Re: Salt water in oil...head off..how to protect from rust.
Drain the old oil and put in new. Short of pulling then engine and removing the pan and cleaning, there isn't much you can do at this point.
If you ever have this problem again, and the engine still runs. Pull the impeller, start the engine without water and run for about 30 seconds. Change the oil and do it again. Then pull the head. Then you will have clean oil on all the crank, rod, and cam bearings before you take it apart.
