I recently acquired a 1982 Starwind 223The boat sat on a trailer for 4+ years, but seems to be in relatively good shapeI need to remove the retractable keel (cast iron 775 lbs)I'm stuck on how to do thisThe pivot pin seems to be water sealed by installing a one inch pipe nipple with a cap into a plate inside the keel pocket. Of course the caps are rusted fast. The caps are so close to the hull bottom I can get a wrench around them. I assume there is a pivot pin inside the nipples. In addition, there are 6 stainless steel bolts around (very close) this nipple that I believe hold the plate inside the pocket to the hull.Has anyone removed the keel and resinstalled it?Would appreciate any advice/experience/drawing, etc.Thanks for your timeDan Wien
