Me neither, but I've gotten as little as a half quart out of it when draining it for an oil change. A friend of mine blew the l/u on his 200 HPDI and it was empty with no water in it. That was really when I began to pay attention. I check mine more often now, annually isn't good enough. I don't know factually what causes this, but I suspect poor seals that somehow let oil out but stop water from entering. I've never seen this problem on any other outboard, and I've worked on lots of them.
