# How many HP is electric trolling motor?

Contents

Trolling motors are rated in pounds of thrust. As a rule of thumb 72 to 75lb. of thrust roughly equals one horsepower or 746W of electrical power. A typical 12V motor that draws 60A consumes approximately 720W.

## How many horsepower is 50 lbs of thrust?

To get the same 55 lbf of thrust as above, again with a 50% propeller efficiency, we get the exact same 0.49 kW or 2/3 hp.

## How much thrust is in a horsepower?

description. Thrust horsepower of jet engines and rockets is equal to the thrust in pounds force times the speed of the vehicle in miles per hour divided by 375 (which is equal to one horsepower measured in mile-pounds per hour).

## How many HP is a 55lb thrust trolling motor?

So every 746 watts is roughly equivalent to 1 horsepower. Using this formula the popular Newport Vessels NV-Series 55lb Thrust Trolling Motor is rated as 624 watts at the highest forward speed and so 624/746 = 0.84 and would be roughly equivalent to a 0.84 horsepower motor.

## How much weight can a 30lb thrust trolling motor push?

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.

around 5 mph

## What size battery do I need for a trolling motor?

Most trolling motor batteries fail due to lack of proper charging. We suggest selecting a 12 volt deep cycle marine battery with at least a 110 amp hour rating, usually a group 27 size battery. The higher the amp hour rating, the more run time you will receive.

## Why does thrust not have horsepower?

The amount of thrust that they produce is converted into horsepower units and added to the shaft horsepower. The result is called equivalent shaft horsepower. All aircraft produce thrust to overcome the drag of the aircraft. … In aircraft that have propellers (or rotors), the engine does not produce thrust directly.

## What is a pound of thrust?

Thrust is a force or a push. … Thrust is measured in “pounds of thrust” in the U.S. and in newtons in the metric system. 4.45 newtons of thrust equals 1 pound of thrust. A pound of thrust is how much thrust it would take to keep a one-pound object unmoving against the force of gravity on earth.

## What is the strongest trolling motor?

Minn Kota has introduced the most powerful trolling motor on the market featuring 112 pounds of thrust. “As the long-time innovation leader, we have developed a motor that delivers significantly higher thrust with minimal impact to size and weight,” Minn Kota Senior Product Manager Dave Maryanov said.

## How much thrust does a 2.5 hp outboard motor have?

The rule of thumb I go by is 1 HP = About 22 lbs of thrust. So it’s about 55 lbs of thrust for 2.5 HP.
