Does anyone have a good or proven idea to seal off a below water line thru hull hole?
I am reconfiguring my livewell system and by doing so I have an extra hole in the transom I don’t need. I thought of taking two solid rubber stoppers, drilling a hole in each, and using stainless steel hardware to bolt them into each end of the existing thru hull. I would also use marine sealant for good measure. Comments? Are there any other, easier ways to do this?
Thank you,
Chip
