🔍 Model Background

The Mercury SeaPro 350 HP V10 outboard (2023–2024) was engineered specifically for commercial operators and heavy-duty marine applications. Built on the same 5.7L naturally aspirated V10 powerhead as the Verado lineup, the SeaPro version is optimized for maximum durability, long service life, and reduced operating costs in demanding saltwater and high-hour environments.

Unlike the recreational Verado V10 models, the SeaPro 350 features heavy-duty gearcases, a high-output charging system (150 amps), and a commercial-grade calibration designed for better fuel economy and consistent performance under load. It supports Digital Throttle & Shift (DTS), Advanced MidSection (AMS), and Joystick Piloting when paired with compatible helm systems.

The SeaPro 350 is ideal for commercial fishing vessels, patrol boats, dive charters, and tour operations. It includes service-friendly features such as a top-mounted oil filter, no-cowl access door, and an extended service interval schedule to reduce downtime. Backed by Mercury’s commercial warranty and tested to withstand thousands of hours of continuous use, the V10 SeaPro 350 is one of the most rugged outboards Mercury has ever produced.
