot Flatbottom with a big Merc on the trailer and it does not budge or leak. Should fill a hole for life with zero problem.​
