I have a 2012 Mercury 115 4-stroke. It is kinda new to me. I ran it a few times over the summer and went to change to oil (ran on muffs to warm up before draining oil) a few weeks back and there was a little water in the oil. I replaced the oil and let it set for a few days. Ran on muffs for a few mins, then drained a little (maybe a cup or two) oil out. There was water in oil again, but just a little and oil cleared up quickly. So I topped off oil and ran on muffs for about 5 -10 min. Let it set for 3 days. Went to drain a little oil out and there is a bunch of water in the oil. See photo.
What are my next steps for figuring out what is going on? Compression test? Leak down?
