I have a weekend of sailing ahead and last Sunday this is what it looked when motoring back. It's a 6hp four stroke japanese outboard in a well and it got a full service in spring 2025.

I do not remember it being there when motoring out of the marina. But it lasted maybe 5 minutes when i started it and went back. It was also spitting a bit of water as you can see. It's more gray than blue imo.

No suspicious noise or vibration and it went away after those ~5min.
