water in fuel

[Scubaonline]

Can anyone answer this one ?<br /><br />Would a small amount of water in a fuel tank cause a 200 hp engine to seize solid with no other warning sounds or alarms ?

Re: water in fuel

This is what I think could happen with water.<br />A small amount of water in fuel tank might not be a problem at all right away depends how much and if it could get sucked into the fuel line water will go to the bottom but if we talking about boats and when using your boat this water could move around sucked into the fuel. To cause a problem all it has to do is get into any part of the engine. But if water is in the engine itself I would think that it could be possible if it has been getting in the engine for a long while and you didn't start this engine up in a long time and let water sit in there it could cause some damage and the results could be hard to tell what type of damage or extent of damage could be cause from this.

Re: water in fuel

Thinking about your question<br />Are you sure your engine is seize up. If that's not the problem The first thing I would check is the fuel filter to see if it has water in it and fix that problem why would you ask this leaves me to believe that you might have a fuel filter that has water in it and is causing your engine not to run I always check what is easy to check to rule them causes out.<br />I agree with papasage If there is a seize engine and it's from water the water is probally getting into the engine some other way.

Re: water in fuel

Thanks for your response. The engine had only 30 hours on it. The flywheel is locked solid. It started fine and no running problems. The fuel was new but there was residual fuel in the tank when we got the boat about 3 weeks before it seized. When taken out the spark plugs were rusty and - oil was sprayed through the ports and the flywheel we tryed to move with a bar at 100lbs to no avail.

Re: water in fuel

What ever type of engine you have, you always have to have the oil right like it says in the manual for your type or engine at all times one time of not having the oil right could be a big problem. If the engine was running and all of a sudden it did not run and seized up. Maybe a lubrication problem. I would check to make sure that this is not a gear problem to, that would be easy to check. I don't know what type of engine this is exactly? So I leave it up to you find how to check that put in neutral and check it, if you have not already. If you get a chance Tell us more of what type of engine this is inboard or outboard 2 cyl or 4 etc.

Re: water in fuel

I suggest that you tilt the engine up and pour some Marvel Mystey oil through the spark plug holes and let it sit for a few days. Then try a breaker bar on the flywheel nut. If that dosen't do it pull the heads and repeat this process. Don't be afraid of taking a block of wood and placing it in each cylinder and giving it a good rap with a hammer. Sometimes that will break it free. Inspect what you can with the heads off and let us know what you find.<br /><br />If you break it loose and get it running by all means install an in line water seperator in the fuel line.
