New V-6 FourStroke Outboard Line-up


Mercury Marine, the world leader in marine propulsion and technology, is pleased to introduce its new V-6 FourStroke outboard family and the expansion of its SeaPro commercial line at the 2018 Miami Internatio­nal Boat Show. The new engine family, which builds on the success of Mercury’s 75 to 150HP FourStroke outboards, features 175HP, 200HP and 225HP FourStroke outboards and a V-6 200HP 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. The new V-6 engines are precision engineered from skeg to cowl.

“This new platform will position Mercury to advance product leadership in the 175 to 225HP 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 power head and proven mid-section and drivesyste­m designs. Additional­ly, the 3.4l V-6 outboards are exceptiona­lly versatile, offering the option of hydraulic or power steering, black or white cowls, a significan­tly lower boat well intrusion than current product, in addition they offer digital controls, Analogue or digital instrument­s as well as a variety of accent panel colours. 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.”

For a large displaceme­nt FourStroke engine the new V6 is exceptiona­lly light weight at only 215kg - the lightest weight in its class. Lean and mean, the 3.4l V-6 FourStroke boasts Mercury’s best accelerati­on and twenty 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 fifteen percent compared to the closest four-cylinder competitor.

Other innovation­s that further differenti­ate the 3.4l V-6 are:

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;

“This is a great addition to the portfolio,” said Martin Bass, EMEA Mercury Marine president. “These engines are light and quiet - to have a V-6 that’s lighter than a fourcylind­er is just incredible.”

V-6 line-up of Mercury FourStroke­s (175 to 225HP)

Mercury’s 3.4l, 200HP FourStroke employs a large displaceme­nt in the 200HP class. At 215kg the engine is the lightest in its class, and is 16kg 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.

Superior Fuel Economy

In addition, the new engines provide fuel savings to the consumer. At cruise and at wide open throttle, the new fourstroke 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.

Additional Colour Options

In addition to Mercury’s legendary black engines, this new line-up offers white engines for the 200HP and 225HP outboards. For the first time, Mercury will also offer four accent panel colours plus ready-for-paint panels, which allow for personaliz­ation.

Noise, vibration and harshness (NVH)

The new 3.4l V-6 boasts excellent NVH quality, and represents 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.

200HP V-6 SeaPro

The Mercury SeaPro 200HP 3.4l V-6 four-stroke outboard employs a large displaceme­nt. At a very low weight. 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.

Like the 3.4l V-6 175-225HP FourStroke outboards, the new 200HP 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 fuelling automatica­lly when conditions are right. It does this so seamlessly that the operator won’t feel or hear it. ARO allows for optimal fuel efficiency, giving consumers the confidence to stay out on the water longer.
