I have an old aluminum boat that has 14 holes in the lower right corner of the transom from the various transducers that have been mounted. I'm replacing the transom wood and had sealed it nicely with epoxy. Two or three holes are actually below the wood and had screws with sealant plugging them. I've gone to the trouble to carefully sealed the wood, even drilled out all 12 of the through holes 1/16" oversize and sealed the hole ID. I am reluctant to fill that many holes with screws into the wood.
Do I seal the extra holes with marine tex?
Seal the holes with 5200?
Do I install new screws with 5200?
Is there a better way to seal them without welding?
Thanks in advance.
