The Main Features of Outboard Motors for Boats

Outboard motors are a single unit which comprise of the motor, the propulsion system and the subsidiary systems. The propeller unit of the outboard motors is mounted on the rear or the stern of the boat. The outboard motors provide the steering control as they can pivot around. This enables the control and the orientation of the propeller. They also have a fuel tank and controls are right on the body. This makes it easier to steer the boat.

Great for shallow waters

Outboard motors can also be pulled forward when the boats are in shallow places or they are been serviced. This prevents the propeller from getting stuck in the shallow waters or the seaweed. They weigh only about 12 Kgs or 26 lbs (approximately). They are highly portable and can be carried easily. One needs to just loosen the mounting clamps and carry it around. They also provide far greater speed than simply doing it with oars. You can attain a maximum speed of 15kmph or 9 mph on a small dinghy boat. For smaller boats, there's a manual pull ignition system. While for bigger outboard motors electric system is available.

Advancement in technology

The first usable and practical outboard motors were designed in 1909 by Ole Evinrude. Earlier, all the outboard motors were designed to use two stroke engines. With the rise in technology and environmental concerns playing a part, the outboard motors are now using the four stroke engines for the low end machines. These engines also benefit from the unending supply of cooling water. This negates any need for conventional radiators or cooling systems. This lowers the weight and the complexity of the outboard motors.

Motors for big boats too

With the advancement in technology, manufacturers of outboard motors are producing he motors for boats as long as 30 feet. There are many variations of the outboard motors that are also available like the electric outboard motors. They are used in the US for specialized applications such as trolling. Their main advantages are the zero emissions and the quietness with which they operate. Along with electric outboard motors, diesel outboard motors are also available but their weight and cost become extremely prohibitive.

Jet propulsion system

Many of the manufacturers have also designed outboard motors with pump jet propulsion systems. These provide more maneuverability and can operate in really shallow waters. This means that the boat operator need not fear the motors getting stuck in seaweed or hitting the rocks in really shallow waters. These types of motors are normally found on jet-skis and small racing boats.

Outboard motors are extremely popular for the simple reasons that they can be transported anywhere, can be fitted easily to dinghies and have easy controls for even the beginner.
