1972 20' Volvo straight 6 - original? Advice?

[CRSeacraft]

Thanks for the info Spareparts. I was hoping the triple-carb manifold set-up could be replaced with a mercruiser single in the future. The owner prior to the latest had the boat for 15+ years and was meticulous about maintenance. The motor looks beautiful and the drive operates and shifts with no noise or bump going in and out of gear. Only problems seem cosmetic (definitely needs a repaint in and out) and a small 1'x1' soft spot in the floor where the leaning post was originally mounted. Still don't know if I want to make her my next project but hanging around on this site is sure pushing me in that direction
