    Default WTB or Trade Jet Coupler Components

    I Just installed a new motor in my jet boat and had a problem with the coupler. The old motor had a flywheel and now I have a flex plate. The piece that bolts to the crank for the flex plate has a diagnal span of 3.75" but both my couplers are 3.125" which fit the piece for the flywheel.

    I'm looking for either the piece that bolts to the crank with a 3.125" span (to fit my couplers) or a coupler with a 3.75" span (to fit my mount).
    Willing to buy, sell trade or whatever, just need one.

    What motor do you have. BBC BBF ? Sounds like you have a 1350 PTO and your drive lines are 1310.

    The Bolt patern on a 1310 drive line and PTO is 3 1/8 in Diag . The bolts are 3/8 x 24 and should be 2" c to c on the short side and 2 3/8 c to center on the long side. A 1350 uses 7/16x20 bolts
