When I winterized my boat I was unable to turn over motor. Coil wire. It never started and I was freezing so I said screw it. Poured antifreeze in all the water tubes used starter to move water threw... So today I opened
Boat and checked oil, was really high. I drained it and it's not water... It's thin and silver? Not milky like water.

I'm guessing it's gas in the oil? I drained it using the dip stick pump. I know there is more oil in there. If I add 20-50 wt would that counteract the thinning properties of the gas? What would you do?

You might want to take it out and run the heck out of it just to be sure.

Did you smell it? Did it smell like gas? If it was gas, you need a fuel pump.

About a 2 year old
Motor maybe? I think it was new, but can't remember. Still breaking it in. A 3.8 converted to a 4.3. It was high on the dip stick, when I sucked it out I got a gallon and a 1/4 of fluids. It was mixing really
Good not like water and oil. Just really soupy oil.

What type of fuel pump, is this thing carb or efi? If it had a carb is it an electric or mechanical pump? The only way fuel can get in the oil on a carb engine is down through the carb, through the intake and then around the valves. Evev then if the float is stuck it will only be a small amount. And even then the rings must be worn for it to seep past them. Hardly possible on a "new motor" unless it wasnt broken in right and the rings didnt seat.

your answer is incorrect. If the mechanical fuel pump fails, it will usually fill the block from the area where the fuel pump is bolted to the block. this is a very common method of fuel pump failure.
