Hi lads, I recently bought an 18ft Shetland type boat, it came with 50HP Mariner EPTT 3 cylinder, (2002).Under the hood there is an oil tank (for obvious reasons) now im almost certain the chap I bought the boat off told me the engine was 4 stroke but after talking to a person whom I have great faith in he said it is 2 stroke. I want to make sure I put the correct oil in the tank so wat do yous wreckon?
