You asked the wrong question. You need to know how many amps the motor uses. Then you can multiply amps times volts and get watts. Then you can multiply watts by hours and get watt hours. (For house electricity you pay for kilowatt hours.) A kilowatt is 1,000 watts.
Depends on the size of the trolling motor. One of the smallest, a 30 lb thrust motor, would draw a max of about 30 amps at 12 volts. A 100 lb thrust motor would draw a max of about 46 amps. That is at full speed- slow speed, lesser draw. And yes, that does mean you need heavy wiring.
Usually trolling motors are 12 volts DC. You should find the amperage of the motor. Batteries are rated in amp hours. This means that the capacity of the battery will produce a certain amount of amps for a certain amount of hours. If your battery is 500 amp hours it will use any combination of amps and hours up to 500. If your motor draws 20 amps it will drain the battery in 25 hours or 10 amps it will take 50 hours to drain. By paralleling batteries you increase the draw down time. The amp hour capacities of added batteries are added together. Be sure and purchase a Deep Cycle Battery.
The time is immaterial. A 550-watt motor operating at 8.5 amps needs a voltage of 550/8.5 volts.
"Amps" is a steady thing. There's no such thing as "Amps per hour".The current through a 24-watt load is[ 24/the voltage across the load ] Amperes.
1000 watts/hr is equal to 1KW/Hr so according to the equation VxA=Watts 3736watts/230volts =16.24 amps
Ah is amp hours. It describes the capacity of the battery. A bit like the size of a fuel tank. The 12 Ah battery can deliver 12 amps for one hour, 24 amps for 1/2 hour or 6 amps for two hours. Or any other combination of time x amps that makes 12. The 35 amp hour battery is almost three times the capacity of the 12 amp hour battery.

Varies with the battery. I just bought a deep cycle battery last week at Walmart. 115 amp hour (trolling motor battery) for about $74.00. That is a lead acid battery. Other types and sizes will vary.

In Canada, under the Small Vessel Regulations, you may not tow from one hour after sunset until sunrise.

4000 ma is equivalent to 4 amps 1 amp is 1/1000 ma/hour means amp or ma per hour.

I have a 1980,115 Johnson Outboard on a Very Heavy 16ft Crestliner Fiberglass boat,I can get it up to 62kms per hour with 4 people in it .(I used a GPS to test this )
A btu is a measure of energy, but 18,000 btu per hour is a power of 5.22 kW, which is 5220/220 amps, 24 amps.
AMPS = Watts / VoltageOnce you have the Amps figured out, an amp hour is just one amp that's been run for one hour...Or2 amps that's run for 1/2 hourOr4 amsp that's run for 15 minutes...
