Mercury 350CL 350HP – Verado V10 20″ Shaft Counter Rotation DTS in Black

Mercury 350CL 350HP Verado V10 DTS

The Mercury 350CL Verado pairs a naturally aspirated 5.7L V10 with a 20-inch counter-rotation shaft, built as the port-side companion for dual-engine high-performance center consoles. At 695 lbs, this DOHC powerhead is built for vibration-free running and heavy electrical loads.

Peak output holds through 5800-6400 RPM, backed by a 150-Amp alternator. The 2.08:1 gear ratio converts that 5.7L torque curve into strong hole-shot acceleration and top-end speed on high-performance hulls. Built in the USA, this engine pairs SmartCraft DTS with integrated electro-hydraulic power steering across turbulent offshore swells.

5.7L V10 Naturally Aspirated Power

The 5.7L V10 leans on displacement rather than forced induction, favoring durability and low-end torque hauling heavy fuel loads offshore.

Integrated High-Output Power Steering

Mercury’s integrated electric/hydraulic power steering removes external steering rams, giving effortless, precise control for docking multi-engine center consoles.

150A Industry-Leading Alternator

A 150-Amp alternator covers the electrical load of modern offshore boats running multiple displays, gyrostabilizers, and entertainment systems.

Mercury 3-Year Protection

Every Mercury 350HP Verado V10 carries a 3-year limited factory warranty with genuine parts through Mercury’s nationwide dealer network.

High-Performance Offshore Match

This 20-inch counter-rotation V10 is the port-side power solution for large offshore center consoles and high-speed deep-V hulls.

Maintenance & Longevity

Keeping the wet sump system topped off with clean oil preserves the V10’s tight tolerances. Flush the cooling system with fresh water after every saltwater outing. Pro Tip from the Shop: use the Top Cowl Service Door for daily oil checks and confirm the SmartCraft NMEA Gateway is communicating properly with the digital helm.
