Re: 85 hp merc water in cylinder #4
Pull what head Tash? Have you ever SEEN one of these outboards with it's clothes off? It doesn't even have a cylinder head.<br /><br />Pete... what you probably have is a leak around the #4 spark plug at the water-jacket cover, not into the cylinder. That thing that looks like a head is just a water jacket cover.You can remove it to replace the gasket, but at a high peril of broken bolts. See if it still gives you water with the plug installed. If so - it's that exterior leak.<br /><br />Dry the area where the water is coming out REAL well and try to stop the leak with some sillycone sealer. Put a new plug in #4 while you're doing it so you can forget about changing that plug for the next 5 years. If it still weeps a little - no harm done, it's not getting in the motor.<br /><br />Now, if you're truely getting water OUT of the #4 plug hole with it running, then your issue is with the exhaust divider plates.<br /><br />-W
