So I went for a cruise and everything ran perfect. I have twin Mercs inboards. I have an older boat and the engines are in the aft cabin with Vdrives.
I went down to the marina to do my normal once a week run my engines and my starboard would not start or turn over. I immediately thought battery or starter. The starter was already a bit weak but got a slow turn then nothing. Both were fine so I checked the oil and the engine was full of water nearly to the top of the dipstick. It had been sitting all week. We did have a major rain storm and the aft cabin can leak depending on the winds and there was a lot of that. I assumed the rain filled through the leak hitting the flame arrestor.
Panic mode sets in (engine is only 3 years old) I was able to drain all the water oil sludge mix(as much as dipstick oil changer could do). I drained and fogged all the cylinders, 1-4 wet 5-8 dry. Got the engine running again and am on oil change #5. I also changed filters.
Oil turns to milk the minute I pour new into the engine. Engine runs 100% smooth and has normal power but seems like the oil level is going up again? Strange thing is when I drained it last time even though the dipstick looked overfilled it drained just under 7 quarts. Exactly what should be in there?? Dipstick looked like I was overfilled by several quarts??
So what am I missing? If it was a manifold would it not take time to seep through the rings to get to the oil? Is the oil/water frothing to look more full than actual?
Head gasket would show overheating, blowby or something rough idle right??
Is the water just persistent? I cannot get to the bottom 100% but am very close with dipstick drainer... Any better suggestions?
Thanks for any help or advice. I have not checked compression just yet but is next on my list i believe...
