water leaking from motor ??

[Mutt020]

Well, you start to get past one problem when you hit another...sigh...seems like it will never end. ok, here goes;

Motor was running a little rough, so I just cleaned the carbs and put it back together and what not. Put the earmuffs on, started it up, ran a little better. Still sputters and dies after about 20 seconds, but i'm gonna have to put this problem on the back burner.

I began to notice some water begin to leak out of the motor while it was running. The water was dripping out near the top of the case very near to the top right spark plug. (200 hp v6 evinrude o/b). Now i'm not all too familiar with boats and outboards, but common sense tells me that A) this is not normal and B) this is not good.

Turned the motor off and the water off and of course the drip stops. Soooo, anyone have any idea of what may cause this? I assume its not normal for water to be in this vicinity (near the upper portion of the outboard?) Maybe this might be a cause of the engine sputtering and dying at idle, if water was reaching the spark plugs?

Yep. Can't see the motor, so don't know where it's coming from. Could be leaking inside the cylinder too, causing missing.

Re: water leaking from motor ??

heres a couple of pics of where the leak was coming from. It was a fairly constant dripping leak while the motor was running. Any ideas or suggestions would be appreciated. It's not normal for water to be up in this part of the engine, is it? Any ideas of the cause/problem? I'd hate to take it to the mechanic and pay $100.00 just to have them diagnose the problem. Thanks.

i've been told that it might be a simple gasket that needs replaced on top plate that the spark plugs are in (cylinder head plate?). That would make sense, as water is leaking between the plate and the engine......that isn't my main concern though.

My main concern is whether or not water should actually be inside the engine (not too familiar with how these 2 stroke outboards work). Should water be circulating freely in the engine, maybe used to cool? I have no clue. It was also mentioned me something about a Water Jacket, and water being in it? Man I need some knowledge.

Looks like its going to be a head gasket - easily replaced. But, I am no pro, but I have just rebuilt my 115hp V4. Have you removed the spark plug for inspection to see if you got water into the cylinder?

Yeah, I concur regarding the head gasket. But again, my concern is whether or not it is normal for water to be up in this area. Anyone know what the "water jacket" is, or how it works? Does water flow in some type of sealed channel, surrounding the cylinder? That would make sense to me and explain why water is up in this area....but again, I need to gain some knowledge.

Mutt020,
Exactly. Water circulates around the cylinders and through the cylinder head in a separate "jacket". Very similar to the way water circulates through your automobile engine.

That would explain a lot then and leave me less confused. I was curious/scared of how water was coming up iinto the engine, thinking that it was filling the entire engine inside and then leaking out. Thanks for your replys.
