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 a 55 lb thrust trolling?
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. Now, once again for the sake of argument (these figures might not be representative of your actual setup) let’s say your propeller efficiency on that trolling motor is 50%.
How many HP is 30lb thrust?
The HP equivalent of our motors:
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 thrust does a 2.5 hp outboard motor have?
In between were the Suzuki 2.5hp at 83lbs of thrust, the Yamaha 2.5hp at 78lbs of thrust and the Parsun 2.6hp at 70 lbs of thrust.”
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 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.
How fast will an 80 lb thrust trolling motor go?
How Fast Will A 80 lb. Thrust Trolling Motor Go? it is important to note that more thrust does not mean more speed. The trolling motor’s maximum speed is around 5 mph no matter how many lbs (pounds) of thrust it provides.
How many ft lbs is 1 HP?
1 Horsepower (Imperial Mechanical): 550 ft lbf/s. Approximately 745.69987158227022 Watts (SI).
How much weight can a 1 hp motor lift?
This means with 1 hp, you can lift about 550 lbs (250 kg) at a rate of 1 ft/sec, 1100 lbs at a rate of 0.5 ft/sec, 225 lb at a rate of 2 ft/sec, 1 lb at a rate of 550 ft/sec, and so on.
Can you run a trolling motor out of water?
Your motor is cooled by the water around it, while running it out of the water for a very short time would be OK, it would take a long time to drain the battery much running the motor out of the water with no load. Why risk damaging a very expensive TM to just drain the battery down.
How fast is a 2.5 hp engine?
Here are our results. Tohatsu 2.5 Two-Stroke ($630; www.tohatsu.com) power: 2.5 hp weight: 26 pounds top speed: 5.4 mph noise at full throttle: 84 dB-A. The Tohatsu 2.5 was the only two-stroke we tested. As expected, it’s the lightest and least expensive.
How fast will a 2hp outboard go?
Maybe 4 or 5 mph with no wind. The 2hp will serve you better than the trolling motor.
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 fast will 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.
How deep should a trolling motor be in the water?
The rule of thumb is that the top of the motor section should be submerged 12″. In general, shaft length selection is more critical with bow-mount motors versus transom-mount motors. Most boat transoms are similar in their distance to the water, and Minn Kota’s standard transom shaft lengths should be adequate.
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.
