Hi Peggy, My Irwin 37 has 2 completely seperate head systems and all the 1.5 inch hoses need to be replaced. The rear head works fine(rebuilt) but all the hoses look original from 1974. Has 2 bladders(ok) and 2 non working manual pump outs(unrebuildable due to corrosion). Should I keep it the same setup or can I combine the 2 to save on materials and simplify? Should I keep both heads intact or take one out and use the space for storage space(closet)? I plan on longer trips later on but at this time just run out in the gulf for day or overnight trips. I will post pics later. Thanks, Jim
