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
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.
