    One or the other but not both. I usually do it with the exhaust on. Then I install the carbs in boat.

    Another tip on the U-pipe assembly. Get all the cable connections, hoses, etc done prior to installing this mutha. Then put the bolts in it prior to installing you will never get them in once it is in the boat.

    ditto on what Bill said. I always install mien with the EX. Man. on too.

    Also, when installing the U-pipe, it goes on easy. It can look intimidating, but with it laying flat, picture it as a boomerang. sitting on the seat, looking donw on the U-pipe, it will spin counterclockwise in place to the mouth of the exhaust manifold. Even if the PV bracket is in place, thats fine. It will spin around it. It falls right in place everytime for me. Also don't forget to hook up the water lines to the U-pipe.

    hope I explained that o.k..... ......


    another tip, those two exhaust manifold bolts on the top of #2 cylinder that are nuts. I use red loctite where it goes into the cylinder and blue on the stud where the 2 nuts go. that way, when you try to remove the EX manifold later down the road for whatever reason, the nut will not back out the stud.

    Good point on the studs. Every ski I have had those studs would back out. When I installed them I did the same thing. I installed the studs with Red loctite and then put double nuts on them and used them to tigthen the stud to the cylinder. Never had an issue after that.

    This is one of the very few places I use loctite. I know this goes against the general consensus here, but I use antisieze on all the other exhaust bolts. All my bolts are thoroughly cleaned and all my bolt holes I clean out with a tap and wd-40. I apply antiseize then torque to spec. I have never had an issue and next time you tear down the ski everything is a breeze.

    I do that on a lot of certain things too... love it. I always keep a keen eye on things though.

    I am a big fan of anti seize on any thing hot or under water. Than various loc-tites purple for small screws blue for most every thing else red for the stuff you do not want to back out and green for the permanent stuff.
