    kawasaki 1997 stx 1100 tubing and hose question

    i pulled the motor and fuel tank out of my ski a couple of weeks ago because of a water and oil leak. repaired the leak and replaced the hoses and bilge pump filters and forgot where some of the hoses go. the two hoses from the very back of the hull, one is located above the jet pump and one on the lower part of the hull that goes to the exhaust pipe and manifold. one has a brass tee with a big nipple, the other side, a small nipple. on the top of the exhaust there is a single smaller nipple for a hose to connect. i also have the hose that comes out of the oil tank that connects to the oil injection at the front of the motor but not sure which nipple it connects to, i have two nipple that are not connected on the oil injection. are there any pictures of where the hoses for water, oil, and fuel tubing is routed on a 1997 stx 1100. any help is greatly appreciated.

    I looked at my '98 STX 1100. The exhaust system parts are the same on the '97.

    The oil lines are simple; the big nipple is for the 1/4" supply hose, the smaller nipples are for the 1/8" hoses that go to the carbs. It doesn't matter which carb hose goes where on this engine.

    The small nipple on the front of the exhaust pipe is also a simple one. It goes to the overheat sensor mounted to the fiberglass on the left side of the glove box. There is another hose from the sensor that goes to the pisser on the right side of the 'Ski.

    The large fitting on the exhaust pipe TEE has a S-shaped hose that goes to the cylinder head. The smaller fitting is plugged and is used for the flushing. Yours may have a garden hose adaptor.

    The hose that goes to the vertical fitting on the back of the 'Ski (above the pump) connects to the fitting on the bottom of the muffler.

    Here are some links:

    thanks steve

    I took a few days off, got tired of looking at it, I think I will take it by a shop, with my luck I have a couple of hoses in the wrong place. I learned a lesson, take a ictures before taking everything apart, appreciate all your help, thanks again, russell.
