The new engine family features 175 HP, 200 HP, and 225 HP FourStroke outboards and a V-6 200 HP SeaPro commercial outboard.

The new Mercury FourStroke and SeaPro outboards are built on Mercury’s new 3.4-liter V-6 platform, which is designed to be powerful, light, compact and fuel-efficient.

“This new platform will position Mercury to advance product leadership in the 175-225 HP outboard category, and deliver across the board on consumer needs,” said John Pfeifer, Mercury Marine president. “These new outboards address applications across recreational and commercial applications, strengthen our core product lineup by building off the success of our recent programs and delivering on the requirements of our global customers.”

The 3.4L V-6 employs a large displacement, naturally aspirated powerhead and proven mid-section and drive-system designs.

Additionally, the 3.4L V-6 outboards are exceptionally versatile, offering the option of mechanical or digital controls, hydraulic or power steering, and black or white cowls on FourStroke-branded products, as well as a variety of accent panel colors. This versatility makes the new V-6 an ideal engine for repower applications.

“These outboards set a new benchmark in the marine industry,” said Pfeifer. “They are the quietest, lightest, smoothest, quickest, and most fuel-efficient engines we have produced in this range.”

The new FourStroke engine not only provides large displacement at 200 HP, but is also exceptionally light weight at 475 pounds (215kg) – the lightest weight in its class by more than 10 pounds.

Lean and mean, the 3.4L V-6 FourStroke boasts Mercury’s best acceleration and 20 percent more torque than the closest four-cylinder competitor at cruise.

Fuel efficiency is also unmatched – the new 3.4L V-6 FourStroke is calibrated to maximize fuel economy at cruise, yielding an advantage of up to a 15 percent compared to the closest four-cylinder competitor.

Other innovations on the 3.4L V-6 include:

  • A top cowl service door that provides easy oil check and fill (if needed) without removing the cowl, making routine maintenance easier than ever before.
  • Idle charge battery-management capability that protects against consumers draining batteries while operating multiple electronic devices, and best-in-class net charging output of 20 Amp at 650 RPM.
  • Adaptive Speed Control that maintains RPM regardless of load or condition changes, improving the driving experience.

“Based on what I’m hearing from our customers, we feel like we hit a homerun with the new V-6 FourStroke outboard lineup,” said Randy Caruana, Mercury Marine vice president North & Central America, and Asia Pacific. “What a great addition to the portfolio. These engines are light and quiet — to have a V-6 that’s lighter than a four-cylinder is just incredible.”

Mercury’s 3.4L, 200 HP FourStroke is the company’s largest displacement in 200 HP class.

At 475 pounds (215kg), the engine is also the lightest in its class, and is 35 pounds lighter than current product in this range.

With its performance-inspired dual overhead cam (quad cam) and four-valve design, the engine will reach higher speeds, faster.

In addition, this outboard is the only one of its kind that maintains rpm regardless of load or condition changes and provides a “sportier” feel to the drivers.

The new engines provide fuel savings to the consumer. At cruise and at WOT, the new four-stroke outboards take advantage of Mercury’s proprietary “Advanced Range Optimization” (ARO) calibration to generate greater fuel efficiency than the engine it is replacing and the closest four-cylinder competitor.

In addition to Mercury’s legendary black engines, this new lineup offers three shades of white available for the 200 HP and 225 HP outboards.

For the first time, Mercury will also offer four accent panel colors plus ready-for-paint panels, which allow for personalization.

The new 3.4L V-6 boasts excellent noise, vibration, and harshness quality, and represents an advancement from current products. Key NVH-enhancing features include:

  • The V-6 design is naturally balanced.
  • Multi-chamber air-intake quiets induction noise.
  • Fuel injector covers reduce high-frequency noise.
  • Specific cowl features prevent noise from reaching the operator.
  • The Mercury SeaPro 200 HP 3.4L V-6 four-stroke outboard sports the company’s largest displacement in its class. It’s also is the lightest engine in its class and is approximately 25 pounds (11kg) lighter than the engine it is replacing.

Like all Mercury SeaPro outboard engines, the 3.4L V-6 four-stroke is built for durability and reliability and is calibrated for commercial usage.

Similar to the 3.4L V-6 175-225 HP FourStroke outboards, the new 200 HP V-6 SeaPro outboard features “Advanced Range Optimization/ARO” calibration, which was developed by Mercury engineers to optimize cruise fuel economy.

The ECU will adjust fueling automatically when conditions are right. ARO allows for optimal fuel efficiency, giving consumers the confidence to stay out on the water longer.
