Unfortunately, opening up the hatch is a whole new world. How it all started for me. Hatch needed to be recored. All fuel lines upgraded to new methanol standards ($10/‘). The “$10/gallon” rule of thumb seems to be of the Baby Boomer era, especially with new tariffs on the aluminum. Go at least .125 thickness over standard 0.90 (should in theory last longer). The foam around tank will reflect where water held and corroded tank worse than where foam was not in contact with aluminum. Cut it out using a sawsall, but be careful determining if there is a floor in the hold. My ‘79 20 had beautiful gel coat finish inside. Be careful. Otherwise, not a bad job. As said, triple your time, money and beer budget. Or BOAT: Bring Out Another Thousand. A pic may help you see how to raise, pitch console out of the way without disconnecting or removing. Hope this helps.
