Default Milky Oil, Please Help

I am brand new to the site guys, but I have a problem. I have a 23 foot 1997 Scarab. It has the 502 with procharger. I took it out this spring to just see how the winter had been on it. It ran and sounded fine, run around 78 mph on GPS not all she could do. Came back to dock and checked oil and noticed it was milky.

I thought it might be condensation, so I changed the oil a couple times and ran it, got milky again. I noticed a little hesitation on take off, could this be intake gasket. Overall performance is still good. May just haft to start with intake gasket and work to the heads and then intake.

One other thing, is I noticed that my flappers seemed to be worn out for my exhaust. Could it be reversion? Any help is greatly appreciated, love the site. I will post pics later.

when you winterized the boat,did you drain the exhaust manifolds?if not,you might have cracked them,that will cause reversion.seen it happen before.goog luck,let us know what you find,and welcome to oso.

then water may have have came in from bad flappers it takes a while to get rid of the milk on the stick.does it get milker every oil change are you changing filter also every time ?dose the oil level rise up after runing it out. try blowing a lot of air down the dip stick to move the oil a round to get a better reading. also pull the cap off the valve cover to see if it is still pump in milk while runing.
