    Default BRP's web site

    Does anyone know if the part numbers posted on BRP's web site are current or could there still be SS's in them?
    How up to date are the numbers?
    Thanks

    I believe the dog was a running change as the original was being damaged on over run in the corners.
    So it came out years after the 75/Nitro was finished

    The heavy duty clutch dog was released for the 1990 race season, Pt.No. 336446 it may still be obtainable from Seaway Marine.

    The production tunner length for the SST-60 is 7.69 inches (195.32mm), from the bottom of the adaptor to the end of the meg.

    Default late model 70hp flat top carbs

    Fred

    Have you ever tried the late 70HP (92 to 98)flat top carbs on a 49ci?
    What bore size are they?

    They didnt use them on the SST 60...maybe there's my answer?
    Cheers
