The Pros, Cons & Price of Mercury 75 HP Outboard
With a wide open throttle (WOT) rpm range of 5150 to 5850, the OEDA 3 Star Mercury 75 produces 74.0 horsepower at 5500 rpm. The Mercury TLDI 90’s maximum torque is 135Nm at 4250 rpm, whereas the three-cylinder powerhead’s displacement is 1267cc and its maximum torque is produced at 4000 rpm. Therefore, the Mercury 75 hp has far lower output on paper.
The Orbital Engine Corporation of Western Australia invented the orbital combustion process (OCP), which uses a combination of stratified and homogeneous combustion in the Mercury 75 hp TLDI. As a result, when trolling, a boat uses extremely little gasoline while still having enough torque and power to quickly plane a hull. The variable-ratio oil injection has a large 4lt powerhead-mounted tank, and oil is delivered by an electric pump.
There are many reasons to buy a Mercury 75 hp outboard. Its single overhead camshaft, Optimax direct injection engine, Command Thrust gearcase, and Optimax hull design are just a few of the advantages. But what about the price? Are there any negatives to the outboard? Read on to find out! Here are some of the pros and cons of Mercury outboards. A brand new one will cost you around $9000, whereas a used one will range around $2000
1.7-liter model makes less than 115 HP
If you want more power out of your outboard motor, you can get a 1.7-liter Mercury outboard model. The company showcased several new technologies and engine designs at the 2014 National Marine Dealers Association Show. The 1.7-liter outboard is still the most powerful model in its class, making more than 115 HP, but you can expect even more performance. Mercury’s high-end XS model has a higher top speed and a much better rpm range. This means you can stay out on the water longer.
If you’re looking for a lighter four-stroke outboard, you can get a 1.7-liter Mercury outboard model. It’s lighter than a two-stroke, weighing just 399 pounds. This outboard has the same valve architecture as the Verados and requires no valve maintenance for its lifetime. In addition, Mercury offers a three-year warranty against corrosion thanks to a unique hard-anodizing coating process. And as a bonus, this outboard has 300-series stainless steel parts.
Regarding size, the Mercury 3.4-liter V6 outboard makes less than 115 HP, but it’s lighter than a Yamaha F200 or Suzuki DF200. The weight of this 3.4-liter outboard is lower than a 200-hp two-stroke engine, and the 1.7-liter version makes less than 115 HP. The Mercury V6 outboards feature naturally aspirated or supercharged engines, with an additional 200 HP Verados.
Mercury is working on a new V8 outboard engine, which could replace the supercharged Verado V6s shortly. Speculation suggests that the new engine could be a 500-hp turbocharged bent eight. This engine might make its debut at the Miami boat show. Other manufacturers, such as Tohatsu, are low-profile. In Australia, they sell fuel-injected two-stroke engines and modern four-stroke engines. Most models are offered between 2.5 and 250 horsepower.
Optimax direct injection engine
The Optimax direct injection engine for 75 HP Mercury outboard motor is ideal for fuel-efficient performance and increased power. With two-stage direct injection and a short combustion cycle, this engine delivers the power and fuel efficiency boaters expect from Mercury engines. Its low noise and emissions are another benefit. And its durability is legendary. Mercury is committed to providing its customers with the best value on the water, and the OptiMax direct injection engine delivers just that.
The Optimax direct injection motor for the 75 HP Mercury outboard motor uses atomized fuel droplets that are only 10 microns. The atomization process helps fuel burn more efficiently and achieve exceptional power and fuel economy. Its efficiencies are so impressive that Mercury recommends servicing it at a Mercury Marine Certified dealer or service center. For general maintenance, the Optimax has two valves and a fuel filter.
The fuel pressure regulator is held closed by a spring. It takes about ten psi to lift the diaphragm and force the fuel into the cylinder head. The air pressure is less than the fuel pressure, so fuel overcomes air pressure during injecting. The PCM or ECM opens the fuel injector and sends a stream of the injected mixture to the cylinder head.
Mercury’s Optimax direct injection system is the most fuel-efficient two-stroke outboard on the market. Its compact design and state-of-the-art direct-injection technology give it the ultimate performance on the water. The two-stage direct-injection system delivers more fuel and air to the spark plug than any other engine in its class. Its advanced fuel system includes:
- A heavy-duty prop shaft.
