Hey all, i need some help
2007 Polaris sportsman 700 EFI
so i was crossing a river and got caught in the current rolled the quad and we floated down 50 or so feet before i got it back over and we dragged it out (the bike was completly submerged). Drained the water out of the exhaust, airbox, belt cover ect., took out the plugs and tried turning it over. it was having a hard time turning it over but after a few rotations we put the plugs back in and tried to start it again with no luck. so we were close to the trucks and just towed it to them to work on it at the shop. Tried turning it over again at the trucks and it sounded like it was just clicking at the starter now without turning over, tried jumping it with no luck too. I just got back and havent taken a good look at it yet other then checking the codes and there were no codes present, checked the oil and there was no cream in it but it was about an inch past the full mark. Any idea on whats wrong with it?

 

Take the plugs out, drain and replace the oil (use a cheap oil but the correct grade),double check there is no sitting water any where else (like the airbox) and see if it turns over, if so let it crank for about two minutes (still no plugs in it and it should turn easy as no compression). Drain the oil and replace with more fresh oil but still the cheap stuff. At this point you should drain the gas tank and make sure there is no water in there. Then you should check where the stator is and open that up and check for water/moisture. Unless completely dry blow out with compressed air, not too close though. If it still looks moist hit it with a hair dryer to dry it out.

Once you are sure the stator is dry close it back up, add fresh gas and install the plugs and see if it fires up. If it does only run it for a minute or two and not under load. Drain the oil again, see if it is milky, if yes repeat, if no change the oil filter and add new fresh oil but I would still again use cheap stuff. Start it again, run it around for 5 minutes, no heavy load, change the oil one more time with the good stuff.

Then I would change all the fluids, front & rear diffs, gear box and probably also the coolant. The point is you want not to remove any water but any other contaminant mainly dirt which will wreak havoc on seals throughout the machine. Also give it a goon grease job and make sure you get all the zerts.

After that check as best you can all the electrical connectors, blow them out with compressed air as well. Good luck!

 

well thats gonna be my plan for tommorow. Any idea why the oil is so high now though? water probably went in the overflow through the airbox but the oil is not creamy at all.

 

It is high because of water in the oil pan. Water & oil together don't make it creamy colored....only when it is agitated together like when the engine runs. Once you drain it out you will see the water under the oil (water is heavier than oil ans gas so oil will float on top).
