I took the boat out this morning for another test / tune run. The boat ran very well except for one issue that I noticed. I have a mud colored oil in my bilge bay. I can see where it slowly dripping out of. It is dripping out of the starboard bottom side from inside the flywheel cover. There does not appear to be much water if any with it, as it is thick oil that was VERY hard to get off my hands when washing them in the restroom.
I know it could be the rear main seal, but I am confused as to where the "coffee" color is coming from. This would indicate that the oil has water in it. The drip is slow and it is not like a water drip, it is more of a slow goopy thick drip, so I assume the leak is not a big one, but I just can't understand where the water getting mixed in.
I went out and drained all the outdrive oil and it was full and water free, so it is not coming from the outdrive. I then leveled the boat and checked the engine oil. It looks like the engine oil is about 1/2-3/4 QT low. However the color of the oil on the dipstick is good, there is no indication of water in the engine so I am assuming the engine block is not cracked. so it appears that the oil is mixing with the water after it leaks out of the engine.
I removed the dust cover from the flywheel. This is what the "flywheel facing side" looked like. Judging from the pattern or location of the oil does this indicate where it might be coming from?
