Sounds like you have a clog somewhere in the cooling system. Take it apart and use a compressor to blow air through and see what happens. You should check the water regulator for any leaks while you are at it and don't forget to check all the boots too. Worst case senerio heck the compression in each cylinder. they should be around the same.
exhaust issues with 1998 seadoo xpl
my 2 stroke seadoo ran well for approx. 10 min. then started to smoke and bog down. upon investigation the rubber hose that was conecting manifold to rest of exhaust had blown out. I replaced this hose. same thing happened. any ideas on why and how to fix. thanks

If your a salt water rider and don't flush constantly it could be all crystalized in the coolant pipes you could try salt away flush stuff or I've seen some guys use a coat hanger in the passages to chip away at it just don't poke too hard
^ that could be another possibility too. NAd yes be very careful if you are going to attempt to clear the passage with anything make sure you dont puncture anything.
you have a problem in the water regulator, if you run it on the flush check your water regulator and see if there is water leaking out of it, there is a rubber diaphragm inside that rubs on a spring clamp and over time gets a hole in it, if it looses enough pressure in the system then the lower part of the exhaust overheats, if there isn't a leak from the water regulator then pull the top hose off the side of the regulator and you should see water come out of the regulator, if you do then try blowing into the hose and see if there is a restriction, that hose should go to the side of the tuned pipe...make sure that's where it goes, if you don't have water coming out of the nipple on the regulator make sure the lower hose has water coming out of it when you take it off the regulator, if it has water coming out of it then the problem is in the regulator...if there isn't any water coming out of the hose then the problem is before the hose, that hose is tee'd into the main cooling inlet line from the jet pump.my 2 stroke seadoo ran well for approx. 10 min. then started to smoke and bog down. upon investigation the rubber hose that was conecting manifold to rest of exhaust had blown out.
