we had an accident that our one week old 96 Polaris Trail Touring went into a pressure crack full of water. Fishermen nearby pull us out quickly but whole sled was in water.

I manged to drain and crank water out from exhaust pipe, air box,cylinder/engine block etc. After more than 200+ pull.........the engine got starting and I ran it for over an hour so its dry now. Thank goodness the air temp that day was just above Zero.

Problem that needs advice:
the engine can be started and idle every time. It runs well like normally BUT as soon as I press for gas to high RPM, the engine stop. Please advise!!! what to do.

Things that I haven't done yet are:

drain gas tank to replace with new.
drain oil to replace with new.
drain crank oil to replace with new. It there a drain plug for this model?
replace fuel filter.I took the carbs out today and blow dry them.

Many many thanks in advance!!!!

Wow, that sucks man! Sorry to hear it went under water. I don't know a ton about sleds yet, but I have had 2 different dirtbikes under water. It sucks. One of them I had to replace the head gasket because it poped it out the side. Anyway, you want to get every last bit of water out of there that you can. Clean out the airbox, carbs, and all oils completly as you can. water and oil mixed is just asking for trouble. I would make sure the plugs are still good too. I can't think of too much else off the top of my head. good luck!

As long as it was fresh, not brackish or saltwater, count yourself lucky. In any case, you'll have water in places that needs to be removed. It's very possible that little water got into your oil, but I'd still drain and replace it. At the very least, run mixed gas for awhile until you know there is no water in the oiling system. The crankcase needs no attention if you've run the engine quite awhile. However, I would pull, inspect, and clean the carbs to make sure they are not blocked or have water issues. Water from a natural source might easily introduce debris into the system.) If you don't completely drain the tank, at least siphon out all the pooled water and sediments you can see on the tank bottom. (Complete draining would be best.) I would replace both the fuel and the oil filters also. Shooting oil like WD-40 into the choke and throttle cables to help displace moisture might be wise as well. And after everything is all cleaned up I 'd run a bottle of Iso-Heet in a full tank of gas to make sure that moisture is moved along.

The seat will dry lots easier by removing the staples holding the cover to the base. You can press a lot of water from the foam, but it will take some time to dry. Trying to use it wet (frozen) will only be hard on it as the frost in the foam will case cracking a tearing.

I had a similar incident about 10 years ago, and managed to get the snowmobile running again. The advice given is good advice, I would agree with the above.
I had issues with the seat being wet-I took the seat off and dried it out completely. In addition, the gauges (tach, speedometer) were fogging up, and it took all summer to dry these out.
As is previously stated, you may have issues with water in the carbs. I had similar issues with snow dust, and you may want to take the carbs off completely, and dry them out.
Best of luck.

This is a great forum and I really benefit from your knowledge. Hope one day when I have more experience to play back.

I have taken both carbs, choke + cable etc to dry, clean and oil. Will drain fuel and oil out as well. Wonder if I need to check the fuel plumb too? as I mentioned before when press throttle for high rpm the engine stop... Would it be lag of fuel? Anyway I am take it step by step.

ouch man, i had a close call last week on a river.
i would take it off and make sure its dry and maybe take apart to be inspected to be on the safe side.also regrease very nipple. and check that your clutches aren't stiking after wards and make sure your belt is dry.

today I put the carbs back to sled and cheered with the roaring engine noise. Finally got the throttle to high rpm and the track is turning as it should be. Again.......a big thanks to those who gave me reply.
