How Much Power Does a Trolling Motor Use?

The normal trolling motor is rated in amps rather than watts, but to convert it to wattage. You must first know the voltage of your trolling motor. Trolling motors are either 24 or 36 volts. For example, if an electric trolling motor draws 20 amps at 48 volts, the total draw is 960 watts (4820). Trolling motors can range in power from 100 to 400 watts or more, depending on the type of fish being pursued and the depth to which you are troll fishing.

It is important to know how much power you need before venturing out on the lake to choose the correct size trolling motor for your boat, because switching out tiny vs. large trolling motors is difficult while you are on the water. While some people choose heavy-duty batteries that run at 24 or 36 volts, others evaluate the size of the boat, how often they will be out on the water, and how easy it is to take off and put back on.

Deep Cycle Battery

Deep cycle batteries for trolling motors are rechargeable lead-acid batteries that are specifically built for deep discharges. They are also known as marine, gel cell, or plough trolling motor batteries. Deep cycle batteries have a number of advantages over normal wet cell batteries, including a longer service life and a greater number of charge/discharge cycles. The main disadvantage is that they are usually more expensive than their ordinary counterparts. A 12V 3.5AH deep cycle battery will typically last roughly 7 hours.

Trolling Motor Battery Capacity

A greater battery capacity will allow the fisherman to spend longer time on the lake before needing to recharge, but it will also add weight and cost. In general, the higher the amp/hour (AH) rating, the longer you can stay out on the water before needing to recharge your batteries. When selecting the right deep cycle trolling motor battery, other criteria such as voltage and average depth of fishing must also be considered.

Transom Mounting

A transom mount trolling motor is positioned on the back of the boat and connects to the battery through an electric wire. Because transom mount trolling motors have fixed front and back ends, turning at high speeds might be challenging.

Bow Mount

A bow mount consumes 43 amps on average. Because the transom is approximately 20-30% of the boat’s overall drag, a bow mount trolling motor will consume more power than a transom mount. Also check saltwater bow mount trolling motor

Trolling Motors: Bow vs. Transom Mount

Transom mounts are ideal for smaller fishing boats and canoes, but bow mounts are ideal for larger boats with deeper draughts, such as bass and drift boats, that need to haul their weight over heavy waves and windy conditions. Bow mount trolling motors are often more expensive than transom trolling motors, but many people believe they are well worth the extra money owing to their greater power and ease of operation.
