Hi, wonder if anyone can help. I have a 4hp Mariner outboard, I'm not sure of its age but would think it was manufactured in the mid 90's. I used it at the weekend to power my tender and then took it back home having laid it down in the car. When I got it out of the car it discharged some thin black oil, not much but its the first time it has done this. I then noticed I had forgotten to switch off the fuel supply so I set up a tank and fired it up. Normally it starts first time but seemed to be flooded. This cleared ok and it ran fine.
Can anyone help and tell me where the oil might of came from? Aside from the gearbox does a simple outboard like this have any other places where oil may of come from?
