VesselView 703

Mercury’s VesselView 703 incorporates the new Simrad SolarMAX HD display.

The bright, high-definition glass touchscreen display has a 16 x 9 aspect ratio for higher visibility, glare-reducing coating, and dimmable lighting.


VesselView 703 simultaneously displays information for up to four engines in an easy-to-read interface. The display provides up-to-date information for more than 30 engine parameters, including: Fuel Level and Range, Oil Temperature and Pressure, Battery Voltage, Water Depth, Genset and more.

Built-in features include a 10Hz GPS and chart plotter capability (regional electronic chart cards purchased separately). VesselView 703 also has an integrated echosounder and true dual-channel CHIRP. It also can be integrated with all the Simrad accessories for the NSS Evo3 product line, including radar, sonar transducers, fish finder transducers, AIS, VHF, Sonic Hub/Fusion Link, C-Zone digital switching and more.

A highly expandable system, VesselView 703 has the gateway functionality to allow SmartCraft data to be displayed on NMEA 2000 devices. It supports 16 languages and multiple unit conversions, and also features automatic notification of available software updates through GoFree Wi-Fi, which is integrated into the system.

Included in the VesselView 703 kit is Mercury’s VesselView Link, which is required to fully integrate the propulsion system and make the display truly multi-functional. VesselView 703 will be available in late May.

Kit pricing remains the same as for the VesselView 702 kit; no price increase is anticipated for 2017.

Skyhook Advanced Features

New Skyhook Advanced Features include:

  • Heading Adjust – providing joystick operators with the ability to adjust the heading lock in 1- and 10-degree increments while SkyHook is active, making vessel control even more precise.
  • BowHook – can be used to unlock heading and just maintain position, allowing the boat to point in whatever direction the winds and currents dictate. This feature is useful when a locked-in heading is not necessary.
  • DriftHook lets the operator maintain heading and unlock the position of the vessel allowing winds and currents to move the vessel along. Adjustments of 1- and 10-degree increments can be made while drifting when bundled with Heading Adjust.

Skyhook Advanced Features will be available for purchase as DLC through the GoFree Shop starting in late May. These features require Mercury’s latest Joystick system and initially, VesselView703 (also available in late May). Boaters will be able to purchase Skyhook Advance Features for VesselView502, VesselView702 and compatible Lowrance and Simrad displays after a software update in late 2017.

QC4v 860 and 1750 Sterndrives

Designed, developed and manufactured in-house, the naturally aspirated, 9.0-liter engine features Mercury Racing’s aluminum four-valve cylinder heads and dual overhead camshaft valve train. The QC4v family now features models ranging from 860hp to an astounding 1750hp.


The 860’s engine’s quad cam, four-valve heads are integrated with Racing’s proprietary V-8 cylinder block, packed with Mercury Racing-designed and specified hardware. The valve train, enhances engine performance and durability over a standard two-valve design, enabling the engine to produce 860hp at 6,800 rpm on 89 octane (Rec 90) pump fuel.


The engine’s 6,300 to 6,800 rpm operating range offers exceptional acceleration for its power rating. The higher rev limits expand the range of propeller options available for a variety of applications.

Mercury Digital Throttle and Shift (DTS) technology is standard on the 860. The DTS system also features one-touch Smart Start, automatic throttle synchronization and shadow mode for multiple-engine applications. Mercury Racing DTS Zero Effort controls are designed to provide an intuitive control experience – precisely signaling driver intent.

Rear-facing ram horn intakes direct induction noise rearward to reduce cockpit noise and enhance engine power.

  • Noise reduction in the cockpit for a more pleasant boating experience
  • Allows for tighter installation of staggered engines due to enhanced exhaust routing

New camshafts, exclusive to the 860, feature custom lobes for greater valve lift. This, combined with high-velocity cylinder head intake ports, provides maximum air flow to the combustion chamber. New pistons, designed exclusively for the naturally aspirated engine, respond to the fuel/air charge with an efficient 9.75:1 compression ratio.

The Mercury Racing-designed oil pan features dedicated baffling and a custom windage tray. That, combined with an engine-mounted oil pump, keeps oil away from the crankshaft, virtually eliminating parasitic power loss. Rigging and installation is also facilitated by not having a remote mounted oil sump.

Engine temps are kept at bay with an all-new, race-proven heat exchanger. Engine oil and glycol for the closed cooling system are routed around the engine via a series of tubes. The tubes are encapsulated in a casting filled with sea water, which serves as a coolant. The heat exchanger provides a higher sea water flow rate for enhanced cooling.

Mercury Racing designed an all-new hydraulic transmission specifically for the 860. Racing developed the new transmission to handle high torque and power levels, and to endure treacherous offshore duty cycles. At the same time, the transmission delivers smooth and consistent shifts, thanks to Mercury’s DTS technology. The compact design also minimizes overall engine package length in both drive-line and close couple installations.

The 860 comes standard with the Mercury Racing M6 surface drive. The higher capacity M8 sterndrive is optional. The 860’s 6,800 rpm rev limit offers rapid acceleration via Mercury Racing Pro Finish 5 and 6-blade CNC sterndrive Cleaver propellers.

