The Mercury 115 FourStroke and the Mercury 115 Pro XS are both highly regarded outboard engines, each catering to different boating needs and preferences. Here’s a detailed comparison of their key features:
Mercury 115 FourStroke:
-
Quiet Operation: The Mercury 115 FourStroke is designed to operate quietly. It is 25% quieter at idle, 15% less noisy at cruising speed, and nearly 50% quieter at wide-open throttle compared to its competitors. This makes for a more pleasant boating experience, especially for those who enjoy serene environments.
-
Powerful Performance: With a 2.1L displacement and an 8-valve inline-four single overhead cam, this engine generates significant low-end torque. It has a full throttle RPM range of 5000 to 6000, which helps your vessel get up on the plane faster, providing excellent acceleration and power.
-
Efficiency: The engine is designed with optimized crankshaft oil dams and bearings to minimize resistance, allowing more power to run the engine efficiently. This design feature contributes to better fuel economy and overall performance.
-
Counter Rotation: The Mercury 115 FourStroke offers an option for left-hand rotation, which is beneficial when using twin engines. This feature provides higher horsepower and improved maneuverability, making it easier to handle the boat in various conditions.
Mercury 115 Pro XS:
-
Rigorously Tested: The 115 Pro XS is built to withstand harsh conditions, including humid and saltwater environments. This ensures continuous reliability during long-running hours, making it an excellent choice for demanding boating activities.
-
Fastest Top Speed: The 115 Pro XS achieves up to 3 mph faster top speed than its nearest competitor. With a high RPM range, this engine boosts performance, making it ideal for boaters who prioritize speed and quick response.
-
Quicker Acceleration: The Pro XS model is more than 1 second faster in acceleration compared to the standard 115 HP FourStroke motors. This quicker acceleration is beneficial for activities such as water skiing or getting up to speed quickly in various boating scenarios.
Summary:
-
Mercury 115 FourStroke: This model is versatile and suitable for a wide range of boats, including aluminum tiller, bass, deck, inshore fishing, runabout open bow, fish & ski boats, and rigid-hull inflatable boats. Its quiet operation and efficiency make it a great choice for general boating use.
-
Mercury 115 Pro XS: This engine is better suited for fiberglass vessels and aluminum boats in the 17’-18’ size range where top speed and acceleration are prioritized. It's an excellent choice for boaters who demand higher performance and reliability in challenging conditions.
Both engines offer reliable performance and are backed by Mercury's reputation for quality. Choosing between the two depends on your specific boating needs and preferences.
