if u did not kill the engine before it went under water I believe u need to take the engine apart to get rid of the water somebody should be able to tell me if this is right or not. if u killed the engine before it went under most people take the spark plugs out and pull the engine over until the water is out of the engine. There are many people on here that can help u out. when I watercross my number 1 rule is if u are going to sink KILL the engine before it goes under.

Here's how I'd do it, empty the gas out of your tank, empty oil tank pull over sled until all the water is out while on it's side(with plugs removed, pour some oil down the cylinders, fill oil tank, then fill your gas tank. Then try and start. With any luck your sled should be good to go, however I might consider premixing to get a little bit more oil in the crank.

Because sleds don't float. Maybe its different in Canada.

First things first. You want the sled OFF before you go under.

1. Biggest concern is getting the water out of the engine. Right side up, pull it over a bunch with the plugs out. Now, upside down, or on its side pull it over. Taking the pipe off will make it go faster and let everything work faster. Pull the carbs off and pull it over more. Clean your carbs with gas to ensure all the waters out. Drain your gas and oil tank. Your most likely going to have to replace your headlights. Put a little 2-stroke mineral oil in the cylinders and pull it over some. Carbs back on and a new set of plugs. Pull it till she fires. You want it running as fast as possible to prevent rust buildup on pistons, cylinders, and bearings.

So water doesn't get sucked in the air intake and into the cylinders.

Because water in the engine while its running may hydro lock the engine, which may bend/break rods, and do other damage to engines. If you hydro lock an engine your going to be tearing it down. If the machine is fully submerged, engine running or not your going to get water in from exhaust and intake. If I ever sunk my sled I would pull the engine apart regardless, you may get all the water out of the combustion chamber and it will run but your most likely not going to get it all out of the cross shaft that runs the oil and water pump. Just my .02.
