In addition, a uniquely inclined water tank ensures more powerful resistance than others in a flat position. As a result, get a more effective aerobic workout and cardio health on the upswing.

With a unique design, the blue water tank offers enhanced resistance compared to the other rowers sitting in a flat position.

Merax Frame

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

Merax Water Rowing Machine

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 on the front frame bars. This way, its footprint is reduced to approx. 25″L x 20″W (64 x 51 cm). Also, the water can remain in the machine’s tank when stored vertically.

The unit’s net weight is approximately 72 lbs (32.6 kg). So 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 on 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, its relocation shouldn’t be a problem for only one person once assembled. 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, the only color available for this model.

Seat and other parts

The Merax water rowing machine has a reasonably large seat. It is approx. 12.5″ (31.7 cm) wide and 10″ (25.4 cm) long. It provides enough contact surfaces for a comfortable workout. It stands at approx. 16″ (40.6 cm) above floor level. Therefore, entry and exit shouldn’t be difficult for elderly users or users with specific disabilities.

The top of the seat does not integrate any cushioning. However, it does have a contoured surface to provide optimal comfort and adherence. It’s a durable, fiberglass-reinforced ABS material, and as I’ve mentioned earlier, 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 stability. The rollers embed ball bearings to 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 like the seat, the footrests are made of durable ABS material. In addition, they have a pivoting design, allowing a slight movement of the feet during every stroke. Therefore, you can focus on your calves by stretching your feet 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 a mesh strap, which is highly resistant to abrasion.

Unfortunately, the pulling handle doesn’t have integrated HR pulse sensors. Therefore, you will need an HR chest strap to have your heart rate read.

Merax Water tank and resistance system

The Merax water rowing machine has 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 tank’s exact capacity is not specified, but it’s probably between three and four gallons (11-15 liters). Unfortunately, the tank does not have a resistance adjustment dial like First Degree Fitness rowers.

However, you can still add or remove water from it 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). Thus, it creates similar rowing to an actual 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.

Fitness monitor

The fitness monitor with the Merax water rowing machine features an LCD that divides into multiple sub-sections. It indicates time, SPM, strokes, distance (measured in meters), calories burned, and pulse.

In addition, the pulling handle doesn’t have integrated pulse sensors, so the monitor can only read your pulse via a wireless HR chest strap. Furthermore, the HR chest strap does not come with the rower.

Unfortunately, the fitness monitor does not have any online connectivity, nor is it 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 monitor will countdown from there.

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

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

Apart from the workout metrics mentioned above, the machine’s monitor displays room temperature, clock, and calendar. The monitor is battery-operated and requires two AA batteries, which come included. In addition, it also has a sleep mode to enter without machine input for several minutes.

Merax Assembly and Maintenance

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

Consequently, it shouldn’t take more than 30-40 minutes of your time — an essential toolkit with the assembly tools comes included. Also, the manual provides precise assembly instructions.

It is advisable to periodically treat the water in the tank with the supplied chlorine pills for maintenance. It would also help keep the rail clean to prevent 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!


  2. Wow, thanks for the in-depth article! I’ve wanted to get one of these, but I lacked the details I was looking for until I found your website! I’m not used to exercising, so do you think it’s okay for me to get one of these and start at a slower rate, consistently but not every day? I want to give my body a little time to adapt to the change. Do you think it’s still a worthwhile investment?

    • Hi Sandro, thanks for stopping by and sharing your thoughts with us. Yes, I think it would be perfect for you. However, it also would be best for you to go at your own pace.
