Hello Skipmac
R.W. from Pensacola, We have the 422 Island Star. Have seen the Mi Prescription ketch in Panama City. It needs a lot of TLC! Have just put in AC and a Genset in IS. GREAT boats!! We love ours and yours is literally a fish out of water. I think if I were going to re-power I would cut the cockpit floor out and re-glass it when the new engine was back in.
