If you can't extract it thru the dipstick tube or ? with a pump wait till you pull the motor (assuming your going to do so) draining it in the bilge is just nasty Tom

you can make yourself one of these-

thanks guys,ill try the siphon thing,problem is its not oil,its sludge,like mud from the water.wondering what to use to flush it all out and down to the pan,maybe just lifting out motor and cleaning it would be best,was just trying to find easier way.those are all great idea and il try them all before i pull motor,maybe make one of those buckets so i dont ruin my shop vac lol.

I have ran trans fluid in my block for a bit then drained. Trans fluid or mystery oil will act as a degreaser. I also put a small amount of mystery oil in gas with fill up and in fresh oil change.

I ran mine for about 20 or so minutes @180-200 degrees. Good and hot-probably wouldnt stomp on the throttle. I then drained filled with real cheap oil ran again then drained....Then put the good stuff in. If you dont have a long oil drain hose get one. Even if you have to lift motor to install, its worth it.
