They had different engines too, earlier ones with the Westerbeke and later ones with the terrible Volvo 2003. All with V drives.
FWIW, most (all?) early models came with all fixed ports, with mid to later models ending with eight all opening posts. All opening ports were plastic Beckson, anything else an owner added. 1986 was the last year of production for the 36T, a few were made on a custom basis after 1986.
