Today's outboard motors run on synthetic fuels, usually petrol or diesel. However, the boating industry's growth has seen advancement in fuel processing allowing you to switch between fossil fuels and natural gas. Such technology is essential for reducing the imprint of outboard motors on the environment while enhancing the machines' fuel-saving capabilities. Overall, an outboard motor is an excellent tool for anyone who is into boating. These motors come packed with several features for efficient functioning. Often choosing the right outboard motor requires a comprehensive understanding of the underlying components. They are discussed here to give you the insight you need.
Portable Fuel Systems
Versatility is a critical component of outboard motors. One way manufacturers ensure this is by fitting it with portable fuel tanks. The fuel tanks have manual priming bulbs that undergo a few compressions and relaxations when your boat's engine starts. This enables the priming bulb to continue supplying fuel to the motor for a while if your fuel pump fails. Certainly, it is an important feature that gets you out of trouble when you are on a voyage.
Your portable fuel tank also comes with a breather screw. Just as the name suggests, this screw allows venting of the fuel tank when operating the engine. Remember to keep it locked when moving the fuel tank to alleviate any spillage.
Fuel Line
The fuel line carries fuel around the motor for combustion to take place. The result is the torque needed by the boat to move from one point to another. When choosing an outboard motor, go for one with a self-locking fuel line and an automatic shut-off connection to the motor. It enhances safe operation when you disconnect the fuel line.
The Cooling System
An outboard motor generates lots of heat from the internal combustion of the fuel. Most outboard motors use a direct and raw cooling system that is dependent on water. The system draws up seawater by the action of an impeller pump installed within the motor's lower leg. Usually, the pumps are made of plastic and rubber materials capable of encountering water without corrosion.
The water drawn in by the pump passes through the motor's galleries and exits through the exhaust system. Simultaneously, a stream of water bleeds off from the system to show you that the cooling system is up and running. Some outboard motors also come with audio alarms and 'hot' light signals to keep you abreast of what is happening.
