ART###Thrust is simply a static measurement of pushing or pulling power, and
higher thrust does not necessarily mean greater speed. Speed is a factor of prop pitch and motor R.P.M. Given motor R.P.M. under load, and Minn Kota's 4" prop pitch, the approximate speed that a motor will push/pull a small boat can be calculated.

Lastly, what is the top speed of a trolling motor?
The maximum speed of a trolling motor is 5 mph regardless of how many pounds of thrust.
Further, can you Overvolt a trolling motor? Re: Overvolting a minn kota trolling motor Jeremy Harris wrote: Power absorbed by the prop is proportional to the cube of prop rpm, so doubling the voltage doubles the rpm but the motor uses eight times the power. This means that motor current will increase by a factor of 4 if you double the voltage.
Together with, how fast is a 55lb trolling motor?
Assuming perfect riding conditions, the use of the best fuel i.e. the distillate marine diesel, and moderate load, 55-pound trolling motors are likely to attain a maximum speed of only 5 miles per hour. This would take around two hours for the deep cycle battery charge to get completely depleted.
How deep should your trolling motor be in the water?
A trolling motor's ideal propeller should be at a depth that keeps about 6 inches of water above the blades. In other words, the centerline of the motor and the prop shaft should be about 12-18 inches below the waterline, depending on the make, model and dimensions of the trolling motor.

Having a maximum speed of only 5 mph may seem slow, but it is what makes trolling motors ideal for fishing. Many people use trolling motors as their primary means of propulsion. This is popular on Jon Boats, dinghys, and other small personal watercraft.
A car battery is 12-volts and can power your trolling motor. However, the length of time you'll be able to do so will be a fraction of the time a designated deep cycle battery could do it, and the car battery will have a dramatically shorted lifespan if you choose to deep-cycle it for trolling applications.
Trolling motors can indeed be used as the main motor for a boat. Usually, transom-mounted trolling motors are used as a boat's primary propulsion, though these are generally more efficient on smaller boats at a low speed.
Essentially, you have a 12 volt motor. If you try to run it on 24 volts, you will burn it up. If, on the other hand, you have enough power to run your boat; but you simply can't run it for very long - i.e. short on duration; then go ahead and connect two batteries in parallel; as one of the other posts suggest.
Therefore, provided you chose a controller suitable for the motor you use, you can usually run a motor 12v motor from a 24v battery with no effect except that full speed is doubled.
Since 12V lead-acid batteries were originally designed for cars, there is a lot stuff that runs this way. 18V would be risky, I would not try to plug a 12V device into an 18V battery. But if you happen to have 18V for whatever reason, you can always use a DC-DC converter.
You can never have too much thrust and go with a variable speed. Not only is it more useful it also helps battery life. The one place that many people try to save money is on the electric trolling only to regret it.
For most jon boats, you'll need a trolling motor with 40 to 60 pounds of thrust. Of course, this will depend on the size of your boat, as well as the water conditions you typically encounter when boating. Trolling motors with greater thrust will handle rough waters better.
Can You Use a Trolling Motor to Push a Canoe or Kayak Upstream? The short answer is, yes, you can.
If you want to protect your trolling motor from substantial water damage, it's best to keep it away from heavy rain. Trolling motors that suffer water damage can lead to your motor not functioning properly. ... Ideally, we recommend using a waterproof material to cover the handle or storing the motor under a cover.

Almost 5 hours doesn't seem too bad, but that is really a max runtime in ideal conditions. Reality is likely to be less. If the battery is old, damaged or not fully charged then you will not get the rated amp hours from it, reducing your runtime. Significant cold or hot weather will also reduce your runtime.
Can You Run a Trolling Motor Out of Water? The short answer is, yes. The motor will run just as well out of water as if it were submerged. However, there's no reason to run a trolling motor out of the water.
If you have a short shaft motor, the top most part of the transom and the lower most part of the boat should be about 15 to 16 inches. For a long shaft, I think 20 to 21 inches is correct.
Too high usually results in low water pressure, prop letting go in turns, or lack of bow lift are usually the telltale signs. Sometimes porpoising is caused by too much bow lift and dropping the motor will give it more bite and make it worse.
So with 10 volts applied to the motor you can expect it to turn 1540 rpm. Of course it will draw much more battery power spinning in water than when in air. Minnkota and others use a prop with a pitch of 4 inches. That is the ideal boat , in ideal conditions, will move 4 inches each time the prop makes one revolution.
However, a 24-volt trolling motor should last at least 8-10 hours and may last up to several days before you need new or recharged batteries.
The battery is a critical element of your electric motor system. A high-quality deep cycle marine battery should always be used. ... Note: A starting battery is not suitable for use with an electric trolling motor. Starting batteries are rated in cold cranking amps (CCA).
A dual-purpose battery provides enough power to start the engine and turn it over, while also providing enough energy to keep your trolling motor running consistently. As the name implies, dual-purpose batteries can be used for both purposes.
The short answer is yes! We'll share with you step-by-step how to add a trolling motor onto your paddle boat, so you can navigate through waters effortlessly.
Lubricating Your Trolling Motor Next time you give your boat a wash, don't forget to lubricate your trolling motor shaft. This can be done after you have cleaned your trolling motor with water and a mild soap solution and wiped dry.
A trolling motor is complete self-contained like an outboard motor, but unlike the outboard motor, the trolling motor isn't going to be the primary source of propulsion. ... Electric trolling motors are usually used on smaller vessels because they don't require as much power.
12-volt trolling motors are usually less powerful than their 24-volt counterparts. This makes them less suitable for larger and heavier boats. Higher voltage systems, such as 24V or 36V tend to be more powerful and more efficient, due to the lower current flowing through the cables at the same power output.
