Hello fellow boaters,
I hope I am in the last stages of a major rebuild on my boat . When I purchased it the 2 transducers for depth and speed had been damaged. One hole had been filled with a brass seacock, the other hole still had the damaged transducer in it. I am trying to decide whether to fill in these 2" holes permanently or use one for my depth finder and leave the seacock in the other. I would appreciate any thoughts on my options here

If you're going to put a depth finder in, then use the existing hole (hope the new transducer fits it). Then I would leave the sea cock in... might want a wash down or macerator later. Welcome to CSR!

I had mine filled in. I installed a new transducer in floor of bilge. Fiberglass shop just sands a little spot on floor. Put a spoon full of resin and push transducer in. I did mine works great been 4 years. Slip neighbor used silicone .

According to the glass folks in our area, the proper way to fill the hole is to sand both sides at an angle so that there is a lot of surface area on the inside and the outside of the hull, then use fiberglass mat and resin to fill. The finished product should look something like a barbell only flatter.

After reading your replies I am leaning toward filling in one hole and leaving in the seacock. Would polyester resin be ok to use as filler or do I need epoxy?
