It has a Perkins 6.354 . Originally as a workboat I think it had a Detroit .The PO took the old motor out and put the Perkins in thru the roof . The builder built 2 of these 32's and 3 that were 36 ' .He built about 40 26 ft tugs .Have been admiring William for a while now and love the lines of that beauty. What motor does she have?
