I bought a 1988 4winns 205 Sundowner; omc 5.7. The original engine had been replaced with auto, had a marine jasper installed, along with upper unit-therefore I have no #'s to order an original manual. From what I see, the # 574APRGDP, or GDE should work? (4bbl,p/s,righthand). Thanks, this place is a knowledge base.
