    It's a pain in the ass. You will need two people and remove the SC to get to the locking nut that holds the shaft in. I use a large crescent wrench and a breaker bar to break the nut loose while someone holds the impeller steady with the 12mm allen and an extension turning the opposite way. It is the easiest with two people. Once the nut is loose, the person in the rear of the ski on the impeller can do the rest of the work. The shaft will come out once it is backed all the way off. Good luck!

    Yes. It needs to come out for added room to work. Just easier with it out.

    The front part sounds right. But my 09 pump has a different pump shaft set up. No 12mm allen will work. Its has a big nut, size unknown and the shaft has flat spots to put it in a vice to take the prop loose. I hope the front part comes loose first for you, because the front shaft nut, the prop, and the nut on the pump shaft are all torqued to 92 ft/lbs.

    It's like a 1.25" or something huge.

    What you can do is still use a crescent and a towel in the top or side of the tunnel and possibly on the plate on the flat part of the shaft or get the proper socket. The crescent would allow you to break the front bolt loose without un torquing the rest of the system. I used the socket set from the neighbor who does diesel work for a living.

    I misspoke on the rear part doc! That's my fault. Thinking too quickly.

    When josh, Murray and I ran into this at MB last year, we ended up removing the grate and using a pipe wrench on the shaft due to stripped splines. It was a pain but we got it.

    so is the nut near the carbon seal a locking nut or does it need to torqued back up to spec when putting shaft back in?
