    mr1 crankcase

    anybody know if the cylinders are steel? i have a 06 230ho that i need a crankcase, ive i found a non ho crankcase and from what im reading they are the same except bore size, so id just have to get it bored out. If they are steel of course.

    The fx is Steel and The fx ho is NIKASIL.
    You can test with a magnet in the bore.

    A FX140 Crankcase is not the same as a FX HO. A VX110 crankcase is a closer match than a FX. I have some HO cases available if you're still looking.
