    Motor "flush" or clean out question

    Hello all, i have a quick question. I have pulled the 1200 motor out of my Genesis to rebuild the top-end. I have been messing with it for a while and there is alot of "gunk" in the bottom end of the motor. Oil/gas and what not.

    What is the best and safest way to flush this crap out before butting it back together?

    Thanks.

    do you have the motor all the way apart? or are you just pulling the top end?

    The motor is out of the boat.. the top end is completely removed including pistons... all i have sitting there is the crankcase with the crankshaft in it...

    Take the halves apart and clean it with brake cleaner. Good time to change the seals anway.

    Well.. these pictures will explain why i am an IT Admin and NOT a photographer...

    I think i got a little water in the motor... when i first took it out to break it in one of the hull plugs was out and she took on alot of water.. i didn't think water got in the motor but it looks like it may have on the back cylinder.. this gunk was also up in the wrist pin bearings which would tell me that the motor ran like this for a bit.

    I think some of the "extra" gunk in the intake could also be from cranking that thing over and over working on it this past year and just built up. The PTO cylinder is nasty gunk.. the center is just gunky and the Mag side is clean..

    Thats what happens when water mixes with the oil/gas in the engine. I'd personally be concerned about the crank bearings. How long did the engine sit with water in it?
