660 engine fan removal??

Sorry if this is a stupid question but i am new to the whole Rhino thing. Just got myself an 07 camo 660 with too many options to list. Love the machine but noticed the first time I was in water about 3-5 inches over the floor it bogged out like it was loosing power. I thought a connection at first. So i checked it over found the plug boot was off just a bit. I figured I had the problem solved. Then went in some deep water this weekend and it boggs and sputters the same. So i started reading on snorkels and noticed something about the fan removal on the 660's? Any help is appreciated.

maybe a link to a thread for the removal and what the benefits are?

Thx alot

You just unbolt it- it's the fan that's attached to the passenger side of the engine. I took mine off to do the 686 kit, but haven't put it back on. I'm not a mudder, but I can't really see how effective this fan would be... just blowing air on the stator cover? I think I'll leave mine off... I know a lot of guys do. It's the only way you can run an alternator, so it seems common!

ok, its the dumbest thing yami did, its a fan runs of the crank to turn a fan to blow air on the stock exhaust rubber bracket, u can see a tube ran to it,

when u go in water or mud its fighting to turn ur motor thru the mud n water,

its a for sure thing to remove, and they didnt install it any longer on the 700 models anyways

remove passenger seat, remove the black cover from side of motor and 4 bolts bolting on fan and the washer plate, remove all that crap install black cover back on and ur done,

I have the same issue as well and was wondering why this happens... I live here in Flori duh and when in the muddy water it bogs as if it is going to conk out.... It never does but sure freaks you out thinking it might stall... I am all snorkeled out and even have the gas tank vent removed from the frame and lifted up to the level of the snorkels... Think removing this fan will help my issue?

It for sure will. Mine has been off over a year now. No issues.

Hey MB,

There's a new guy scutty83 thats looking for the stock fan assembly, you may be able to sell it for a couple of bucks.

Here's his thread:
Newby Owner needs Rhino 660 parts!

Thx man but I think I will keep it just in case I ever get rid of this thing. That way I can put it back on if the next guy wants it. I havent followed this thread but I read someone was worried about the stator is that acutally a concern?? I cant see this little fan cooling much of anything except that exhaust mount?

thx MB

are you shure its not the coil getting wet. I have a hard time believing that a 660 engine cant power a little fan in water. try spraying areas of the engine with water starting from the bottom up.

I've done some deep water crossings and never found that that little fan robbed enough engine power to notice a difference.
You said that it sputters. That fan wouldn't cause the engine to sputter.
If it's bogging/sputtering that much, I would suspect something else is up.
