The Mercury SeaPro 350 XL AMS DTS V10 is a 4-stroke outboard marine engine, boasting 350 HP / 257 kW and a 5700 cc V10 (10-cylinder) engine, designed for commercial fishing boats, rental tour boats, water taxis, and heavy-use marine vessels that require an extra-long shaft. The SeaPro series is a Mercury line specifically developed for commercial and heavy-use outboard motors. Enhanced durability, SmartCraft integration, and extended 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 increased anode protection compared to standard FourStroke series. The SmartCraft gauge system enables 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 a standard long shaft (508 mm).

The SeaPro series offers a reinforced cooling system and increased anode protection compared to standard FourStroke engines. SmartCraft integration simplifies fleet management and engine monitoring. Extended service intervals reduce operational costs.
SmartCraft 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 extended service intervals. Oil changes should be performed according to the manufacturer's recommendations. In saltwater use, freshwater flushing after each use and an end-of-season anode check 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 572 mm (22.5") transom height and the maximum engine power approved by the manufacturer. You can get compatibility confirmation from Clever Marin by sharing your boat model.
Share your boat model, transom height, and intended use — let's verify together the suitability of the Mercury SeaPro 350 XL AMS DTS V10 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.
