    I would take small pieces of fiberglass matting and soak them in poly resin. They will fill the holes nicely and give it some strength. Any filling/fairing that needed to be done could be done with poly resin mixed with cabosil to thicken it up. When it cures, you can sand down to give some space for the gel coat. I bought some of the matched gelcoat paste kits. I haven't tried them yet but I think it would be perfect to top off your holes.

      Make sure the holes are dry then do as wefivehodges suggests. The gel coat repair kits work well and with carefull mixing you can get a good match.

        i was thinking to put a rouded wood with glue to fill the hole then fiberglass and gel coat.

        the transom is thick

          The matting will fill those holes very quickly. The would might offer similar strength but I think the matting might be faster start to finish, unless you had wood plugs of that size already cut, maybe wood dowels of that size. I would still go go with the fiberglass. I think it would be easier and faster.

              Above or Below the water line?

              I would soak wood plugs in resin before inserting.

              Marine Tex is a good filler as well.

                3M-5200 sealed the holes in ours when we fixed the trim tabs.. its great stuff.. we did that stuff and the fiberglass for a tangerine size hole near our props.. the stuff is a wee spendy BUT worth every dime..

                  This is my preferred method: drill out the hole one size larger to ensure you have 'clean' wood to seal. Then fill the hole from both sides with polyester structural putty (Fiberlay is excellent). If the hole is small (~3/8" or less) then Marine tex is also good. Marine tex isn't appropriate to fill larger holes unless you cover with fiberglass both sides. Structural putty saves you from patching with fiberglass layers afterwards. Then when it's all set, use a Dremel tool with appropriate bit to carve out about 1/8" well beveled into the gel coat. Mix some gel coat and fill.

                          Andrew, if that black anti-fouling bottom paint is conductive, you will want to remove it from coming close into contact with your metal components, such as your Volvo transom shield.

                          1" or greater would be recommended.

                          Otherwise, this can bring the metal components into the path of the galvanic action, and will eventually destroy them.

                              when i trying to sand off the paint is very powdery.is this normal for bottom paint ?

                              do i have to sand it off to the bare gelcoat like you said min 1".

                              im going to sand off the bottom paint and the black paint from outdrive.the outdrive im planning to spray with volvo silver.
