I have a 87 Formula 272SR-1 with Alpha drives and 350 magnums and would like to up grade engines. Would these motors be compatible with the shift interuptors on the Alpha drives. Also the wire harrness will they plug into a 9 pin plug or do I need to adapte.How do you think they would push this boat. I am very interested .Thank You Richard Klompstra e-mail nklompstra@sympatico.ca. (ps where is Ruby MI. I live across the border form Marine City MI)
