    Are you saying that you had water running to the engine on the trailer with the engine turned off?

    Oh dear, don't sound promising.
    You need to post more information for people to actually help !

    Not good Engine must be running before turning the water on and you must turn the water off before stopping the engine.

    Sorry to tell you this but your internals of this engine are toast.All the bearing races will have some form of rust already starting to appear which is the beginning of the end for an internal engine.

    Even if you removed all the water and moisture now it will start and run OK but maybe 1 -2-5-10 hours from now who knows your engine will start to tear itself apart.Either by a bearing locking up and bending a crank rod or a big end bearing heating up and shattering and all the fragments going through your engine and at worst destroying your lower crank cases,which are hard to find and expensive.
    The only parts worth saving now might be your pistons ,rings counterbalance shaft and magneto parts.Sorry for your loss
    If you get water into these engines its usually not a problem as we have sunk quite a few in the surf and dragged them out and got them going usually with in the hour and run them slowly at first and then flat out for a good hour to remove any moisture.One ski has been sunk over 5 times with more than 150 hrs on it thereafter .But this sounds like you have left it overnight ??

    Yes, as stated, you were filling the engine with water from the hose.

    It does not take very long at all if the engine is not running.

    That said, you can attempt to recover it since it was fresh water. Take the spark plugs out and ground the plug wires to the prongs on the top of the engine between the black RAVE caps.

    Dry the plugs with a lighter and set them aside. You may need new ones standing by also.

    Then, while standing as far back as you can and still reach the start button, turn the engine over. Water will geyser out of the plug holes.

    Do not hold the start button down for more than 10 seconds at a time and let the starter rest for at least a minute between cycles.

    When there is no more water coming out spray some kind of lube (Fogging oil is best but WD-40 type stuff will work) liberally into the plug holes as while turning the engine over by hand (pull the gray plastic cover off the back of the engine which will allow you to grab the PTO flywheel to do this).

    Then turn it over with the starter and repeat the process four or five times.

    Once you have only a small amount of vapor like stuff coming out when you turn it on the starter you can put the plugs back in, hook up the plug wires, and try to start it (make sure the fuel is turned on).

    If it will not start repeat the lube application and try again with new plugs.

    Once you get it to start let it run for about 15 seconds to make sure it will stay running when you hook up the water hose. If it will, then hook up the hose.

    For future reference, start the engine, then start the water. When finished, turn off the water, then blip the throttle a couple of times and turn off the engine.

    You have a five minute limit on the hose because the shaft seal has no lube and no cooling (the lake/ocean does this for you during operation). Allow at least 45 minutes to an hour between runs on the hose for it to cool. If possible, take it to a ramp and leave it strapped to the trailer and back it in (make sure it is deep enough) and run it like that (there is no time limit that way).

    You need to run it as much as you can to get it heated up to get all the water out that you can ASAP.

    The bad news is that fresh or salt, every 951 that I have seen flooded has lost a crank bearing within a year.

    Good luck to you. Remember that everyone makes mistakes, just some cost more than others.

    AHH thanks for that we actually removed the head straight away thinking cracked head or broken gasket and turned engine over a fair bit till there was no evidence of water in the cylinder. we will try the dose of lube this weekend and replace head gasket and head and fingers crossed it comes out running atleast.Sounds like time to look for ski numder 2.
