    Drive Shaft Coupler Problems

    Im haveing trouble (again) getting a drive shaft coupler off of my slt750. Its stuck hard and refuses to budge. So, how would you recomend getting it off other than the string method? I tried it but its in there and I dont want to damage the piston or crank. Im yanking the motor out of the hull tomarrow to get at it better. Any help would be great. Thanks Rodney

    As long as you're using the piston nearest the coupler you shouldn't break anything. A sudden jarring snap usually works pretty good.
    Are you sure you're loosening in the correct direction?

    I'd suggest a large pipe wrench and leaving it in the ski.

    Once it's out of the ski, the engine will roll before it lets the coupler loose.

    standard thread turning it counter clockwise looking at the back of the motor. I have a new coupler for it and checked and rechecked about fourty times to make sure I was turning the right way. I even hammered on the wrench...nothing. Bigger wrench(pipe) and hammer and still nothing.

    Slip a piece of pipe over the handle of the pipe wrench as a cheater bar. Increasing length increases leverage.

    I used a two foot pipe wrench with a four foot cheater and my world didnt move sadly. even a two pound hammer for a "BFH" But I was holding back Im sure. Ill try it again tomarrow and not hold back if thats what you would recomend.

    Have you put some PB Blaster or other penetrant on there, and let it soak?
