A trolling boat motor need a fuse. Without a fuse, you would not only be risking your motor and your boat but also yourself and any passengers in case the engine starts burning. Without a fuse on your motor, you are stripping the protection needed for your wiring and opening the door for overheating and even worse, fire.
the reason that electrical fuses are always situated next to the battery is that conventional current travels from positive to negative, therefore, in case of high current, the fuse will almost immediately shut down the circuit.
We can find four types of boat motors that you can see in public, stern drive engines, jet drive engines, inboard engines, and outboard engines.
Outboard engines are the most common boat motors out there. They’re almost always located on the back of the boat, a part that’s called a transom.
- Trolling motors
Trolling engines are most used on fishing boats because of the discretions of the motor since it’s located underwater. They come in three different battery voltage; a 12-volt motor that’s capable of 30 pounds to 60 of thrust power and is mainly used in small boats, a 24 volt motor with 70 pounds to 80 pounds of thrust power that’s adept for boats like bass boats or flats boats. Finally, we have a 36-volt motor that’s efficient on really bog boats thanks to its 100 pounds of thrust power.
- What is a fuse ?
It is a fact that electric current may cause the objects that it navigates through to heat up. These objects may be lightbulbs, guitar amplifiers, a laptop’s battery, or even your coffeemaker. The problem is that when these objects overheat, they may become highly dangerous or even burn.
To prevent any overheating in devices and appliances from high electric current, we use a little thing called the electrical fuse. An electrical fuse prevents high electrical from overloading a circuit and therefore prevents the overheating of the electrical current.
The fuse protects the circuit but doesn’t exclude the possible Occurrence of short-circuiting.
The circuit breakers that we have in our house are considered a type of fuse. Whenever the electrical current is high and may cause overheating or fire, these circuit breakers Automatically turn on -and you guessed it- they break the circuit.
- Why use a fuse ?
A generic electric fuse is made of non-combustible material and contains a copper wire called a fuse wire (the wire might also b-be made of zinc or silver depending on the type of fuse). Whenever the current gets too high in a circuit for too long, the heat goes through the fuse wire that makes it meltdown, breaking the electrical circuit.
For example, let’s say that your toast maker has a ratted current of 25 Amps and has a fuse of 26 but the current going through it is at 28, at a certain point the heat will be high enough to melt the fuse wire, therefore protecting your toast maker from catching fire or from breaking down.
- Why would a trolling motor need a fuse ?
Every electric appliance and device has a fuse. Electrical fuses are only there to protect you both physically and financially. If you plan on rigging your trolling boat then you should know that not only do you need a fuse but it must be compatible with the motor you’re using. In trolling motors, the fuse wire depends on the motor thrust and the maximum amperage draw of said motor but also the distance between the motor leads and the batteries. In most countries, there are regulations for boat motor and battery installation and also, an overcurrent protection device (a fuse or a circuit breaker)
You simply cannot repair an engine’s burnt up wiring and you have to replace all the boat’s internal and external wiring.
