Uh Oh... Water in the oil
Just picked up my Formula 252 from the shop. Went in for general check up and winterizing but the mechanic found about 3 gallons of water/oil in the crankcase. This is a fairly new situation because I just checked the oil the last run I had it out, about 1 1/2 hours ago, and it was clean and right on the full mark. He also said that he was having trouble getting enough anti-freeze into the motor. He ran 15 gallons in and the freeze temp was only down to +25 degrees. Apparently the anti-freeze was getting some into the pan and some out the exhaust since it clearly wasn't fully filling the block.
My initial thought is a head gasket problem or maybe an oil cooler failure. Of course the shop wants to do a repower suggesting a cracked block. Maybe that's true but before a go down the road of a $10k repair I want to try to diagnose the small stuff.
Thoughts?

I would get another opinion, sounds like there is a problem but that doesn't mean replace the engine. Don't wait too long the water isn't going to do the internals of the engine much good sitting there.

Don't worry about that. After he finished with the anti-freeze he changed the oil. There's no more water in the crankcase. Its safe for now but I want to dig around trying to find the problem before I start throwing major dollars at it.

If you have fresh oil and filter I would start over, go run the boat on the water and see if it gets water in the oil. If you run the boat under all load conditions with no water in the oil, take it to a different shop for winterization.

What engine do you have? 3 gallons of water and you did not notcie it running funny?
15 gallons of antifreeze? Your system holds 5 gallons tops! How was he testing for freeze in a closed system?
I agree with the last poster, make sure it is good for winter....I would pull the block plugs and exhaust plugs or have it winterized some where else. Check it out int he spring. Water in oil does not always mean bad block. Could be oil cooler, head gasket, cracked head, oil cooler.

unless your winterize guy has some crazy high pressure antifreeze pump I would think your oil cooler is fine (40 to 60 psi of oil pres verses 15 psi water pres)the oil will pump out and leave a mess in the yard or the lake 2c

No one said that all the water/AF is going into the crankcase but certainly some is. Could be, assuming a headgasket, that tsome of the coolant is dropping into the cylinder and out through the exhaust. That would allow the mechanic to run lots of AF into the motor and not that much making it into the lower block where the freeze temp is checked. I can buy that scenario. I'm not sure how to explain that AND coolant in the oil. That's the tough one....