- Dual water pickups.
- An extensive list of corrosion-resistant components.
Command Thrust gearcase
The new Mercury Command Thrust gearcase on the new 75 HP outboard offers more power and torque than its predecessor while weighing less than half as much. The 115hp also features the industry’s lightest valvetrain, which is maintenance-free for life. In addition, the command thrust gearcase on Mercury’s 75-115 HP FourStroke outboards creates a larger footprint in the water, allowing the driver more leverage while steering and lifting the boat. The giant torpedo helps to hold even heavy boats on the plane, and the Command Thrust gearcase is designed to deliver the extra power and torque needed to pull a heavy boat onto a plane.
This new Mercury gearcase offers significant performance gains, reducing drag and boosting acceleration. This makes it possible to use more prop pitches, which adds to the overall power of the boat. And the new Command Thrust gearcase is compatible with all Mercury outboards. So what are the benefits of the new gearcase? Let’s explore how it will change the way you drive your boat. This article will give you all the information you need to make a decision that is right for you.
The Mercury Command-Thrust gearcase replaces the older “BigFoot” models, allowing for a lower gear ratio and larger bullet. While these gearcases are compatible with Mercury outboards from 75 to 115 horsepower, they’re not designed for high-powered Mercs. Instead, they’re better suited for heavier fiberglass skiffs and commercial boats with deep-vee hulls and center consoles.
Optimax hull design
The Mercury Optimax is a direct injection two-stroke engine. These engines are available from 75 horsepower to 275 horsepower, with Mercury discontinuing its old electronic fuel injection line this year. The Mercury Optimax is designed for smooth cruising and is not suitable for trolling all day. However, if you are concerned about the cost of the entire engine, a two-stroke engine will do the trick.
The Optimax hull design makes the Mercury 150 Four-Stroke engine lighter and more fuel efficient than its predecessors. This engine weighs only 510 pounds and requires a SmartCraft DTS digital control, which costs $1,326. Its exhaust manifold has free-flowing runners and is positioned far away from the engine for more excellent performance and lower fuel consumption. In addition, its composite valve cover and Command Thrust gearcase save weight.
Another difference between the Mercury Optimax and the Evinrude is the size and shape of the hull. The Mercury Optimax will travel far off the coast early in the morning, returning to your dock before sunrise. Both engines can travel consistently on low-resistance waters, but the Evinrude is more fuel-efficient. In addition, Evinrude engines require less electrical load and therefore do not need a battery to run.
The Mercury 115 FourStroke outboard provides ample power for its size. The 20-inch shaft “L” version weighs 359 pounds, 20 pounds lighter than its nearest four-stroke rival and 16 pounds lighter than the Mercury Optimax two-stroke outboard. The added displacement allows for better low-end torque and fuel efficiency at cruising speeds. It also features a single overhead cam valve train and is maintenance-free.
Active Trim system
Active Trim is a new feature on the Mercury line of outboard motors. This new system automatically controls the outboard Trim based on engine rpm and GPS speed. It was introduced at the 2016 Miami International Boat Show and has received rave consumer reviews. In addition, the price is expected to be less than $500. It may be more expensive than a traditional outboard, but its benefits make it well worth the extra money.
Mercury Marine is a $2 billion division of Brunswick Corporation. This company owns several leading boat brands, including Bayliner, Boston Whaler, Meridian, Sea Ray, and others. They recently announced their latest product, the 75-hp Mercury outboard price with Active Trim. The system will help the user reduce fuel consumption by adjusting the boat’s speed and power by reducing the amount of gas used.
It can improve fuel economy by up to 15%. It has dynamic trim capabilities and is compliant with CARB emission standards and U.S. and European Union regulations. An Active Trim system allows the expert trimmer to tune the boat more efficiently. The Active Trim system also has several other benefits, including reduced noise and emissions. The system can also be used in multi-engine installations. It can also be controlled by a mobile phone, making it convenient for boaters.
Another essential feature of the Mercury outboard price with Active Trim is its adaptive speed control system. Active Trim automatically adjusts the engine’s speed based on the boat’s speed. The system compensates for changes in boat load and operator demand. It will also prevent propeller damage during hard turns. This feature is standard on many of the Mercury outboards. Active Trim also saves fuel by improving fuel efficiency.
