Not familiar with seadoo's, but there is nothing like that on yours. Just the water supply to the engine, and the bilge pump discharge tubes. If you wanted you could pull the pump and check the supply port and impeller clearance. Need to make sure the gaskets are installed correctly. Did you check the cooling passages in the head ?

I blew compressed air through the water jackets on both the EM and head. During the first tear down that did not include removing the Head Cover I may have installed the gaskets wrong because I read in the shop manual there is a stamp stating UP. I’ll check this time for the stamp..

Out of curiosity, how did sand find it’s way to the area behind the stator motor cover?

Could sand enter the oil pump?

1997 Kawi 1100 STX Oil Pump

Quick question for a serious matter.

My husbands dad was working on his Jet Ski to resolve an over heating problem so my hubby and I could use it next week before he ships off to Iraq for another tour. Both of them had to help a friend whose house burned down last week so they are unavailable to help me.

My neighbor tried to help me this afternoon and removed the oil pump from the Kawi trying to help me solve the overheating problem, but he only removes parts and does not know how to put them back together.

I am an Arizona gal so know my way around tools and after evaluating the problem it looked simple until I noticed the pump would not align onto the stator cover plate so I could attach it.

It is dark now but I did notice there is a small 1" metal rod on the oil pump that turns and I am presuming it needs to be aligned into the gap in the flywheel?

To ensure I got this right, can I presume if the oil pump meets the stator cover and bolts down with no space between the cover and the shaft, that the rod did in fact slide into the Flywheel?

Come on guys, give the blonde babe a hand...Thank you.

1997 Kawi 1100 STX Exhaust Pipe Gaskets

I was cleaning my Kawi to resolve an overheating issue and now that I am reassembling the exhaust pipe to the exhaust manifold I noticed the Service Manual instructs to ensure the two gaskets are installed correctly. Unfortunately there is no "UP| mark as stated in the service manual. There is, however, on one side a recession (swimming pool) going around the entire gasket and on the opposite side a bulge. I am presuming one of those indicators is the upside, but which one?

Anyone know?


Thanks

Sorry to hear about the friends house. That sucks.
You are correct. The drive tang on the pump inserts into the slot on the drive adapter in the stator cover.
What specific gaskets are you talking about ? A picture of them would help. Also, the head gasket also has a arrow on it that needs to be pointing to the front of the engine along with the "up" being oriented correctly.
Because there is no filter in the water supply line from the factory, sand can get sucked up through the jet pump. You can get inline sand filters, but it needs to be high quality. No, sand cannot get in the oil pump unless it is intentionally added to the oil tank or supply line.

Was there sand in the stator area or just behind the small cooling cover ?
Again, make sure the fitting and passage on the jet pump is clean, make sure the supply line in not soft or kinked. I'm assuming that you check to make sure the inlet fitting on the bottom of the exhaust manifold was clean ? Has anyone actually touched the engine after it was run on the water to see if it was actually hot, or are we just going off the over heat light on the dash ? Since sand was found all through the system, I highly recommend taking the temp sensor apart and cleaning all the corrosion and sand from it. It's a bugger, and it has to be done carefully because you will not be able to completely remove it from the ski. I put a piece of 2x8 or 2x12 across the engine compartment opening as a make shift bench to work on so the hull does not get damaged.

The sand was found behind the front cover that mounts to the Stator Motor. (The oil pump mounts to the cover) Not a lot if sand, maybe 15 per-cent of the entire area, but is was caked on the back of the cover, easy to clean. There was no sand in either of the two brass elbows that attach to the cover.

If you have everything clear, and all gaskets are installed correctly, you should be good. Back it into the water, fire it off and let it idle for a bit on the trailer while feeling the head. If it stays cool you should be good. If it gets to hot to touch, it's getting hot. If it stays cool to warm to the touch but the light goes off, the sensor is prob restricted. Under throttle the pisser should have a good hard stream of water coming from it, and it should just be warm under normal riding.
