MERCURY AND NITRO: A WINNING COMBINATION
reach a desired location, select an outboard that offers more speed. If, however, you own a small boat and fish lake systems, speed might not factor and the maximum-rated horsepower might not be necessary. You might decide to add a smaller ‘kicker’
motor, particularly if you troll, where the speed of the boat and lures is of critical importance. Using a lower-horsepower engine intended for trolling will allow you to tailor the boat’s speed. This is where Mercury’s 9.9-horsepower outboard, the standard by which all small four-stroke motors are measured, is perfect. It is lightweight and portable (only 83 pounds!) to suit small boats. However, it packs a wallop of power via Command Thrust (CT), which delivers the level of thrust, power and control that bigger, wider, heavier boats demand. With CT, a taller gearcase puts the prop deeper, below turbulent water, for improved performance, while a low 2.42:1 gear ratio delivers the thrust and manoeuvrability that big loads demand. An oversized anti- ventilation plate prevents air from being drawn into the prop, which increases efficiency. Using a 20% larger prop increases control, especially at low speeds. Mercury’s 9.9 with a four-blade prop allows anglers to finitely control boat speed and keep the boat running at the pace that’s right for the fishing conditions,. Selecting the right propeller is a vitallly
important step in ensuring performance for your motor. Too often, people select a prop solely to make the boat go faster. That can be a mistake, according to Mercury experts. Boats are frequently over-propped, which can cause a boat to run sluggishly and damage the engine’s gears. Dirk Bjornstad, brand director for Mercury Propellers is forthright when it comes to prop selection: “Determining the correct pitch is the most important thing,” Bjornstad says. “It’s crucial to performance. For best performance, pay attention to factors such as pitch, diameter, blade geometry and the number of blades i.e. three or four. Three-blade props are typically good for general purpose, providing decent acceleration and good top-end speed, while four blades enhance acceleration and mid- range handling and get the boat on plane faster.”
Mercury 40-60hp
Mercury’s 40 – 60hp outboards feature compact, single overhead cam designs and long piston strokes that produce more low- end torque for excellent acceleration, even when pushing a heavy load. The 60hp Command Thrust matches
the acceleration and fuel efficiency of other manufacturers’ more expensive 70hp outboard model, and Mercury’s state- of-the-art Electronic Fuel Injection (EFI) delivers reliable turnkey starts, improved fuel efficiency, instant throttle response and protection against low-quality fuel problems.
Mercury 75-115hp
Tuned for maximum acceleration and throttle response, Mercury’s 75, 90 and 115hp
Mercury FourStroke 115 EFI Prize
n Model: Fourstroke 115 EFI n Horsepower: 115 hp (84.58 kw) n Dry weight:181 kg n RPM: ranger 5800-6400 n DisplacementL: 1732 cc n Cylinder layout: In-line n Number of cylinders: 4 n Alternator system power: 630 watt n Alternator type: Fully regulated Belt-Driven
FourStrokes deliver incredible power in a lighter frame (the 115 weighs 20 pounds less than its closest four-stroke competitor).
Less weight and high displacement
mean Mercury’s 75, 90 and 115 FourStrokes generate abundant torque and immediate power. Because they don’t have to work as hard as heavier engines or those with lower displacement, these engines make boats plane faster, accelerate better and provide optimal fuel efficiency at cruising speed.
“You need to take time to think about
the way you use your boat, weather, wave conditions, humidity and the water size and type, freshwater versus saltwater. You must also consider whether you need aluminium or stainless steel.
“As a general rule, outboards of 150hp and
above should have stainless steel props, while those below 150 can typically run safely on aluminium. Stainless props are significantly more expensive than aluminium, and customers often choose aluminium, a choice that can be detrimental to the engine’s performance.
“So take your time and get expert help
to make sure you match performance and power to suit your fishing.”
n Starting: Electric n Gear ratio: 2.33:1 n Fuel type: Gasoline n SmartCraft: Yes n Engine technology: 4 strokes n Steering: Remote - Big tiller optional n Fuel requirement: Unleaded 90 RON min. n Trim positions: Hydraulic Power Trim and Tilt n Induction system: 4-valve dual overhead cam design
Mercury 150hp FourStroke
These motors are simply stronger, lighter and more durable than other engines in their class, with massive displacement for the lightest four-stroke in its class. This engine’s compact, lightweight design
fits most transoms, including those with narrow engine wells and tight motor spacing, making this the perfect motor when you re- power your boat. The 150 FourStroke, which was introduced 2011, has been an extremely popular engine for competitive anglers.
Mercury 200-350hp Verado
No matter how you define ‘performance’, Mercury Verado supercharged FourStroke engines (175 - 350 hp) create a whole new set of standards. Verado handles all conditions -
temperature changes, humidity, and elevation fluctuations aren’t a problem in an outboard that turns harsh conditions into pure, all-season power. Verado delivers superior torque and acceleration across the entire performance range that tournament anglers demand, from hole shot to top end, and all with less fuel.
