Fixing holes and a crack

I just picked up a 70's 16' Sea Nymph that has seen some better days(it is down right ugly). The previous owner removed the remote steering to convert it to a tiller so there are holes from the old controls and also a bunch from where previous people mounted things. Also 1 of the holes has about a 1 inch crack running through it. What would be the best way to go about fixing these issues? I am moving up from a 92 14' Smoker Craft she looks good and is water tight but only a 15" transom. Hoping I made the right choice.

What size are the holes? I take a piece of aluminum and screw it over the hole. If I want it to be watertight I use 3M 5200 and either screws or pop rivets. As for the one that has a crack in it I would take a drill and drill the end of the crack. That will keep it from getting bigger.

Sorry by holes I meant about 1/8-1/4 where they had bolts through before.

I would just put a screw or pop rivit in it. You could use something like JB weld.
