The Mercury FourStroke 115 XL CT SeaPro is a 4-stroke outboard marine engine, 115 HP / 86 kW with a 2064 cc 4-cylinder engine, designed for commercial fishing boats, rental tour boats, water taxis, and high-usage vessels requiring an extra-long shaft. Thanks to the Command Thrust (CT) gearbox system, it features the large gearcase and propeller of a higher horsepower engine. The SeaPro series is a specially developed Mercury line for commercial and high-usage outboard motors. Increased durability, Smart Craft integration, and long service intervals are optimized to meet the needs of commercial operators.
SeaPro engines aim for long life in saltwater environments with a reinforced cooling system and enhanced anode protection compared to standard FourStroke series. The Smart Craft gauge system allows for fleet-specific engine monitoring.
The extra-long shaft (572 mm (22.5")) allows the propeller to operate at the correct water depth on large fiberglass and aluminum boats with high freeboards. It is 64 mm longer than the standard long shaft (508 mm).

The SeaPro series offers a reinforced cooling system and increased anode protection compared to standard FourStroke engines. Smart Craft integration facilitates fleet management and engine monitoring. Long service intervals reduce operational costs.
Smart Craft transmits engine status, fuel consumption, temperature, and hourly operating data to a digital display. In multi-engine configurations, each engine can be monitored separately. The early warning system prevents unexpected failures.
SeaPro engines are designed for long service intervals. Oil changes should be performed according to manufacturer recommendations. In saltwater use, freshwater flushing after each use and end-of-season anode inspection are mandatory.
Mercury outboard motors are compatible with many fiberglass, aluminum, and inflatable boat models thanks to their universal transom clamp or transom mounting system. The only criteria are your boat's transom height of 572 mm (22.5") and the maximum engine power approved by the manufacturer. You can confirm compatibility with Clever Marin by sharing your boat model.
Share your boat model, transom height, and intended use — let's confirm together the suitability of the Mercury FourStroke 115 XL CT SeaPro engine for your boat and the correct shaft selection.
The electronic fuel injection system ensures flawless starting at any temperature and stable power output at all RPMs. Because it optimizes fuel consumption down to the millimeter, it both enhances performance and offers significant savings on long journeys. This allows users of all types, from small boats to professional fleets, to achieve greater range with less fuel.
Quiet and vibration-reduced operation.
Mercury's unique engine block design naturally absorbs vibrations and minimizes noise. This creates a comfortable environment for both driver and passengers during extended voyages. Whether for fishing, cruising, or professional use, the low noise level ensures a pleasant and stress-free experience on the water.
Durable, corrosion-resistant housing.
Special alloys and multi-layer protection are used against saltwater, humidity, and harsh environmental conditions. This structure not only extends the engine's lifespan but also reduces the need for maintenance. For users who want an engine that can operate with high performance for years, Mercury becomes one of the most reliable brands in terms of durability.
