Actually, the thickening agents in epoxy, whether it is colloidial silica or some other high-density filler, serve two purposes when doing this type of repair. First, they thicken the epoxy to help it stay where you put it, instead of dribbling out—now this isn't so important when the hole is on a deck, but if the hole were on the side of the boat, it would make a big difference. Second, they do add quite a lot of compressive strength to the epoxy resin.
For instance... imagine a bowl of jello. That's epoxy.. push your palm down into it... not too hard to do is it. Now imagine the same bowl filled with jello that is filled with peanuts. Now try and push your hand through the jello... Now, do you think it is easier or harder to do than when it was just plain Jello???
You really should be using thickened epoxy for potting the holes. Almost all of the books and most of the people who write about it, including the people here on Sailnet, say use thickened epoxy for a reason.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
