I have had an intermitent problem with my 2000 Kodiak loosing power when splashed but I cound not reproduce the effect using the garden hose. I removed the regulator/rectifier and filled the contacts with dielectric grease. With all the mud and wet at Twin Hollows no problems occurred. Maybe this fixed it.

David another possiblity is the spark plug boot. I had a similar problem on my Grizzly and a little dielectric grease in the spark plug boot fixed it.

I had already tried that with no change in the problem. Thanks

David,
We had a problem with our 2000 Kodiak getting water in the belt; I don't know if it's the same thing you are experiencing or not. When I would ride through fairly deep water, I wouldn't have power... what it turned out to be was a loose clamp. I can point out exactly where this is, but I can't describe it in "mechanic" terms! ;D There is a plastic pipe that comes into the engine in the front, and the metal engine part is short. If you take a 4" rubber boot (?), slide it over both sides and clamp both places that should fix it. Once we did this, I've never had that problem again.
Good luck!
Debbie

Deb, I had that hose loose at one time and had to repair it. The motor flange is too short to get a good grip on. What I have had does not allow the engine rpms to increase for 30 to 45 sec and act like the sparkplug is shorted or water vapor is choking ignition.

Could it be water in you switch ? wd40 on connections might help you find loose or wet connections that are shorting .

it may sound crazy but have you checked your battery cables? I know the Grizzlies will sputter around if the connection isn't good.

The battery cables are a good suggestion and I have checked them.

ok, I am out of ideas. Sounds like the "trade soon light is on"
Drew told me that phrase once and I love it!

You sure you weren't getting water in the air box? And it seems to be sometimes when I hit really deep water on my 300 the very quick change in engine temp seems to cut the power down until it stabilizes, not sure why, but I notice a power drop when I first go into really deep water sometimes, but it usually comes back in a minute.

The airbox has stayed dry the whole time.

iI believe you are dealing with a steam issue , either Electrical or Fuel it is probably due to steam . When you hit that cold water it also does what Chad is taling about by cooling the engine so much that needs to change fuel mixture , and it is to lean so it looses power , but water vapor in the air can cause the same effect like when you are riding in the rain , but not in deep water . when it quits it will be a lot easier to find .

Drew. If it is steam ,why doesn t it do it all the time when the engine is hot? Do you think making the mix a little richer would stop this? At the moment it is a mute point I guess since it has not recurred.

When you spray you Engine with water , you get a burst of steam , but when you have rode 20 miles dry , then hit water and emerse the whole engine , you get steam for several minuites , that would be enough to block air and soak most of the electrial with water and steam after the water has long gone . I do get a big lose of power after and during being in water , but not like it is going to cut off , more so like it is cold and needs the choke , that I what I belive that is what is happening ( correct me if I am wrong ) . If you bike is shutting off , your idle could be to low to recover when it get cold ( your choke cable ups the Idle when pulled ) . Hopfully you got it , be glad to ride with you sometime , that way it you do break down you have a way back .

So far it has never shut off when this power loss happened. It just goes away in 30 to 45 sec by pumping the throttle.

After two trips to Hilltop I have had no recurrence of the problem. Sealing the rectifier and filling the connection with dielectric grease has done the trick.

David consider this.
When you run through water it will burn off and produce steam. The steam rises and will trap under the gas tank plastic where it is vacuumed into the air box inlet. This steam will not puddle in the bottom of the air box but will make the engine sputter for a short while until the moisture in the air being sucked into the engine clears up and or the engine stops producing steam. Some ATV's have more of a problem with this due to design, one of the early Griz's were the worse. Most have a foam piece that goes around the intake horn that is fitted to the plastic to block most of the rising steam.
When testing I bet you're not increasing the throttle while applying the water. At idle you have minimal vacuum in the intake, maybe not enough to draw in enough moisture to show up at idle.
I have no idea if this is the problem but it has plagued other ATVs. It seems that you may have it fixed but if it shows back up, maybe this will help.
