I need to fill a couple of #10 screw holes from an old thru hull strainer for an engine intake (changing to a new pattern strainer). The holes do not penetrate all the way through the hull. Should I fill them with epoxy or a sealant like Sikaflex? I have heard that it is sometimes good to put a screw in the old hole and leave it there. Is that a good idea?
Thanks.
Thanks.
