    Suspected water in motor, will it need a rebuild?

    2009 GTX 255.. Ski sank and water was mixed in with the oil, in the water for 20 min. It took on water through a damaged resonator.

    Boat was serviced at the dealer. The dealer states that the motor may have been hydro locked however it runs normally now.

    So.. Do I need to have the motor rebuilt or not?

    Opinions???

    If you didn't crank it without the water in it, and it was removed properly you should be good to go.

    Did you try starting it with plugs in when full of water?

    No.. We got it out of the water, drained the bilge pulled the plugs and injector connectors and cranked it to get any water out. I did not see any water shoot out if the cylinders, just mist.

    Resonator failed.

    The dealer changed the oil a couple times and did a boil out.. I will run it a bit and change it again.

    After sinking my ski,and pulling it apart and looking at the bearings...i HIGHLY recommend pulling the motor and checking and cleaning everything out...yes most say you will be ok, and i along with most did as everybody else had done...flush with oil till the oil is clean....what people fail to forget is there is sand and particals in the water that are now in the bottom of your motor....what do you think happens when this crap gets sucked into the oiling system????It tears shit up......here is a picture of my bearings from my tear down.....NOW its a little more to tear a motor down than flush with oil,BUT if i would have tore it down then,i wouldnt be dumping big money into rebuilding it now.....

    Yeah it can do damaged ... I have had 2 that had carbon seal and drive shaft bearing fail which caused to sink ... Both been right and ran for many hours ...

    Had both motors stripped for other reasons and bearings where fine ...

    So can be a bit if a gamble , but if done right and should be fine ...
