How fast will a 55 lb thrust trolling motor go?

How fast will a 55 lb thrust trolling motor go?
To use an example, a 55 lb thrust motor unit has a peak power draw of 40 amps. If you use the trolling motor for 6 hours at average 50% load of 20 amps, the trolling motor will then require a battery load of 120 Ah. (6 hours X 20 amps=120 amp hours).
Subsequently, question is, how many amps does a 45 lb thrust trolling motor pull? While the Minn Kota Endura C2 30 Freshwater Transom Mounted Trolling Motor (30" Shaft) model takes 32 amps/hr to get that 30 lbs of thrust, this one can do 30 lbs of thrust for roughly 18 amps/hr. 40 to 45 lbs thrust is roughly 29 amps/hr instead of the 42 amps/hr that those respective motors draw for the same thrust.
A battery with a 1 Ah capacity should be able to deliver a current of 1 amp or discharge for an uninterrupted 1 hour. As a general rule, smaller batteries are usually rated at 25 Ah to 50 Ah and bigger deep-cycle batteries could be rated as high as 100 Ah. There is no ideal amp-hour rating for a trolling motor battery. here
Keeping this in consideration, how long will a 12v battery run a trolling motor?
In fact two 55 pound thrust motors will not move you any faster than one 30 pound thrust motor. Higher thrust 12V trolling motors are designed for bigger heavier boats with larger payloads. The maximum speed of a trolling motor is 5 mph regardless of how many pounds of thrust. [links]

Most manufacturers will only list the amps/watts being drawn at top speed. You can calculate an estimate of amp drawn at different speeds using the max speed provided as your starting point. Note, these estimates do not factor in weight, wind or water resistance or other external factors.
You can expect 4-5 mph, assuming it’s a lightly loaded boat, no current and the weather conditions are perfect. here
Thrust is the most important thing to consider when buying a trolling motor.
However, if you want to go fast, you will have to use a much more powerful outboard or inboard engine. here
Water conditions, where and how you use your motor should also impact your decision. You need relatively little thrust on flat lakes, where the above-calculated minimum thrust will be just fine.
You can see a rough guide on how much thrust is required for different boat sizes in the chart below. more
Likewise, how many amps does a Minn Kota trolling motor use? The Minn Kota Endura C2 55 Transom - mount 12V 55 lb. Thrust Trolling Motor has a max amp draw of 52 amps/hr but only 5 lbs more thrust. 3. Because of the larger windings in the 50 lb thrust model, lower speeds use less amperage for the same thrust. here
But small trolling motors usually draw about 20 amps per hour (at 12 volts).
