    problem with 99 XLL

    Ok, I was doing some speed runs trying to see where I was at, hit 65.3 with the rpms @ 7330... It bogged and died, started and died... Pulled the seat and there was the culprit, exaust bracket that holds the rubber boot onto the stinger was off and water was leaking into the hull, not a ton but I was in a slight turn headed into a cove... I am guessing I sucked some water in the carbs... Made it back kinda partial throttle still was bogging, just checked compression, 120 across the board (thank goodness) what do I need to do from here?
    Thanks in advance
    Chris

    Hello Chris are you talking about the big rubber boot on top next to the head. If yes you are building a lot of water pressure and causing the boot to slip out, That is also common with people using the turbo tube. One way to cure it is put Ts on the hoses look at my wife's build and you will see how i did it. Do not start the ski without putting oil down the spark plug holes first because when that hose pops off water goes to carbs. right away and you will seize a engine right up or score a cylinder.

    Thanks Jim for the quick response, so I want to T off the hose on the #2 and #3 cyl from the head and install 2 pissers to relieve the pressure? Also on the oil, I was thinking a tablespoon of 2 stroke oil down each spark plug opening, sound ok?

    If you have the stock head T off the 2 hoses coming out of the head and put 2 through hull fittings, If you have the 3 piece heads just run the number 3 straight out to a through hull fitting.
    On the oil i would put 1 ounce down each spark plug opening make sure the piston is down when you put the oil.
    If you do not want the through hull fittings showing you can put them next to the stock ones.

    Where do you get the through hull fittings?

    the actual numbers will vary from gauge to gauge, this is just a cheap one, I just wanted top make sure they were even... Its milled for 140, if I get rid of the center layer on the head gasket it would 150, not looking for that yet...
