With it saying by Mercury I would say it was a Mercury outboard. What year is it??? I know when Mariner first came to the US, Mercury had a deal with Mariner they would be marketed under the Mercury Label for 10 yrs. This was later turned over by a court. So mercury should still sell parts for them.
