What is the difference between thrusts and horsepower?

What is the difference between thrust and horsepower? Thrust is a force. Horsepower is a unit of power (i.e Force times Velocity). A turboprop engine provides thrust just like a jet, it’s just that shaft driven engines tend to be rated in horsepower. In other words the power available at the output shaft.

How much is a pound of thrust?

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.

How many lbs of thrust is equal to 1 hp?

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 does thrust compare to speed?

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. The formula for this is:
