    Iím curious why guys donít go that route.
    I know itís on my list of options at the time the next boat comes.

    I wish you could also get the LT4 from indmar

    If you can do the wire harness to adapt a tuneable ECM, you could make a bunch of $$$$$

    Thereís all kinds of places Iím sure I could get one for an LS/LT. I know I can for my 409 6.0
    But Iím not too into it with this boat, next for sure.
    Iíd prefer the GM engine next go around. But that pretty much takes me away from an indmar supplied brand.
    Iíd love to stay with Supra.