In addition to the rear-facing ram horn intakes, 860 owners have an additional option when it comes to reducing engine noise. The 860 can also be configured with the exhaust outlets routed below water for reduced off-plane noise.

The 860 features black powder-coated headers with colour-matched pulleys. A total of 12 colour options are available for the engine, transom and drive.

The 860 is covered by a two-year factory warranty.


Mercury Racing’s new QC4v 1750 Competition sterndrive produces an impressive 1,750 hp. The most powerful engine ever produced by Mercury Racing offers massive torque, acceleration and top-end speed.


Designed, developed and manufactured in-house, the 9.0-liter engine features Mercury Racing’s exclusive aluminum four-valve cylinder heads and dual overhead camshaft valve train. The proprietary V-8 cylinder block is further packed with Mercury Racing designed and specified hardware.

The engine produces its 1,750 horsepower at 6,800 rpm on 117 MON VP C16 race fuel.

New turbochargers provide greater airflow for enhanced power and torque. The enhanced torque equates to unparalleled acceleration, critical for powering out of corners in highly competitive closed course offshore powerboat racing.

Digital Throttle and Shift (DTS) features one-touch Smart Start and automatic throttle synchronization. Zero Effort Digital controls provide an intuitive control experience – precisely signaling driver intent to the potent powerhouses.

The 1750 is close-cooled for more uniform temperature distribution. Closed cooling, combined with a ball bearing supported compressor shaft, enhances 1750 turbocharger performance and durability as well.

Engine temps are kept at bay with an all-new race-proven heat exchanger. Engine oil and glycol for the closed cooling system are routed around the engine via a series of tubes. The tubes are encapsulated in a casting filled with sea water which serves as a coolant.

The heat exchanger provides for a higher sea water flow rate for enhanced cooling. Offshore racers and ski racers appreciate Mercury Racing’s proprietary pulse-separated exhaust tuning which keeps turbos “spooled up,” virtually eliminating throttle lag and low-end torque deficit.

The Propulsion Control Module (PCM), featuring Mercury Racing developed software, is the brain behind the brawn. Turbocharger boost is variable. A boost control valve, electronically activated by the PCM microprocessor, continuously adjusts the amount of boost needed to provide consistent horsepower.

The PCM also enables individual cylinder control. This ability to optimize fuel and spark timing independently for each cylinder enhances engine running quality, performance, fuel economy and durability. The use of eight independent ignition coils, one per cylinder, helps eliminate spark plug fouling.

The PCM drives Mercury Racing’s exclusive Engine Guardian System. Engine Guardian monitors engine functions to forewarn of possible problems that could lead to engine damage. This technology not only detects and alerts the boater of a problem; it also processes the data and reduces power to a maximum, safe level that allows the boater to continue operation with lower risk of engine damage. Engine Guardian relies on myriad sensors from engine temperature to cooling water pressure to protect these mighty power plants.

The 1750 comes equipped with a 95-amp charging system – providing an ample supply of power for an array of marine electronics.

The M8 drive and hydraulic transmission are designed to handle the 1750’s high torque and power levels – as well as endure treacherous offshore duty cycles. At the same time, the transmission, designed specifically for DTS, delivers smooth and consistent shifts.

The surface-piercing M8 gearcase, inspired by the legendary M6 drive, is two inches shorter to complement the lower engine profile. Lowering engine mounting in a boat results in a lower center of gravity for improved boat handling and overall performance. The M8 drive features the race-inspired twin pinion gear shaft design. First patented by Mercury for outboard racing back in the 1950s, the innovative design splits the torque load for a higher power capacity while maintaining a slim, surface piercing gearcase shape for maximum efficiency. The forged lower gears are larger and even more robust than those used in the world champion M6. Like the M6, the M8 is dry-sumped for maximum efficiency and power output.

The massive torque and power output of the new 1750 is transferred to the water via Mercury Racing’s Pro Finish 5 & 6-blade CNC sterndrive propellers.

400R Carbon Edition

Mercury Racing’s 400R Carbon Edition features contemporary layered surfacing sculpted out of lightweight carbon fiber composite.


Carbon Edition 400Rs share all of the industry-leading performance characteristics and creature comforts of its Phantom Black and Cold Fusion White 400R siblings, while providing an even higher level of luxury with this bold, aggressive visual treatment.

At a staggering 153 horsepower per liter, Mercury Racing’s 2.6L 400R is the most powerful consumer outboard ever produced by Mercury and provides the highest power-to-weight of all other four-stroke outboards in its class.

400R outboards feature a custom cold air induction system for improved air flow and power development, while significantly reducing intake noise for improved sound quality. A water-cooled supercharger is designed to reduce intake temperatures and significantly increase air density.

Electronic knock control enables the engine to safely run on 89-octane (95 Ron) fuel when the recommended premium 91-octane (98 RON) fuel is not available to maximize performance.

For the 2017 Program Year, Mercury Racing is providing an additional year of Platinum Mercury Product Protection (MPP) on all consumer 400Rs, for a total of three years of factory coverage.
