    Re: 96 XP Engine Rebuild and Carb Rebuild problems

    You did hook the water lines back up to the cylinders right?

    The two black hoses going into head? Yes.

    Re: 96 XP Engine Rebuild and Carb Rebuild problems

    I turned the low sides out another 1/2 turn (1 1/2 altogether) and it's not hesitating like it was out of the water. We'll see how it does when it's in the water tomorrow.

    I think I found one of the places water is getting in...a couple of the rivets that hold the old black plastic foot mats are broken.

    No, the small tubing at the bottom of the cylinders, left side.

    Re: 96 XP Engine Rebuild and Carb Rebuild problems

    Oh, yes those are hooked up. I think I found why it is taking on water. After inspecting the carbon ring I noticed the driveshaft wasn't right and on further inspection, I found this in the box where I put the nuts and bolts. the plug that goes on the end of the drive shaft... DOH!IMG_3593.JPG

    That could possibly allow enough forward movement under power to unseat the carbon ring. But, only if the bellows is worn out.

    Re: 96 XP Engine Rebuild and Carb Rebuild problems

    What's a bellow? I just got everything back together and I am gonna put it in the water and see if it fixed it or if it is still leaking. I also put a little more grease in the shaft.

    I have the lows 1 1/2 turns out now and the highs just cracked open and it is still hesitating a little bit when I mash on the gas. Let me see what happens in the water.

    Re: 96 XP Engine Rebuild and Carb Rebuild problems

    The bellows is the black accordian boot the driveshaft comes through. Warm it up good before making any adjustments. You can back out the lows a bit more if necessary but I've never had to back any out further than 1 3/4 on a stock boat. Make sure complete flame arrestor assembly is installed. If its open it will run lean.

    Re: 96 XP Engine Rebuild and Carb Rebuild problems

    Well, I just took it to the boat ramp and tied the front and rear end down with straps to the trailer, backed it into the water while still on the trailer, and started it up to see if the water was leaking in which I didn't notice any.

    Here is what is going on with it now...it runs out of the water and I can get it past 1/3 throttle. Once I back it down into the water it will run but I can't get it past 1/3 throttle and then it will die.

    Also, it isn't a stock motor anymore. I had SES rebuild it to their high-performance package so I wanted to share that in case it makes any difference on any adjustments.

    Does the idle adjustment have anything to do with any of the issues I am having do you think? Like I say it runs descent out of the water.

    Re: 96 XP Engine Rebuild and Carb Rebuild problems

    Sounds like a fuel issue. Does it do this in the reserve position also? Have you tried pulling the choke a bit while revving? Does it die out or rev up more?
