Large boat motors may sometimes scare fish away before the boat even gets within fishing distance. For these situations, there are special types of outboard motors called trolling motors. Small and quiet, trolling motors allow boats to slowly and silently move through the water without scaring away the prey.
Trolling itself refers to a boat moving through the water at a slow speed with a baited line trailing from behind. This allows the bait to “swim” through the water and appear more lifelike. This technique can be applied to many different types of fish such as Bass, Salmon and Trout. While large boats with gas powered engines can troll, a trolling motor is usually small, and electrically powered.
The benefit of electric power is important because it limits the noise output of the boat. When cruising through a quiet lake, the virtual silence of an electric trolling motor becomes even more apparent. But as with everything else, there is a trade off. Trolling motors provide far less power and speed than their gas powered cousins. As a result, it can sometimes be difficult to control the watercraft with a small trolling motor.
As a rule, most experts believe that the most powerful motor within reason and budget is the best one to purchase. That way, it will provide enough power if the weather turns bad and the water becomes choppy and difficult to navigate. The extra power can really pay off.
