I'm in shock. I've had a flawlessly perfoming A4 since 2010 when I bought my boat. I change the oil every 50 hours and take good care of it. It's always run well. We set some sort of thread record here in 2010 with an "Overheating" thread when I first got the boat but since that was solved, no issues.
Last week I changed the oil for the spring. I started the engine and let it warm up to facilitate that. I then changed the oil. It came out black and looked like normal used oil.
Two days ago, I changed the impeller and today I changed the spark plugs. The old ones looked pretty good coming out. One had some soot on one side that almost perfectly split the little bent tab that sits over the electrode. But, they didn't look odd or fouled.
So after changing the plugs I started the engine and it started right up on the 1st revolution and idled perfectly. I had good waterflow coming out.
I then thought I'd go for a spin and shut the engine off to just peek inside the distrubutor cap to see how it looked, first ride of the season and all. Looked great.
Then I checked the oil level as I always do before heading out.
It was milky. I'm shocked.
Sorry for rambling. So, I don't know know where to start to try to figure out how water could have gotten into the crankcase apparently so instantaneously. Failed head gasket? Any good advice on how to start diagnosing?
