Yes, Mercury and Mariner outboard motors are essentially the same. Mariner outboards were originally built under a joint venture with Yamaha, but by the early '80s, Mariner and Mercury outboards became more similar than different. When electronic fuel injection was introduced in 1986, the transition was complete; the two outboards were mechanically the same. Many models of Mercury and Mariner are indeed the same unit with different decals, and parts are often interchangeable within the model year and horsepower range. However, there were a few models where Mercury used a larger diameter gearcase while Mariner used a smaller one, affecting performance and longevity.
It's also worth noting that Mariner was originally an Australian licensed company that re-badged overseas engines and sold them locally under the 'Mariner' brand name. Brunswick/Mercury eventually bought the Mariner name and took over operations.
While Mariner outboards are no longer sold in the U.S. as of 1999, they continue to be distributed internationally in markets where they remain popular. This ongoing availability ensures that support and parts for Mariner outboards remain accessible to users across the globe.
