How big of a motor can you put on a kayak?
Match Motor to Weight & Performance A light, narrow kayak won’t likely need more than 30–40 lb of thrust. Heavier kayaks might need a more powerful motor. Selecting the right size motor is crucial, as a more powerful motor will drain battery power faster and necessitate a more robust attachment. Trolling Motor Thrust Rating For instance, a trolling motor with 30-55 lbs of thrust typically pairs well with a 12V battery with at least 50Ah, while motors with 70 lbs or more thrust may require higher-capacity batteries with at least 100Ah.If you have a 12-volt trolling motor, you can choose from several 12-volt options. If you have a 24-volt motor, you can use two 12-volt batteries in series or a single 24-volt battery. If you have a 36-volt motor, you can use three 12-volt batteries in series or a single 36-volt battery.Vessel Size Typically, these motors are rated by their thrust, measured in pounds. For example, a 55lb thrust trolling motor works well for a boat between 12 and 16 feet.
Is it illegal to put a motor on a kayak?
It is legal to put a trolling motor on a kayak in most places. But you can’t just attach a motor and go on your merry way. Making this addition to your kayak opens you up to more legal requirements and considerations. Possible with Most Kayaks With the proper mounting system, almost any kayak can be motorized.
What is the horsepower equivalent of a trolling motor?
Comparing Thrust and Horsepower If you do, you’ll usually find trolling motors measure up between a half horsepower and 2hp. As an example, the mid-size 55lb thrust trolling motor has the equivalent power of about 0. Converting thrust (lbs) to horsepower (HP) On average, it’s estimated that 72–75 lbs of thrust is roughly equivalent to 1 HP. However, keep in mind this conversion is not exact due to the differences in how the two types of motors operate.
How far underwater should a trolling motor be?
Submersion Rule: You’ll want the top of the motor submerged at LEAST 12 under the water to ensure adequate power and to prevent noisy cavitation which will scare fish.
How long will a 12V battery run a trolling motor?
As a general rule, we recommend a 110 amp hour (Ah) rating per battery for 6-8 hours of runtime. If you have a lower Amp Hour rating, you will want to calculate the runtime for your motor. The chart below will show the max amp draw for your motor based on the thrust. V 100Ah Lithium Battery Runtime: A 100Ah battery provides double the runtime of a 50Ah battery, offering approximately 6-8 hours for a 30-40 lb thrust trolling motor. For larger motors, such as those drawing 40-50 amps, the 100Ah battery could last around 2-4 hours, making it suitable for extended outings.In general, a 100Ah trolling motor battery will run a 55 lb thrust trolling motor for about 2 hours at full throttle, 4–5 hours at 50% speed, and up to 8–10 hours at 25% throttle, which is enough to meet a full-day fishing experience for anglers.So, with a 100Ah battery, you could expect about 2. In this case, with a 100Ah battery, you would get around 2 hours of run-time at full throttle with a 55 lb thrust trolling motor.
