# How much thrust do you need for a trolling motor

Contents

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 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 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 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.

## How many horsepower is 55 lbs of thrust?

If you’re getting the full 55 lbf of thrust at this speed, then your hull has 55 lbf total resistance at this speed. 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.

## Will saltwater ruin a freshwater trolling motor?

A freshwater trolling motor can be used without immediate damage in saltwater. However, there is increased risk for corrosion on metal components. Apply a thin coat of oil or grease to exposed metal and rinse the trolling motor with freshwater after using it in saltwater.

## Will 2 trolling motors make you go faster?

It’s not the typical “get it on plane, and get the bow out of the water” that we expect from the big gas motor. Two motors in the back will just push the bow a little higher in the air, and the stern will dig in deeper, slowing you down. The boat will be faster with a trolling motor if it’s level in the water.

## Can I put a bigger prop on my trolling motor?

Bottom line – a motor only has so much power and spin a propellor only so fast. If you try putting a larger prop on a motor that is not designed for it, the larger prop will simply spin more slowly so the net speed gain is 0 or negative.

## Can a 24V trolling motor run on 12V?

For a cable steer or hand controlled model this will not hurt the motor, but it will considerably affect the performance of the motor. … However, an electric steer motor, such as, the PowerDrive, Terrova, or Ulterra cannot be used on lower voltages.

## 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 long will a trolling motor run on a deep cycle battery?

Thereof, how long will a trolling motor run on a battery? If you use the trolling motor for 6 hours at average 50% load of 20 amps, the trolling motor will then require a battery load of 120 Ah. (6 hours X 20 amps=120 amp hours).

How long will a 12v battery last with a trolling motor?

Amp Hours Amp Draw Hours Use
100 40 2.1
100 50 1.7

## How fast can a jon boat go with a trolling motor?

Having a maximum speed of only 5 mph may seem slow, but it is what makes trolling motors ideal for fishing. Many people use trolling motors as their primary means of propulsion. This is popular on Jon Boats, dinghys, and other small personal watercraft.

## 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.

## Can I shorten the shaft on my trolling motor?

Yes, in some cases but to maintain the warranty on your motor we recommend it be done by an Authorized Minn Kota Repair Center. Some models cannot have the shafts shortened.

## How shallow can a trolling motor run?

2. If your boat has a poling platform, an 18- to 21-foot pole is fine for water 5 feet or shallower. If you fish deeper water, opt for a 23- or 24-footer. A longer pole allows more hand-over-hand propulsion without picking the pole back up, reducing both effort and noise.
