Thrust is a very important element to consider when buying a trolling motor for your pontoon boat. It is usually measured in pounds and it is an indication of how powerful your trolling motor is. Therefore, it is reasonable enough to invest in a sufficiently powerful trolling motor which is appropriate with your boat’s size and weight. After all, you don’t want to spend a bad day with a sluggish trolling motor that takes forever to position your boat for casting. Here is a video outlining some of the features to look for.
The weight of your boat is a deciding factor
We have just said that weight of your boat plays a critical role in how the trolling motor performs. As a general rule, you can say that 2lbs of pounds per 100lbs weight will do fine. Therefore, if you have a 3,000lbs boat which is also fully loaded, it is safe to say that you’ll need 60lbs of thrust. But remember than when weight of the boat is calculated, you will take into consideration the potentially heaviest material that can be hauled on the boat. This may include luggage, fuel, gear, and passengers.
The stronger the waves and current, the more power you need to sail through. But if you prefer to spend the day in quieter waters, then the minimum specs of a trolling motor will suffice. Also, if you want to be able to fish many days in a row without charging, you will need to step up to something more powerful. For instance, investing in a 70lbs 24 volt battery motor will provide more run time than if you relied on a 40lbs 12 volt battery motor. After all, you want more run-time without interruptions in between.
Demand for power will increase with the size of the boat and motor respectively. This means calculating the maximum battery capacity that can be safely installed in the vessel to address the increasing energy demands.
Secondly, you will also need to determine if charging the batteries underway is a possibility. This added convenience could supply you with nonstop power. If you have a trolling motor marked at 24V, 54lbs, you will draw up to 28A. On the other hand, if you have a 12V motor with 44lbs of thrust, you will draw 36A. The idea is that bigger motors require more battery capacity, If you enjoy fishing whole day long, you’ll probably require a model that comes with a 24V battery.
Basically, when you address the above concerns, you will have the correct motor size in mind. It will save you from potentially replacing your trolling motor again when demand increases, and that’s a good thing since you don’t always want to keep spending money on your pontoon boat maintenance.
