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.
What lb thrust trolling motor do I need?
General rule of thumb: you need at least 2 lbs. of thrust for every 100 lbs. of fully-loaded boat weight (people and gear included). If things like wind or current are major factors where you fish, you’ll want a little extra thrust.
How much weight can a 30lb thrust trolling motor push?
So the maximum for a 30lb thrust motor would be 30*100/2= 1500lbs.
What does pound thrust mean?
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 fast will a 55 lb thrust trolling motor go?
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 fast will a 112 lb thrust trolling motor go?
How Fast Will A 112 lb. Thrust Trolling Motor Go? Ultimately a 112 lb. thrust trolling motor will still have a maximum speed of around 5 mph.
How deep should a trolling motor be in the water?
Setting your trolling motor at an appropriate depth will help it to function properly, while at the same time reducing the risk of it becoming damaged. Remember, the general rule is to keep the motor submerged 12 inches below the water line.
How big of a boat can a trolling motor push?
A beginning rule of thumb is that you want a minimum of 2 lbs of thrust for every 100lbs. For example, if you have a 3000lb boat, fully loaded, then the calculation is (3000/100) * 2 = 60lbs of thrust.
Will 2 trolling motors make you go faster?
Two trolling motors don’t increase the speed much. You will be soaring if you get 4 to 6 mph with two trolling motors. Even on a lake where you can only use electric motors, using one trolling motor is still the superior choice.
Do trolling motors scare fish?
Once trolling motor is on, it’s part of its environment. Fish get used to the sound, therefore NOT spooked. It’s the turning on and Off switch that will spook fish.
How many HP is a pound of thrust?
As a point of reference, remember that each pound of thrust is equal to about 0.05 horsepower.
How many horsepower is a pound of thrust?
So at 550 feet per second (375mph), each pound of thrust is one horsepower. At 825 feet per second (560mph), each pound of thrust is 1.5 horsepower.
Will a 55 lb thrust trolling motor?
Electric trolling motors are chosen by thrust. Higher pounds of thrust WILL NOT move a boat faster. 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.
What is 55 lbs of thrust in horsepower?
55 lbf = 0.245 kN, so (0.245 kN)*(1 m/s) = 0.245 kNm/s = 0.245 kW. That’s about 1/3 hp.
What size battery do I need for a 55 lb thrust 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.
How many pounds of 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.
