    water in exhaust question

    hi all. newbie here. just purchased a 09 SHO with 55 hrs. I am doing the manifold mod and tommy j exhaust mod. When I took of the exhaust hose, water leaked out and my resonators are full of water, both big and small one. Is this normal? Im kinda new to the jet ski cooling system.. Also, after the manifold mod and free exhaust mod, will I be hitting the rev limiter?Thanks

    yes, water gets blown into them when the ski is running, thats how the exhaust system is cooled

    Water flows through the exhaust and you will probably be on the limiter..

    ok thanks. sorry for the stupidity. One more question. When I did the exhaust, I noticed there is a little black hose that is just hanging from the top of the hull. its not the bilge one. theres a little white vent cap coming out the top on the rt rear. Its the black hose that hangs down from that. its about 2 ft long and has a clamp on the end , so it must connect to something. please help

    That hose is initially connected to the stock battery from the factory. If it's not connected to anything then you probably have a sealed battery or something.
