I had to remove my bilge pump to pull the flywheel off and I noticed that it was attached with screws that went threw the bottom of the hull. Also noticed that there had been previous screw holes that had been filled and when I put a light over it you can see the light threw all the previous holes. Was wondering if I should just fill the holes or if I should lay some fiberglass over it, to reinforce it. Also wondering what I should use to fill the holes?
Thanks
