hi guys i juts bougth a 2007 grizzly 660 i took it for a ride and some times in the river when the water was too deep the atv seemed to go very slow like if it was going to go off and stay that way during the whole river butt as soon as i got out of the river it worked perfectly and that happended every time i went nto deep water.

the guys in the store here in mexico say its a mode that the new grizzlys have to auto protect themselves but i prefered to ask..

any coments??

ps..sorry of you dont understand me my english is not that good

 

any help plase !

 

Try a search on here about this. I remember reading a couple threads about the grizzly and entering water at too hihg of speeds and how it bogs down. Something to do with the engine being hot and when the water hits the motor. Try entering the water at lower speeds.
I'm assuming it does this in small rivers or creeks (up past floor boards) but not puddles.

How deep are we talking? Don't forget if you up over the tires completely it makes it harder for the tires to turn, that could be another thing you are experiencing, perhaps alone or in combination with entering the water at too high of speed.
Are you in low gear or high gear when crossing the rivers?

 

when the engine is hot and you hit water it creates steam. the steam gets sucked into the pannels into the intake. Try taking the panels off or cuting a bunch of holes in the \m to allow the steam to escape.

 

well i know you don't want to cut holes in your baby but this will help. now for some reason taken your ball barings out from under your gas cap helps a lot! don't ask me y but someone told me to do it cause i have/had same problem you are haven. i did it and boy there was a deffinet difference! try it before you cut anything let me know if it worked for you as well!
later
