    Default drive shaft brass key

    Yesterday I was out on the lake doing some surfing, turned to pick up my rider and there was a click and all of a sudden It was like the boat was in neutral.

    We had to be towed to the dock, I was super concerned that I had damaged the tranny or v drive. I put the boat up on my boat lift to find that the drive shaft had come out of the coupler?? I happened to have friend at the lake who is a mechanic and he came and had a look at it, he promptly took the coupler off and found my broken brass key stock and the stainless nut. He offered to put it back together for me but we didn't have brass key stock………
    I was able to make a call to guy at my lake who had some, and we put it back together and boat is working prefect. But I have never heard of the key stock failing at the top of the drive shaft before.

    Anyway I was super grateful to my buddy who helped me out of a jam !

    Now I need to replace the key stock, does not seem to be very common, any idea?

    Might want to keep a key like this with you. I think the key is the same for both ends of the shaft.

    I have just ordered this kit as well as a few "keys"
    I just thought it was weird that this would fail but not the one on the prop.

    It is weird but if your coupler came loose from the shaft who knows what can happen. Make sure you get the little set screw tightened down so the coupler nut doesn't come loose again.

    Here is a pretty good picture of how the set screw is designed to hold the nut in place so the coupler cannot come off the shaft unless the screw is first removed.




    Also, if you need a special (super short) socket for the nut or the separator tool you can get them from Elbert's:

    That picture is perfect, you can even see a bit of the small spot for the brass key!
    I was just super lucky I didn't have to tow my boat home and was able to have a friend fix it on the lift for me!
