Hey guys, went out for a short run today on the 96XP, and everything seemed to be working well. Only went out for a short time, maybe 40 minutes, since water was ice cold. Unfortunately I didn't think to look back at the tell tale pee hole while I was on the water. Came home, decided to run it on the hose to flush the cooling system. Hooked up hose to the quick connect fitting, and pinched line behind the fitting per manual. However, while running there was no water at all coming out from the back pee hole tell tale. Usually while flushing I have a nice stream back there. Water was coming out of exhaust and jet pump, but none from the tell tale. As soon as I realized this, I touched the engine to make sure it was cool and that water was getting through. The PTO side was cool to the touch, but the mag side was quite hot, almost too hot to touch but not quite. Exhaust manifold and pipe were cool. Ran for a few minutes and still nothing out the tell tale. Took hose off head pipe where water exits for tell tale and there was a very slow stream coming out of there. However, since there was absolutely none coming out the back, that might lead me to believe the tell tale hose may be blocked? But if that's the case, why is one side of my engine running hot while the other side is ice cold?

No Water From Tell Tale Hole When Flushing?

If you follow the hose from the exit toward the engine, you will come to an elbow. That elbow gets plugged all the time. Also, and I don't know right where it is, there is a drain on the engine. If this drain does not work, then there is sand and debris in the water cooling jacket.

I would pull the hose from the front of the head to the head pipe. If that is restricted it might cut down the flow enough. You can also thread that fitting out of the exhaust mani and check to see if it's clear. I would also remove the black hose from the fitting on the EM and use compressed air to blow towards the pisser line. I've seen what looks like pollen clog those hoses. Probably a good idea to blow thru the exhaust fitting that is for the cylinder drain.
The link is for the rear exhaust fitting for the cylinder drain.

Let me know if you find anything.

As noted above, simply follow where it exits the ski toward the engine, you will run right into it.
Thanks. Found it, checked it and it was clear.
Did you pull the hose off the head to pipe? The 6-7" piece right out the front of the head. If the connection on the head side has a little muffin top to is that is suspect for corrosion. Again, a mirror and a flashlight will help you see back into that port.
I know on my 96 I get a nice sharp stream on the hose,and I don't even pinch the hose going out the back of the flush fitting.

Yeah, something's not right. Is it possible the head passages could be clogged? I'm concerned that the mag side of the engine is getting so hot while the other stays cool.
The outlet port, the one I asked you to check can plug with corrosion. I'd say it' probably more prone in salt water areas but I have seen some freshwater heads get nasty too. The aluminum is just raw so water alone will promote oxidation. When enough oxidation collects it can plug. I'm looking for a pic that I have to show you what it looks like.
Hey guys, quick update. Went to work on it today and see if my line from the manifold to pee hole was clogged. This appears to maybe be the case, since I have a decent stream coming out the manifold when I remove that hose. But when I put the hose back on, nothing is exiting out the back.
But, that still doesn't explain why the mag side cylinder was running hot while the pto side was running cold. So I decided to pull the PTO side spark plug when idling, and to my surprise it continued on idling with no change. Put the plug back on, pulled the mag side, and she died instantly. This tells me the engine is idling on only the mag cylinder, which explains why it's running so much hotter. The thing that baffles me is that it ran perfectly on the lake Saturday. Checked compression, 150 PSI on both cylinders. Changed spark plugs and trimmed back plug boot, no change.
Now I am really stumped. Anyone have any ideas?

Well for starters. Replace the spark plugs, the pto plug could be fouled. Next, pull both of the spark plug wires out of the boots, cut about 1/4" of wire off so you got some better, fresh connection, and push that back in the boot and twist a little bit at the same time. Also, when you put the boot on the plug, you should hear it kind of "click" when it is fully seated
Thanks for the tips. Unfortunately I already did all of those things, to no avail.

I had the same thing. I had water in my box. when I would hit a wave it would cut out. If you want you can get a spark checker at HF paid like $5 or it or you can just ground the plug and hit start.

if you buy that spark checker, you could check the cylinder at idle and then ride it with the seat off to see if its getting spark.
Update: did an experiment today to see if spark was causing the issue. I switched the spark plug boots to see if that would make any difference. Unfortunately the same thing happened, with it only idling on the mag side cylinder. So this seems to eliminate spark as a possible issue. I would have to think this is a carb issue?
Update: problem solved. Turns out there was nothing wrong with the ski at all. I decided to try hooking up my flush hose directly to the head instead of using the flush fitting, and low and behold, I had a geyser coming out back! So, the stock flush fitting, which is brand new, was restricting the water flow from the hose. Not sure why that is but oh well.
As for the one cylinder not idling, made a quick change to the idle screw and now both cylinders idle fine. Back to the water!
