What year? My Taiwanese tub has stainless tanks and 3208T/As. Love our tub and the engines.
Welcome
By default and unless otherwise replaced, 30 year old Taiwanese Tubs have black iron tanks.
It's a 1989 model. The broker claims the tanks are steel, but I could tell they were stumbling when I posted that question. And to the unknowing steel=iron.
If you have inspection holes it is easy to tell. Make sure you get a survey and ask your question. Get the tanks cleaned and fuel polished.
