2005 Yamaha Kodiak 450 Under Water

Recommended Posts

its an 05 kodiak 450. i was going across a pond, i started off going across it just buy the bank, and slowly got to the point where it was inches under the headlights. i said what the heck i can go a little farther. as soon as i got to the middle, it dropped about 6 inches and the front went under, so i wheelied it. right rear wheel lost traction and it headed for the middle. i tried to get it in reverse and back it out but it was one of those times where it wouldn't just go in R. the whole quad leveled out, and intake went under. i pinned it until it sucked water in (heard this was the best thing to do so it dosent suck water back in on last stroke) and it finally died. i got off of it and let the rear float up so the intake was out of water, it turned over for about 5 seconds and finally started. i revved it for a little getting some of the water out and i finally reached over put it in 4wd lock and backed it out. pinned the gas and the belt was slipping cause of water in it. so i got in front of it and pushed the gas while pushing it out.i got it out and kept it running and drained the CVT and revved it hoping all the grit in the water ( not much) would drain out with the water. i kept that draining and took the tube off the front pipe vent for the CVT. and then the plug for the air box. i did all this while i was slightly revving it just to keep it alive and keep the tiny bit of sediment in the water while draining. i did all this in about a minute, DEFINATELY not more than 2. so VERY QUICKLY.

should i be good to go for riding more?

did i get lucky?

a couple more details.

the water drained out of the cvt for about 45 sec. to a minute.

the last bit of water that came out was pretty much almost clear.

couple questions.

did i do anything wrong after it going under?

could water have got in the differential vents also? i routed them a little higher than they were from the factory.

I would drain and check the oil. Keep changing it until it is not milky.

If it was me, and believe me I have been there. I would have cut the ignition as soon as you went under and then floated it to shore. Once at shore I would have pulled the plug and tipped it on its rear. Once the water is drained out of the exhaust I would have tipped it back down and tried to start it without replacing the plug. This will push the water on top of your cylinder and keep it from hydrolocking. The I would have took it home and changed the oil and filter a few times.

I think you did everything fine with the CVT you should be fine there as long as the water was not too dirty.

If you did not already bend anything you should be fine with a few oil changes as long as the water was clean. If not a ring job is in your future but nothing to worry about until you start getting power loss.

I think you did everything right and also got lucky. Give it a good washing and change the oil. Check/replace the air filter.

I used to get my 05 Kodiak when I had it, pretty deep in water..

you need to check oil for water. check both diff for water also. you should have pulled spark plug before turning engine over. if water got in the cyl you could have bent a connecting rod. if oil is milky do not run engine. water in oil = no oil pressure. you are pumping water thru engine not oil. water is heavier than oil so it is at the very bottom of engine. drain oil and change filter till oil is not milky. you might have to clean clutch and re grease.

I have to agree with everything Swampcat said, the last thing you want to do is pin the throttle when the intake is under water. You suck water into the cylinder and things can get real ugly. Water does not like to compress, you can break a crankshaft, rod or piston if you hydro-lock a motor and the faster it is spinning, the worse damage you will. The best thing to do when you submerge your quad is to kill the motor as quickly as you can. You definately want to change the oil and check all of the other lubricants for water contamination. Here is a picture of the kind of destruction that can occur when an engine tries to compress a cylinder full of water.

That was a disaster, just replaced the whole motor, wasn't worth trying to fix, the crank bearing seats weren't even round anymore.

      I have a 2005 Yamaha Kodiak 400 Automatic. It has an oil leak inside clutch cover. The middle gear has two oil seals, the front seal is leaking engine oil into clutch area. How do you change the leaking seal?

      Got my Yamaha Grizzly buttoned up finally and went for a quick 2 hour ride in the power lines with my neighbor, who has a Yamaha Kodiak. We have access from his yard, which is nice. Was a beautiful day today to get out and will try to go more often. Ran into two other quad riders with a sportsman and I think grizzly. Also ran into a dirt bike rider. 😎

      The VIN on my 2018 Kodiak 450 is not where it's supposed to be. I bought this used. Is there another "hidden" location where I can find it? Need the number for insurance co. Thanks in advance.

      I know this tooic has been addressed by many, I’ve looked through many forums and pages. I did not find anything like the problem i have.
      I have a 2007 Kingquad 450. I have a new fully charged battery. When i turn the key, the dash flashes and seems to struggle before getting fully lite. We can hear a small relay near the computer clicking, i think it is the fuel pump relay. When i turn off the engine kill switch and press the starting button relays click and all the power shuts off, i turn the key off, engine kill switch then start over, power is there. Atv will start with pull start, but not elextricly. if i try to use my winch, all power cuts and engine dies. 
      Can anyone tell me what it may be? or has anyone fsced an issue like this before?

      I have a 2018 Kodiak 450 EPS that just this past Sunday I ran through a bit of water.
      After the puddle the belt was slipping, so I pulled over and drained the ultramatic housing and the slipping problem went away. This was all in L and everything seemed to work fine. Later when I got on a road, I put it in H, but it still rode like it was in low... i.e. I had to rev it up a lot just to get to 30mph.
      When at home I pulled the ultramatic cover off to inspect, and it looked okay in there. Not much dirt, belt and everything are clean, but when I rev up the engine (with cage in place, of course), the belt doesn't get to the top of the clutch (maxes out about an inch or 1.5" from top of clutch, so maybe it is normal).. I put it back together but same thing... H seems like L still.
      Do you think the clutch needs to be further dissected for cleaning, or could this be an issue with the gear selector?

      I have a 2018 450 and the digital gause has started flashing on an off while driving. The backlit also goes on and off. It is worse when I hit the gas. The battery died a few weeks ago and I jumped it but its been fine until last night. Called the dealer and showed them a vid and they recommend replacing the gauge and its like 600 bucks. The machine has less than 100 hours on it. I would really hate to have to change it out. also the unit sometimes has trouble starting. Any ideas?
