Do I need Mariner or Mercury Outboard Parts?

Mercury and Mariner outboard engines are essentially the same powerplants under two different nameplates. The name brand Mariner originated in Australia but through a couple of business transactions fell under the Mercury umbrella. Now, Mercury operates Mariner and the two brands are distinguished by application. Mariner is geared for fishing, Mercury is geared toward leisure boating. But when it comes to the parts, these engines share the same DNA and the same parts.
