Question Water in oil LT1 1998 Pro Star

Here is the scoop,
I put the boat away last fall, winterized it as normal. ( but did not change the oil)
I was changing the oil this spring and before changing the oil I checked the dip stick, and there was a significant amount of extra"oil".

I did not run the boat, and drained the oil, I captured the first oil that came out of the pan in a clear container only about 1/2 inch in the bottom of a 1 gallon container was clearish, The rest was a very thin liquid/oil. In all it seemed to have about a 1/2 gallon of extra oil.

I changed the filter replaced the oil, ran it for about an 15 minutes drained the oil again, which showed signs of water "foamy" then drained the oil and filled it up fresh one more time.

I have ran the boat for about 45 minutes and it does not seem like the oil level is raising.

Has anyone had similar issues, does this sound like a head gasket. Can I run the boat for the summer "checking the oil constantly of course"

Any one have experience with changing head gaskets, could the water be coming in through the exhaust cooling system.

have you ever inspected the exhaust manifolds and risers by taking them apart?

16 year old boat - should inspecting annually now. very easy to change if needed. Are your manifolds and risers rusty - post a pic.

I'll Take a look when I get home from work and post a picture, there is definitely rust to my recollection at the manifold bottoms.

How would this get water into the oil though?

Thanks,

I have not taken them apart yet, I am going to order the gasket kit from "discount inboard marine" It was a bit to dark to take pictures but the manifold bottoms are definitely rusty.

Any tricks on getting the 2 rear Allen bolts out of the riser? My allen socket would not fit.
once off, what is the best method to test the or manifolds, or could it be the gaskets those looks pretty ****ty from the out side.

you have to take an allen wrench and cut it down.

Or get a ball-end allen wrench.
