I purchased a 98 challenger @ end of season last year. i put it in water saturday. all worked perfectly until....i went to check it monday and it was Half Sunk!!! both motors were underwater. there was a leak in the stern somewhere. i got the thing out of the watter and bailed out but is there any chance of saving the motors?
thanks, ERIC
 
Yes!....

Yes there is........but time is important right now. If you got it on dry land right now, take out the plugs and try and roll the engine over. If the engines turn over, pour about 1 ounce of your 2 cycle oil in the plug holes to lubricate and displace the moisture.
If the engines dont' turn over, you need to remove the shaft guards on the back, then remove the plugs and turn the engines over by hand. Add the lubricant...
What you've got to do first and foremost is keep the engines from seizing up. Once the water was removed, the rusting process was set in place. These motors are designed to be sealed from the elements and even in a "flooded" scenerio the engines survive only when the proper steps are taken to protect them.
After you get the motors turning over and lubricated, then lubricate the outside engine parts.......carbs etc........spray liberally WD-40 all over them. If the engines won't turn over, check your fuses.
I wonder why your auto bilge pump didn't work properly?....Good luck!
 
Agree with the Skatman, get the water out as quick as possible, also once you get it running go for a long hot drive to get all the moisture out of the engine bay and engine. Maybe even run your bilge blower to get the moist air out. make sure you fog the motor and engine bay after, it may be worth your while to check counter ballance shaft oil galley to make sure no water got in there.
 
It isn't good practice to leave the jet boat in the water for any length of time. You should always either pull it out or put it on the trailer. It is possible that the water seeped in from the impeller shaft boot. Keep us posted on the results. If you gt in a jam give us a shout.

still got water

I can't seem to get all the water out. I am not too familiar with the way a rotax engine works but ive been crankin it with the plugs out. at first it blew a whole bunch out, but now its a constant white sludge mixture blowin out the plug holes. where is the water and how can i remove it? i sprayed it w/ wd40 and anti fog for the night but would like to try again tomorrow if there are any suggestions. one thing. the boat is not on land, it is strapped to my dock so the whole stern jet drives and hole in the hull are out of water but the bow is still afloat
 
you may need to remove intake and let water drain from rotory ports and then try to suck up what is left with paper towels or rags turn engine over by hand to expose both rotory ports. good luck as I can allways be wrong. Robin:)
 
Eric, the only way to get the water out of the engine is to keep cranking it over with the spark plugs out and the plug caps on the grounding posts. Clean the spark plugs after it is all out and apply choke and it should start. If it isn't starting remove the plugs and do the procedure again. On the 787 engines is a oil passage from the crankcase toward the balance shaft gear and bearing. Water that enters the engine can flow through the passage and be trapped in a cavity. Remove the plug on the counter balance shaft on the engine crankcase,( it is a round plug with a slot in it about 1/2 ", in diameter). To check if it is contaminated put a piece of wire and dip it in the oil. If it is white in color it needs to be changed, it has water in it. It only holds 1 oz of 30 wt. oil but it needs to be clean.

I'm not guessing...this is how to get it running and is also direct from the service manual!

If the exhausts are full of water you wont get it to start. Motor cant over come back pressure. In a regular pwc you would tip and roll the water out of it. I would yank the exhausts, drain them, slap them on and get those motors running. Running them and gettting them warm will help alot and be sure to oil the bejesus out of it till you get them back to life. I think the intake side will cure itself if you can get them to fire and run.

Good luck!

Another method to get the water out of the exhaust is on the trailer raise the front up till the rear touches the ground. With the nose pointed up in the air it will dump out the water enough to get it fired up. I wouldn't quite because if you do and it isn't tunning it will seize up from sitting.
 
ok I will trry that, what is a plug cap and what is a grounding post? ive been crankin them alot but the sludge just keeps coming? is there a way to shut the oil and fuel off while i crank to get the water out?
 
A "plug cap" is a "SPARK PLUG CAP". The grounding post is located near the cylindered that has a orange plastic holder with 2 post sticking up. You put the "Spark Plug Caps" on these to keep your ignition from overloading power and complete the electrical circuit to ground from the caps to the posts. If not you take the chance of causing more electrical problems. The fuel and oil won't really be effected from cranking it over as it needs the spark plugs to have compression to suck in fuel and oil. The 2 stroke doesn't have a fuel pump like cars do.

Time is ticking, its been 4 days now, you need to get this done as quick as you can, time is of the essence if you want ot save the motors.
the white sludge is fuel,oil and water mix, spray more wd40 inthere and get it as clean as you can and get those plugs in and fire it up, you need to get the heat in the motors now!! boil the rest of the moisture out, then check your oil gallies to make sure it's not contaminated.
Be careful not to crank it on the starter for to long or you could burn it out, i would recommend that you only crank it for about 10secs and then give it (the starter motor) a chance to cool down.
Spray, spray, spray and run, run, run.
 
i have been crankin it but the white sludge just keeps coming. like u said, i dont want to burn out the starters where is the water, in the crankcase right? there is no way this will fire with all this sludge. it would instantly coat the plugs
 
It should clean out as it is turned over. There is no real way to get the watr except leave the plugs out and crank it over. Did you add much oil or anything to it since it got flooded?
 
Well lots of wd-40 won't hurt, but you need to leave the plugs out and let it spray out. Is it still spraying or just gunk like small deposits? If it is just gunk, than I'd try with the plugs in to get it to fire. If it is spraying lots keep turing over for 15 seconds bursts and rest for a minute in between so as not to hurt the starter. How is the spark by the way?

Karl
 
spraying out lots of gunk, not just small deposits. spark is there, when i hold plug to block so i know coil is ok just seems like a lot of sludge
 
Have you tried to fire it with plugs in it yet? It won't pull any fuel or oil in it with the plugs out, as they are needed to raise the compression and pull in fuel and oil. Install clean plugs and fire it. If it doesn't fire pull the plugs clean them, reinstall them hand tight, choke it and see if it fires than...If it fires tighen the plugs and try it again.
 
I have tried with the plugs in, with starter fluid, without starter fluid, choked, not choked, each time the plug comes out coated with crap
 
How about putting a heat lamp on the motor for a while? I wouldn't leave it un attended but perhaps it would help in the vaporization of all the water and maybe get it to pop off a few times and help blow it out?


just an idea..........
