Merax Water Rowing Machine | Challenge Your Intensity

The Merax Water Rowing Machine looks sleek, modern, and elegant overall in black and dashing blue. You can expect durability and consistent performance from this solid rower that supports user weights up to 330 pounds.

The blue water tank with a unique design offers enhanced resistance as compared to the other rowers that sit in a flat position. Also, this water rower with varying low to high levels of intensity challenges you and puts you in a race mode.

The large contoured seat is molded for your comfort and measures 12.5 x 10 inches and will make you feel comfortable during your long sessions. The footrests are 12 inches long, pivot safely with your feet, and include Velcro straps that you can adjust for your comfort.

The Merax Rower has a large smart multifunctional LCD panel with useful stats like calories burned, distance, strokes, duration of rowing, and heart rate. It has Recovery, Reset, Start/Stop, Up, and Down buttons. The quick Start and Stop buttons let you start rowing with the push of a single button.

Merax Frame

The Merax water rower features a durable steel frame with a sturdy and relatively long rail for the seat. Both the seat assembly and the railway should be able to support users up to 330 lbs (150 kg). Also, the rail is long enough to accommodate users up to 6’3″ (190 cm).

The fully assembled rower is relatively large. It takes approx. 78″L x 20″W (198 x 51 cm) of floor space, and on top of this, you have to add at least two feet of clearance on each side and at the rear, and at least one foot of clearance at the front, for safe usage and ease of access. Thus, it may not fit too well in a small room or apartment.

The rail of this rower does not fold like the rail of the Merax magnetic rower. However, the machine can be stored vertically, resting on the front frame bars. This way, its footprint is reduced to approx. 25″L x 20″W (64 x 51 cm). Also, when stored vertically, the water can remain in the machine’s tank.

The unit’s net weight is approximately 72 lbs (32.6 kg). It’s not extremely heavy, but it’s heavy enough to provide excellent stability. Plus, its rear stabilizer features adjustable levelers with rubberized pads. The front base also rests on (non-adjustable) rubber pads. These offer an excellent grip to the floor, preventing the unit from sliding or moving if you engage in a more intense workout.

The front base of the unit features a set of silicone wheels. Therefore, once assembled, its relocation shouldn’t be a problem for only one person. By using these wheels, you won’t have to handle more than 20 lbs (9 kg).

The machine’s frame comes with a corrosion-resistant and abrasion-resistant paint finish. The color used is black, this being the only color available for this model.

Seat and other parts

The Merax fluid rower has a fairly large seat. It is approx. 12.5″ (31.7 cm) wide, and 10″ (25.4 cm) long. It provides enough contact surface for a comfortable workout. It stands at approx. 16″ (40.6 cm) above floor level. Therefore, entry and exit shouldn’t be too difficult even for elderly users, or users with certain disabilities.

The top of the seat does not integrate any cushioning. It does have a contoured surface, though, to provide optimal comfort and adherence. It’s a durable, fiberglass-reinforced ABS material, and as I’ve mentioned above, it should be able to support users up to 330 lbs (150 kg).

The supporting frame of the seat is steel. It integrates three sets of rollers. Two are on top of the rail, and the third is placed under the railing to maximize its stability. The rollers embed ball bearings, so they provide smooth motion for the seat.

The machine’s footrests are not size-adjustable. However, they’re large enough to accommodate footwear of all sizes. They also have heel guards and adjustable straps with Velcro closure.

Just as the seat, the footrests are a durable ABS material. They have a pivoting design, allowing a slight movement of the feet during every stroke. Therefore, you can put more focus on your calves by stretching your feet a bit forward. Also, their rear stoppers allow a maximum angle of approx — 50 °.

The pulling handle is a simple, straight metallic bar, with rubberized grips for optimal comfort. It measures approximately 20″ (51 cm). It is attached to mesh strap, which is highly resistant to abrasion. Since it’s not a commercial-grade machine, the handle doesn’t have pulse sensors. To have your heart rate read, you will have to use an HR chest strap.

Merax Water tank and resistance system

The Merax water rowing machine comes with a solid polycarbonate water tank with an internal multi-blade impeller. As you pull the handle, the impeller spins into the water inside the tank, generating resistance.

The exact capacity of the tank is not specified, but it’s probably between three and four gallons (11-15 liters). The shell does not have a resistance adjustment dial like the First Degree Fitness E-520.

However, you can still add or remove water from it if you want to increase or decrease the overall resistance. There are six different levels of resistance marked on the water tank.

Like any other rower with fluid resistance, the Merax model delivers a dynamic response during rowing. Therefore, the resistance increases by the strength you put behind each stroke (the harder you pull the handle, the more resistance you will get). This creates a rowing feel similar to rowing a real boat through the water.

The level of noise generated by the machine is shallow. As a pointer, it won’t cover the sound of your TV set on one of the lowest sound settings.


The console unit included with the Merax rower features an LCD divided into multiple sub-sections. It indicates time, time, SPM, strokes, distance (measured in meters), calories, and pulse. The machine doesn’t have any pulse sensors, so the unit can only read your pulse via a wireless HR chest strap (sold separately).

The unit does not have any online connectivity, nor it is compatible with any fitness apps. However, it has two main programs, Manual and Race. The Manual Mode has two options. One, you can start rowing, and the unit will count the values of your workout. And two, you can set up target values for time, distance, strokes, calories, and pulse, and the unit will countdown from there.

The Race mode, as its name suggests, gives you the possibility to compete against the computer to test your level of fitness. This program has multiple levels of difficulty. Each level has its preset time/500m.

A Recovery function is also available on this fitness console. This program gives you the possibility to calculate your fitness level. Based on the heart rate at the end of the workout, it will provide you with a fitness rating between F1 (Excellent) – F6 (Poor).

Apart from the workout metrics mentioned above, the machine’s console displays room temperature, clock, and calendar. The console is battery-operated and it requires two AA batteries which are included. It also has a sleep mode to which it will enter if there is no input on the machine for several minutes.

Merax Assembly and Maintenance

The unit’s tank comes pre-assembled and attached to the front part of the unit. Therefore, you only need to connect the seat to the rail, attach the track to the front part of the frame, add the rear stabilizers, the footrests, and the console.

This shouldn’t take more than 30-40 minutes of your time — an essential toolkit with the tools needed for the assembly (is included). Also, the manual provides precise assembly instructions.

For maintenance, it is recommended to periodically treat the water in the tank with the supplied chlorine pills. Other than this, the rail should be kept clean to prevent any damage to the seat rollers.

  1. I like how it folds up for secure storage. 

    So the water tank holds about three or four gallons, I assume that added weight is why it increases the resistance.

    How many times a week should I use this exercise machine?  Every day?

    The seat looks comfortable.

    It seems this would be a good exercise for a good cardio workout.

    • Hello, Phil, the exact number of gallons is not specified, but it”s my guess it is somewhere between 3 and 4 gals. There are impellers in the water tank that creates the resistance as you row.

      You can add or remove water from it if you want to increase or decrease the overall resistance. There are six different levels of resistance marked on the water tank.

      Yes, you can use the Merax Water Rowing Machine every day for a good cardio workout.

      I hope this helps and Happy Holidays!
