Engine Full of Water

[madman]

Well ... It was a bit windy last weekend so so save wear on the sails I motored around. Coiuld'nt stop as I had ran out of anchors. I also soon ran out of fuel. A nice man in a uniform gave me some more and left me tied up to a buoy to get sorted out. I tried to bleed the engine but it took too long so I decompressed the engine and whirled it round, it soon stopped! I then noticed water coming out of the air filter! After crawling around the bilges for a little while I founf a plug on a box on the exhaust system which I unscrewed, lots of water came out. I then replaced it. Soon after I managed to get the engine started. Question is : will the water in the engine have caused or is likely to cause any pernament damage, if so what should I do to limit any such damage?

oil change or 2 - and find out where it was coming from...........

It came from cranking the engine with the engine intake seacock open, the raw water passing through the heat exchanger was'nt getting blasted out through the exhaust as there were no exhaust fumes and therefor collected in the engine.

Youre bored again madman.........we can tell.

It was probrably the valve grommit on the amalgamator. Did you check this?

sry - meant to add the appropriate smile to save you spelling it out!

had salt water in a bigger Yanmar for about an hour, but not long enough to displace the oil, and it ran fine after an initial oil change and then another shortly afterwards.
Alternatively, and more by the book I understand, you can of course strip the engine, dry all the parts in an oven and reassemble..................

Sounds to me like there's water in the exhaust system. That's how it's supposed to be - otherwise the plastic silencer and the rubber exhaust hose would melt. What makes you think there was water in the engine?

Because there was water emerging from the air intake and I could'nt crank the engine until I had drained the shoe box thingie.

Well, I suppose that might be a clue;~) Running the engine is a very effective way of cleaning up the bores, combustion chambers and valves. Otherwise, in case water has got past the rings it would be wise to change oil and filter. Worst thing you can do is not to run it, so that piston rings rust to the bores.

Especially if you fly above the clouds!!!!

pray...

you didn't get water in the cylinders which causes a hydraulic lock and bends the con rods - cost me £1500 for a rebuild!

if it runs evenly afterwards you probably got away with it.

I had a boat once who's engine filled with water regulary. I left it on the seabed eventualy.

Re: pray...

He didn't get water in the engine when the engine was running, thus no bent rods etc. He did get water in the engine because he hand cranked it with the seacock open and got water in the engine via the exhaust valves which in turn was ejected out of the intake valves whist still being cranked. No real damage done, but as others suggest, oil & filter change, possibly some upper cylinder lube and run the engine well so that it gets hot enough to evaporate any residual water.
