The Mercury Mariner 2.2, 2.5, 3.0, and 3.3 2-stroke outboard motors were a popular choice for recreational boaters during their production run. These compact and powerful engines were known for their reliability and affordability, making them a great option for a variety of applications such as fishing, waterskiing, and cruising. They were available in a range of horsepower options, with the 2.2 producing 20 hp, the 2.5 producing 25 hp, the 3.0 producing 30 hp, and the 3.3 producing 35 hp. These engines were equipped with a variety of features designed to enhance performance and simplify maintenance. These included a single-cylinder design, a manual start system, and a fuel-efficient carburetor. The Mariner outboard motors also boasted a durable construction, featuring a corrosion-resistant aluminum alloy and a robust gearcase. The Mariner 2.2, 2.5, 3.0, and 3.3 2-stroke outboards were produced from the late 1980s to the mid-2000s. Despite their age, these motors remain popular among boaters on a budget who appreciate their dependability and ease of maintenance. They are still widely available on the used market, and many owners continue to operate these engines with great success. However, it's important to note that these motors are older and may require more frequent maintenance than newer outboards. They also produce a higher level of emissions than newer four-stroke engines. If you are considering purchasing a Mariner 2.2, 2.5, 3.0, or 3.3 2-stroke outboard, be sure to research its maintenance history and consider the potential cost of repairs.
