What would make water suddenly mix with the motor oil ?

The boat has been great and only has 900 hours on it in 30 years.

The boat would not start after the hurricane left my area. The motor
would not start after many attempts. I assumed it had just been soaked
from the 12 inches of rain.
I started checking everything from fuel air spark to oil. when I pulled
the stick it was milky gray.

I drained it asap and now have fresh oil in it. I have not attempted to
restart it until i get advise.

The engine appears ok to the naked eye. All the gaskets, elbows are ok
when looked at. My neighbor has the same boat/engine. he had water
enter through the carburetor spark arrestor.

The water would only come from a cracked intake/water cooling manifold
or an exhuast elbow right ????

Again, motor has been healthy and was tuned, oil change in June 2006.I
went for a three hour ride just before the bad weather arrived.

Thanks in advance.

Was it left in the water (at a slip) during the hurricane? If so, you may
have had water driven up the exhaust and into the cylinders from heavy seas
breaking on the stern.

Thanks for your reply. The boat was docked during the storm and the
stern was into the wind and waves. the water rose almost 4 feet at the
dock. my dock is at the dead end of a logoon.
i checked the boat many times to see that the pump was keeping up with
the rain water.
i did not think the water could be pushed up into the engine.

if this is the case then some engine cranking with the plugs out and
another oil change might save the engine ?

i have good spark and fuel delivery as of yesterday prior to finding
the water in the oil.

do you all think the motor is salvageable ???

another oil change

While cranking the engine over prior to finding the oil/water mix i
noticed water dripping from under the manifold. the water was dripping
only the same time as cranking was being done.

this could be the failed manifold as you suggested or the rain flooded
engine from the previous "helper".


again, i would like to know what others would do in this case ?

crank her with the plugs out and change the oil and try a restart or
just put another engine in over the winter ?

thanks

I'll second that.

Also, you might want to check the exhaust baffles to see if they are
stuck open or rotted through.

Unfortunately it can, particularly if there are heavy waves breaking against
the stern. There are exhaust "flappers" that act like check valves that are
supposed to prevent this from happening under normal conditions, but often
they are frozen open or simply rotted away. With 900 hours on the engine,
that is a distinct possibility.

The danger of trying to start the engine right now is that one or more of
the cylinders may have water in them.
Starting the engine could cause a hydrolocked condition, causing serious
engine damage. (water does not compress).

I think your engine is salvagable assuming no damage has been done other
than getting water in the oil.
I'll defer to the engine experts to give you the best advice as to how to
proceed from here.

Yes. And perhaps even another oil and filter change after that.

Yes.
Sorry for your problems, but I think it can be fixed.

Well, you kinda already answered his question - crank for
a while with plugs out, change oil, get her fired up, and make
sure to get it up to tempreture (to cook out all the moisture),
and run it for some time. Not sure an immeadiate second
oil change is necessary, the heat should cook it all out. But
certainly can't hurt.

Good advice. Get it good and hot when you get it fired up. The heat
will evaporate the remaining water. Then check the oil again. If it
stays clear after that treatment then I would not worry about the
engine. You might want to check your exhaust flappers. If it's an
merc i/o they will be at the top of the pipe going down to the drive..

THE BOAT CRANKED FINE WITH NO PLUGS. MOSTLY AIR/GAS CAME OUT.
I THINK THE MANIFOLD MIGHT STILL HAVE WATER IN IT ?
THE BOAT JUST DOESNT WANT TO START. IT IS ALMOST THERE. RUNS FOR A 15
SECONDS (POORLY) AND STOPS.
I WAS WONDERING IF WATER VAPOR IS STILL MIXING WITH THE FUEL ?

IS THERE A BOLT OR DRAIN I CAN NOT SEE ON THE MANIFOLD TO GET ANY WATER
OUT ?

RAINING AGAIN SO I WILL TRY AGAIN ON THURSDAY.

A small amount of water going through with the combustion mixture
shouldn't make it run poorly. In fact there have been various water
injection mechanisms in the past that deliberately inject a small
amount of water.

If it is running bad at this point I'd be more inclined to suspect wet
ignition issues. With all the rain everything is probably wet. Make
sure the inside of the distributor is dry and spray the wires down with
a little wd40. The other possibility is that you have gotten a lot of
water in your fuel tank as well. If you have a water separator dump it
and see how much water is in it.
