20 HP Mercury Outboard Motor Features
Mercury Marine’s new 20 HP outboard motor has been redefined as a new class of versatile, compact, and lightweight outboard. You get more comfort, control, and power in a smaller lightweight package. Read on to learn more about this product.
These outboards have a new tiller that is exclusive to Mercury. It’s ergonomically designed to provide comfort on a different level. It’s also fully adjustable allowing for an effortless single-hand control.
The 20 HP Mercury outboard motor uses a center tiller mount design that features an exclusive steering adjustment. It’s one of a kind considering it allows you to change the steering arc to accommodate the right or left operation.
This is done using a simple socket and Allen wrench. Also, you can fine-tune the outboard’s tiller arm horizontal angle up to 18 degrees.
The advantage of this feature is improved leverage and added comfort. This will ensure controlling the boat’s direction is a breeze. Suffice to say the engine can track effortlessly to the direction you want.
Another key feature is the exclusive right or left-hand throttle function for improved comfort and control. The throttle grip rotation matches the boater’s preference. There’s a simple throttle mechanism under the cowl. It’s used to switch the throttle grip for either right or left-hand use.
At the tiller’s handle end, there’s an easy-to-reach stop button. Its purpose is to easily stop operation.
Another great feature of this tiller is the easy-to-operate shift lever located near the throttle grip. There’s also a simple throttle tension knob. It’s designed to ensure you can fine-tune the throttle friction to suit your preferences.
Mercury 20 HP outboard motors deliver exceptional performance. This is to ensure superior fuel efficiency and improved boat handling. These lightweight powerhouses debut at 99 lbs. (45 Kg.), making them among the lightest 20 HP outboards in the market.
The engine is a 333 CC 2-cylinder 4-stroke. The configuration is a 2-valve per cylinder single overhead camshaft. It offers a maintenance-free valve train and low friction.
On the electric start models, you get a 12 ampere, 145-watt alternator generating 9 amperes when trolling. The core of the outboard motor is an EFI (electronic fuel injection) system. It allows the motor to start faster and easier while offering instant throttle response in any weather.
Manual starts are possible thanks to the innovative battery-free EFI control system. It comes with a built-in decompression relief rope. Starts are easy for anyone because of this system.
It requires less maintenance because it’s a pressurized fuel system. EFI also ensures the outboards run smoother by maximizing power output and lowering fuel consumption.
Under the cowl, there’s a maintenance schedule offering an overview of routine maintenance and a basic operation guide. The maintenance schedule has 100 hour and 300-hour inspections and checks. It includes a QR code for contacting Mercury Marine for more information.
Servicing the fuel system is a breeze. A powerhead oil filter drain hose is provided for draining the filter before removal. There’s a filter catch tray for catching any drips that may remain. All models have freshwater flushing if you use the garden hose connection on the engine’s side near the front.
Mercury’s pre-treatment painting and priming process are designed for saltwater use. It ensures the long-term protection of aluminum castings. Low-copper aluminum alloys prevent corrosion and deliver the best protection against the same.

Top 20 HP Mercury Outboard Motor Alternatives
From the above information, you have learned everything about the Mercury 20 HP outboard motor. If the product hasn’t piqued your interest, I got you covered.
I talked to owners and boating experts to find alternatives to the 20 HP Mercury outboard motor. From the information I gathered, I was able to come up with three of the best options. Check them out below.
Tohatsu 20 HP
The first thing I liked about this model is the multi-function tiller handle. It comes with PTS (power tilt switch), friction adjusting screw, front shift, and stop switch.
They are integrated into the tiller handle to make your boating experience comfortable. Additionally, there’s a carrying handle on the front that you can tuck away when you don’t need it.
Tohatsu 20 HP comes with a user-friendly, high-quality water separator. It’s a simple and unique separator that doesn’t need tools to drain the water.
Compared to the previous model, the tilting weight has been reduced by 26%. The weight reduction is the result of moving heavy components like the driveshaft and crankshaft 30 MM forward. This means you can easily tilt manually.
The outboard motor uses battery-less EFI (electronic fuel injection) operation. You can choose from a variety of options including remote, power, and manual tilt. The VST (vapor separator tank) is designed to integrate the fuel cooler, regulator, and high-pressure fuel feed pump.
- ECO Sport design and development concept
- Simpliq Technology
- Easily replaceable canister style oil filter
- CARB 3-star rating and EPA approved
- Only available in 4-stroke
Suzuki 20 HP
The DF20A is Suzuki’s 20 HP outboard motor. It’s the most technologically advanced portable outboard due to its state-of-the-art designs. For starters, it holds claim to being the first battery-less EFI 4-stroke in the world.
The motor uses a new fuel injection system with lighter and smaller components. Lean Burn Control technology ensures these products deliver reduced emissions and fuel economy. This means you get to go further for less. You also get a power tilt and tiller handle model.
To deliver more efficient and cleaner operations, Suzuki uses several of its advanced technologies. Furthermore, the technologies ensure the DF20A conforms to the RCD Directive 2003/44C of the European Parliament. It has also received the coveted 3-star rating from CARB.
The Suzuki DF20A is the first outboard to offer fuel injection. Additionally, all new components were designed as lightweight and compact as possible. They include the new throttle body, fuel injectors, vapor separator, fuel cooler, and inline high-pressure fuel pump.
- 3-star CARB rating

- Options for manual and power tilt
- Pricier than most in its class
Honda 20 HP
This is a reliable and efficient 4-stroke outboard motor. Combined with the long-stroke design it offers optimum torque in all RPM ranges.
Starting is easy thanks to a built-in compression release together with a digital CDI system to set ignition timing. This reduces the effort required to pull-start the outboard by 40%.
BF20 is convenient to mount and easy to transport because it’s the lightest 4-stroke model in its class. You will be happy to know it’s available with Power Thrust.
The design is developed to increase performance for heavy loads. Power Thrust uses a 4-blade propeller to create 15% more thrust in forward and 60% more in reverse. The result is improved performance and maneuverability.
There is an exhaust relief feature that increases power in reverse. It’s done by reducing cavitation around the propeller blades.
The exhaust relief is found above the cavitation plate. This allows the prop to run in exhaust-free and clean water. The engine also has the highest CARB 3-star rating. For optimal operation, the Honda BF20 uses PGM ignition. The system uses a microprocessor to accurately control ignition timing. It works not only during start-up but also across the entire RPM range.
- Uses PGM ignition to control ignition timing
- Available with Power Thrust Technology
- Easy to transport and mount
- Long-stroke design
- The tiller handle doesn’t have advanced controls
How Much Horsepower Do You Need?
The amount of horsepower you choose is going to depend on the size of your vessel. Here’s a quick guide to determining the best horsepower for your boat:
- Under 10 feet: for small craft, like canoes, dinghies, and sailboats
- 10 – 15 feet: boat of this size usually requires 15 – 20 horsepower
- 15 – 25 feet: this is the common size for recreational boats. If you travel for longer distances you need something in the 200 – 300 horsepower range. However, 75 – 90 horsepower is fine if you plan to stay close to shore
- Over 25 feet: you need to consider 200 – 300 horsepower
20 HP Mercury Outboard Motor FAQs
Answer: According to outboard testers and boat fans, this outboard has a pitch of 5 and a top speed of about 20 MPH. Take note that various factors such as boat weight and outboard condition may reduce the speed.
