Features

Features

  • SMARTCRAFT. BOATING WITH A HIGHER IQ: SmartCraft® is a full suite of digital technologies, fully integrated and totally coordinated. Gauges, sensors, vessel systems, computer-controlled features – one total package, one high level of control. Make your boating experience easier, safer and a lot more enjoyable.
  • ACTIVE TRIM: Active Trim makes boating easier and more enjoyable by automatically trimming outboard engines. Active Trim simplifies boat operation while improving engine performance and decreasing fuel costs.
  • VESSELVIEW MOBILE: VesselView Mobile allows boaters to use a mobile device (smartphone or tablet) to connect with their Mercury outboard engine(s). The plug-and-play module connects via Bluetooth, providing quick, convenient access to your engine’s data.
  • VESSELVIEW LINK: VesselView Link integrates your existing multi-function display with your Mercury engine(s) to place information and control at your fingertips. Its user interface is easy to navigate, and it integrates chart-plotter, sonar, radar and more into one display.
  • BIG TILLER: Big Tiller offers optimal control for 175 - 300hp FourStroke outboards. It incorporates a convenient power trim switch, close-at-hand shift lever and an optional digital troll control that adjusts engine speed in 10-rpm increments.
  • LIMITED WARRANTY: World-class marine products backed by world-class warranties! We stand behind everything we build, and we go the extra mile to ensure your Mercury experience is the best it can be – on the water and off.
  • MERCURY PRODUCT PROTECTION: Mercury Product Protection is an extended service contract for your Mercury engine and MotorGuide trolling motor that covers certain expenses caused by defects in materials and workmanship after the Mercury Limited Warranty expires.
  • MAINTENANCE: An exclusive Top Cowl Service Door on Mercury V8 and V6 outboards simplifies routine maintenance by letting you check or add engine oil without removing the top cowl. The Top Cowl Service Door also houses the latch release and a carrying handle. A graphic, hour-based maintenance schedule decal is conveniently located under the cowl and provides a quick overview of routine maintenance intervals and a QR code to access additional information. Easy access: All maintenance points are color-coded and accessible by removing only the top cowl.
  • CARB star rating - 3
  • Air induction - Performance-Tuned Long-Runner Intake Manifold
  • Recommended fuel - Unleaded Regular 87 Octane Minimum (R+M/2) or 90 RON 10% Ethanol Maximum
  • Controls - Remote Mechanical
  • Compatible with SmartCraftdigital technology

FourStroke Advantage

  • GO FARTHER: Advanced Range Optimization by Mercury Marine uses closed-loop fuel control to precisely adjust the fuel mixture and deliver the best possible efficiency.
  • KEEP IT STEADY: Adaptive Speed Control maintains engine speed (rpm) regardless of load or condition changes – such as rough water, tight turns, tow sports and lower speeds on plane – without having to frequently adjust throttle position, a first for the outboard industry.
  • LIGHTER BY DESIGN: Ounce by ounce, Mercury engineers cut pounds from the FourStroke outboards, ensuring each engine is the lightest in its respective class.
  • SMART CHARGING: Idle Charge battery-management prevents boaters from draining their batteries while operating multiple electronic devices. When battery voltage is reduced, the engine will automatically increase idle rpm to boost alternator output and recharge low batteries to the proper level.

FourStroke Performance Data

  • QUICK ACCELERATION: The high-displacement, quad-cam design of the V8 and V6 FourStroke powerheads generates plenty of torque, especially at mid-range.
  • SUPERIOR FUEL ECONOMY: Advanced Range Optimization improves cruise-speed fuel efficiency by automatically adjusting fuel delivery so seamlessly the operator won’t feel or hear it.
  • LIGHT AND COMPACT: Mercury V8 and V6 FourStroke outboards are the lightest in their respective class by at least 10 pounds and mount on 26-inch centers for broader fitment.

Intuitive, Innovative Features

  • ADAPTIVE SPEED CONTROL: Adaptive Speed Control maintains a desired rpm regardless of changes in load or conditions without adjustments to the throttle lever position – a first for the outboard industry.
  • SMOOTH AND QUIET: The V8 and V6 FourStroke engines are quieter and smoother than the leading competitor.
  • EASY TO MAINTAIN: The exclusive Top Cowl Service Door simplifies routine maintenance, letting you check or add engine oil without removing the top cowl. An hour-based maintenance schedule decal is located under the cowl, providing a quick overview of routine maintenance.
  • INDUSTRY-EXCLUSIVE BATTERY MANAGEMENT TECHNOLOGY: When battery voltage is low, engines will automatically increase idle rpm to boost alternator output and charge batteries to the proper level, protecting batteries from draining while trolling and operating electronic devices.
  • AMPLE CHARGING OUTPUT: FourStroke models feature a robust alternator that delivers 20 amps net of charging power at idle and 30 amps total at wide-open throttle.
