I tryed to cross a creek in my new 300ex and made it over but not quite back. Half way thruough it stalled out. I pushed it to the bank and started it. It blew water out the exhaust for a while and the air filter box was full. Is there any thing i should do. Example: change oil or whatever ?????????? thanks

Yes You should change your oilif it is a milky color!!!!!!!!!u should do this a couple times to get the milkynes completely out of your 300s system

 

Of course it's too late to mention it now but you should never start an engine that has been flooded in deep water without draining it first. Water is a noncompressable liquid and for that reason can cause severe valve damage to an engine.

Once you drain out the water/oil mixture, remove the oil filter and replace the cover without installing a new one. This will keep water and moisture that is still trapped within the engine from quickly contaminating a new filter. Fill it with fresh oil and run the engine for a few minutes before repeating the process. It may take several oil changes to remove all the milky residue from the oil. You should also remove the drain screw from the carburator float bowl to make sure no water is left there as well. Replace the oil filter after the oil looks okay and check it again in a week or two.

And try not to fret about it. Two years ago I sunk my Bayou while trying to carry a 100 pound wild pig across a deep swamp. I had in running like new later that day and it hasn't missed a lick since.

 

I've submarined mine more than a few times, if you do much creek riding a well-oiled K&N filter is good to have since it keeps water out surprisingly well, so long as there is some of the filter above water it keeps going, but it is wise to keep RPMs low.

First thing you want to do before trying to start it is pull the spark plug out, flip her upside down and crank it over to get rid of all the water. If you have a foam filter squeeze the water out of that. Then back on its wheels you turn off the gas petcock, unscrew the carb drain and drain all the gas/water out of the carb bowl. The oil change isn't critical and can usually wait until you get back to base.

go to my site in galleries 11 and 12 you can see my 300ex stuck in deep water. it didn't sink cuz i pushed it out. you can see.

i agree. i change oil and checked air filter. i might go to the carb later when im not so lazy.
