We are removing a fairly new (2013) Power pole from the transom of an '01 Waterman 18 we just acquired. I assume there will be 5200 involved, so we plan to remove the through bolts, support the Power Pole, and saw through the sealant with braid. I'm not sure what the sealant residue situation will be, but have been advised to scrape it off with a sharpened putty knife. There will then be 6 through hull holes (4 mounting holes and 2 line holes) to fill and repair. Our plan is to drill the sealant from the holes with a slightly larger bit, chamfer the edges of the holes and then back them on the inside of the hull with taped on acetate. We plan to then fill the holes with 3M high strength marine filler (with fiberglass strands). The next step after the filler sets, is dish the filled holes slightly with a Dremel tool, sand lightly, then wipe with acetone, then apply color matched gel coat with wax.We will probably cover the gel coated spots with taped acetate to produce a smooth, level surface. Then, some degree of fine grit wet sanding and polishing will be in order. We will treat the inside through hatch holes the same way. Any scratches caused by removing the 5200 will also be sanded and gel coated. My question is, to you fiberglass gurus out there, are these plans the correct way to go or is there a better way? Any advice or corrections would be much appreciated.
