Haswing Protruar Trolling Motor

Overall Rating
Battery Life
Noise Level

Finding powerful transom-mount motors is almost impossible—because they’re installed via clamps, it’s hard to design them in a way that they won’t vibrate too much, or create too much noise, when they’ve got more than, say 55 lbs of thrust.

Fortunately, Haswing has found a way with the Haswing Protruar series. The motors aren’t perfect—there can be a lot of noise and cavitation at top speed—but they are powerful and cheap. With a modification or two, you can solve the cavitation issues—and that makes these motors an excellent buy for anyone willing to give them a little TLC.

Like most transom-mounted trolling motors, the Protruar is incredibly easy to install. You’ll start by assembling the motor, which you can do in just a few easy steps:

  • Assemble the motor. This involves attaching the propeller, drive pin, and sacrificial anode to the motor. Fortunately, Haswing includes all the equipment you’ll need to do this—a propeller wrench and your fingers are all you need (fingers are not included).
  • Install the handle. This is used to control the motor—you’ll need to plug it into the top of the motor, insert it into the slot, and then secure it using the nuts and bolts provided by Haswing.
  • Attach the motor to the transom of your boat using the mounting clamps. Note that you’ll be able to adjust the angle and depth of the motor using the depth collar and tilting lever.
  • Wire the batteries—this is the hardest part. Remember to use deep-cycle marine batteries; use two 12V batteries for the 85-lb model and the 110-lb model. Haswing recommends at least 105 Ah batteries—those have worked well for us!

Using the Trolling Motor

The Haswing Protruar is very easy to use. There’s a telescopic handle that you use to hand-steer your boat, rotating it left and right. The handle itself can be rotated clockwise to go forward and counterclockwise to go backward. You’ve probably seen this before—very simple stuff.

You’ll find that the Protruar gives your boat an excellent range of motion—it’s also very powerful for its price. There is one notable problem, however—at its highest speeds, it’s prone to causing cavitation, which is incredibly loud.

We’re not here to scare fish—we’re here to catch them. There are several possible solutions to cavitation, including lowering your motor deeper into the water. You can do this on the fly—adjusting the tilt and depth are pretty easy (just make sure to turn off your motor first). You may find, however, that there are circumstances in which tilting or lowering your motor is not viable.

Fortunately, we’ve found a great hack from Peter Ranieri Fishing—a simple attachment can drastically reduce cavitation. In this video, he’s mounting it on a Watersnake Asp (an old favorite kayak trolling motor of ours), but the trick works just as well on the Haswing Protruar.

Comparable Trolling Motors

MotorGuide R5 Series: Very few companies offer transom-mount motors as powerful as the Protruar, but MotorGuide does. The R5 series is an almost direct analogy to the Protruar, though it tops out at 105 lbs of thrust. The power management on the R5 series is excellent.

Newport NV Series: The NV series almost makes it to the sheer thrust provided by the most powerful Protruar model but falls short at 86 lbs. The NV series is very well built, however, and resembles the Protruar series in terms of affordability.

What Sets the Protruar Apart From Comparable Motors

  • Sheer power: The most powerful Protruar motors are among the most powerful transom mount motors you can find on the market—and basically unbeatable for the cost.
  • Voltage: Most motors that provide over 100+ of thrust need at least three 12V batteries. The Protruar only needs 24V—that saves you some wiring, charging, and money on batteries, which is always nice.
  • Quiet: Aside from the cavitation and vibrations you might experience at max thrust, the Protruar is very quiet. That’s thanks to its brushless design—something we see on a lot of bow-mount motors but not as frequently on inexpensive transom-mount designs.
  • Cost: These motors are quite affordable—they’re not the cheapest that Haswing has to offer, but you’ll have a hard time finding a transom-mount motor that offers as much power for as low a price.

Other Features

  • Simple battery life indicator: There’s an easy-to-read battery life indicator; turn your motor off before reading it for the most accurate results. Haswing recommends recharging your battery when it hits 20%—a good idea, in our experience (don’t get stranded out on the water!)


The Haswing Protruar is an excellent option for anyone looking for a powerful transom-mount motor. Our recommendation is to opt for the two most powerful models—you can find 65 lbs trolling motors of about the same quality for cheaper, even among Haswing’s other lines (the Osapian is the perfect example of this—the aforementioned Newport NV Series is another great option).

We recommend looking at some modifications like the anti-cavitation modification we mentioned if you want to get a little more out of the Protruar—it’s a no-bells-and-whistles kind of motor.

In short, if you’re looking for a powerful, inexpensive transom-mount trolling motor, the Protruar might be the perfect fit!


What types of boats is the Haswing Protruar suitable for?

The Haswing Protruar is best used on medium to large vessels; it’s a great fit for Jon Boats. You can adjust the thrust and shaft size based on the size of your vehicle. To find the right size trolling motor for your boat, check out this guide from Minn Kota (it’s Haswing’s competitor, but the information is still great).

Is the Haswing Protruar saltwater compatible?

The Haswing Protruar can be used in both freshwater and saltwater, which gives it a leg up on a lot of its competition!

How long does the battery last on a single charge?

This depends on the size of the battery you purchase for your motor, as well as the max amp draw of the motor. Imagine you have a 100 Ah battery, and you use the 65 lbs thrust motor at its maximum capacity (50A draw)—you should get 2 hours of battery life. Of course, you won’t be using your motor at its maximum thrust at all times, and you’ll want to recharge your battery before it’s completely depleted. Keep these calculations in mind when you’re purchasing a battery!

How quiet is the Haswing Protruar?

Haswing says the Protruar operates at about 55 dB—about as loud as a typical conversation between two people. That’s true most of the time, and at lower settings, this is a fairly quiet motor. The vibrations and cavitation that you’ll get at max thrust, however, are pretty significant, and that can scare some fish off.
