Just wondering why and if i can fix why my 04 rubicon drowns out when water gets up almost over the seat. does it have something to do with the fuel acting differently in the carb when its submerged? i know the carb has vent lines running up the handle bars and i have an air tight airbox snorkel. It never has hurt it all i do is get winched out, park it on an incline with the e-brake on, choke it and start it until it cranks and when it finally cranks it has to sit and idle for bout 15 minutes before it runs right. I change the oil everytime this happened and never found any water in the oil. just wondering if theres a way to get it to retain its power under water instead of slowly dying then going dead. Any info is appreciated. Thanks!! oh and i will have some pictures uploaded soon!!!!

might sound dumb but you might have a cracked plug. had a friend with a foreman and had the same problem. found the whole problem was the plug had a crack you could never see with the human eye. Put a 2 dollar plug in it went right back to the lake and ran perfect. haven't had a problem since that was over a years ago

thanx for the info i wouldn't think it would be the plug because i have a couple of buddies in which we all went and bought rubicons in 04 within the same month and all 3 of em do it when the seat gets close to being under water. I'll plug that line and see if it does any different. It'll be awhile before i can test it for results. thank you.

Also,remove the spark plug boot and put some di-electric grease in the boot before re-installing it.

i agree with the geasing the spark plug, i used to have a rubicon and when i would ride deep it would stall because of the spark plug. after that i could go as deep as i wanted to.

my 2 carb vent tubes are routed up to the handlebars and come out beside the electric shift buttons on the left handlebar. maybe my buddy in which i bought it from done that. he didn't tell me if he did haha. i know i never moved my vent lines on my yellow rubicon i had and that may been what was causing it to go dead when it got deep. i am definitely gona grease the plug though. i have had my red rubicon only since last friday 12-21-07. i haven't had a chance to see if it will die yet, thats why i went and got the exhaust snorkeled in case it did go dead when i get a chance to try it. thanks

found out my carb vent lines have been extended to reach all the way up to the handlebars. there is connectors in the lines that have longer lines hooked to them. the guy i got it from done it and i didn't know about it. i really have based this thread on the yellow one i used to have and why it would drown so easily. the guy i got the red one from (one i presently own) used to go riding with us and his never drowned out and he never told us that he had that done. Sorry. until i talked to him about it, i thought the vent lines were just ran like that - although it didn't seem like something the factory would do anyways. Thank you all for your advice and input. -- ---SNORKELS UP FELLAS!!!!--- --
