    4tec crankshaft coupler thread

    Can anyone tell me the size and pitch of the thread on the pto end of crank where the spline coupler threads on.
    I measured it and I think it is m27x2.5 but can anyone confirm for sure
    Thanks in advance

    Did you ever get this figured out? I’m building a mini jetboat and I have a 4 tech and would like to get a Yamaha pump hooked up to my 4 tec motor.

    Yes got it sorted . Look in that link info should be there. If I remember correctly the seadoo crank has a non standard m27x2.5 thread
