blown head gasket?

We purchased a 1988 Bayliner 2445. Engine looked great. We had it scheduled for a bilge upgrade, but looked great. We idled down the canal to the lake and then turned around and stopped so we could look in the engine compartment to make sure everything "looked" good. When we lifted the floor it looked literally like someone had dumped 20 lbs of caramel/chocolate pudding all over everything. On the top of the engine there is a metal plate. From the lower right corner of the circle plate there is a approx 1" round hose that connects to the top, lower right corner of the engine. That was off. By the way, what is this hose called or what does it do? (see pic)

The engine had never stalled and we did not try to restart. We called a tow and they towed us back to our dock.

So, number one thing we did right was making sure we had tow insurance through BoatU.S. - highly recommend to all boaters.

Now the questions - (our marine mechanic won't be able to look at the engine for a week or two) - the engine is a 230hp OMC I/O. The "pudding" doesn't wash off with mere water, so, definately oil, probably oil and water.

Has anyone had this happen? Any thoughts as to blown head gasket and/or cracked head? Does the fact that the engine was shut down BEFORE it over heated help us at all? Ball park costs? And, will it do more damage to sit like that for a week or two or should we call in someone else to look at it? Should we sell or repair? Let me know if you have more questions and since I already feel stupid enough, no, we did not check the dipstick before we bought her. The engine looked so crystal clear clean and the guy we bought her from DID start her for 5 seconds or less to show us that she worked AND did put her in the water for us and drove her to our dock about an 1/8 of a mile away. Looking for ANY information! Thanks!

Ayuh,... My Guess is,... This boat lives where it doesn't Freeze often,... But it Did last winter...
And the motor was never Winterized, or was done so improperly,...
Resulting in a Cracked Block....
My Guess is,...
You need a New Motor....

Can't wait two weeks, not good for the motor with water in there....hopefully it's only the head gasket!

Not likely that it is a head gasket, If there is that much water in there it is more than likely a cracked block. If the oil was just a little milky, it could be the manifolds/risers but with a larger volume of water, it points more to the block.

I'm with Bondo on this one, I think he hit the proverbial nail on the head.

Probably doesn't matter much at this point.

Re: blown head gasket?

Thanks for the responses - Here is another picture I took today. Keep in mind the engine was in immaculate clean condition before our little half hour journey on idle...

Any idea on what should be reasonable cost for what may need to be done? Does this repair need to be done out of the water or can it be done in the water?

Thank you kindly for your time - helps the pain lol.

P.S. - forgot to mention the slight rainbow sheen on the water when you look over the edge and the gasoline odor... that make a difference?

Re: blown head gasket?

Last labor cost I saw around here to pull and replace an engine was $1350. That is JUST labor, not including the cost of the engine. A rebuilt longblock will probably run you $2000 - $3000.

If you don't know when the exhaust manifolds and risers were last changed, you probably want to change those at the same time or you may shortly be buying ANOTHER new engine .....

Re: blown head gasket?

Ok, thanks again. Next question... If we go with a rebuilt engine, outside of hull issues (which there are none at the moment) would that be our biggest expense? Meaning, is it worth it to replace it? One of the receipts that came with the boat says it has a 2 yr old 'gear set' and parts - including 'clean and reseal lower and replace lower bearing carrier', etc, totalling about 3k. So, I assume THAT would not have to be replaced...

And no, this work would be done by a certified marine mechanic. Clearly, since I did not even check the dipstick when I purchased it lol...
