Operating a boat is different from driving a car or riding a bike. While you don't need a driver's license to drive a boat, there are other requirements and rules to follow for legal and safe operation. The person in charge of steering a boat with an engine is called the pilot, and they use the pilot's wheel to control it. The term pilot originates from people capable of controlling and navigating a large ship across bodies of water. There are different types of boat engines, such as outboard, inboard, and stern drive engines, each with unique features and applications. Outboard engines are mounted outside the boat's hull and are used for both power and steering. Inboard engines, on the other hand, are located inside the hull and are connected to a drive shaft that powers the propeller. Stern drive engines, also known as inboard-outboards, combine features of both outboard and inboard engines.
| Characteristics | Values |

| Licence required | No, but a Boater Education Card is required in most states |
| Engine types | Outboard, inboard, stern drive, jet drive |
| Outboard engine characteristics | Mounted on the transom of the boat; used to power and steer the boat |
| Inboard engine characteristics | Located inside the boat's hull; four-stroke automotive engines modified for use on the water; powers a drive shaft connected to a propeller; steered using a rudder controlled by a steering wheel |
| Stern drive engine characteristics | Similar to inboard engines but with a drive unit used to steer the boat |
| Jet drive engine characteristics | Uses water to propel and steer the boat |
What You'll Learn
Outboard Engines
Larger outboard motors, of 100 HP and above, are linked to controls at the helm and are either tiller steered or controlled from the helm. They are affixed to the transom using clamps. These range from 2-, 3-, and 4-cylinder models generating 15 to 135 HP, suitable for hulls up to 17 feet in length, to powerful V6 and V8 cylinder blocks rated up to 627 HP, which can be used on boats 37 feet or longer.

Inboard Engines
There are two main types of inboard engine: direct-drive (D-drive) and V-drive. Direct-drive engines are connected to a shaft that protrudes straight out of the bottom of the boat, with a propeller at the end. This setup minimises power loss and is highly reliable, but it may require the engine to be placed further forward, reducing cabin and seating space. V-drive engines, on the other hand, face forward and use a transmission to redirect the drive shaft towards the back of the boat, creating a V shape. This configuration provides more cabin or seating space but loses some efficiency due to the change in direction.

Stern Drive Engines
The engine of a sterndrive boat is usually a four-stroke automotive engine that has been adapted for marine use. It is mounted inside the boat, just forward of the transom, and is connected to a drive shaft that powers the propeller. The outdrive, which resembles the bottom half of an outboard motor, is composed of two sub-units: an upper unit containing a driveshaft connected to the engine through the transom, and a lower unit containing a vertical driveshaft that transmits power to the propeller shaft. The boat is steered by pivoting the outdrive, and no rudder is required.
When choosing between a sterndrive and an inboard engine, it is important to consider factors such as manoeuvrability, interior space, durability, power, and noise level. Stern drive engines offer improved manoeuvrability and more interior space, while inboard engines are known for their durability, power, and quiet operation. Ultimately, the decision should be based on the specific needs and preferences of the boat owner.

Jet Drive Engines
Jet drives are commonly used in personal watercraft and larger vessels designed for shallow water conditions. They are also used in jet boats, which can have inboard or outboard jet drives. Jet drives are often chosen for their safety, as there is no spinning propeller blade that could potentially injure swimmers.
When choosing a jet drive engine, it is important to consider the specific requirements of your vessel and the conditions in which it will be operated. Jet drives can be an excellent choice for boaters seeking reliable performance, superior thrust, and minimal environmental impact.

Boating Licenses
While a driver's license is not required to drive a boat, there are other requirements and rules to be followed to operate a boat legally and safely. These include age restrictions and boating licenses or safety certificates.
In the United States, each state has its own age restrictions on who can drive a boat. For example, in Texas, you must be at least 13 years old, whereas in Florida, the minimum age is 14. Additionally, some states like New York have implemented laws mandating that all boat operators carry a safe boating certificate or boating safety license. These certificates can be obtained by taking a boating safety course, either in person or online, and are recognized across all states.
The boating safety courses cover basic boating skills and encourage common sense and courtesy on the water. They also provide critical safety information, navigation rules, and etiquette to protect yourself and others while boating. It is important to note that boating privileges can be revoked if you are found to be boating irresponsibly, with offenses including failure to report an accident, boating while intoxicated, and operating the boat recklessly.
Therefore, while a boating license is not the same as a driver's license, it is crucial to follow the relevant regulations and obtain the necessary certifications to ensure safe and legal boating.

Frequently asked questions
No, you don't need a driver's license. However, there are other requirements and rules you need to follow to legally and safely operate a boat. Each state has its own age restrictions, and you will need to pass a boater education course and exam to get your boating license. You will need to carry your Boater Education Card with you while operating your vessel.
The right boat engine type depends on how you will use your boat. There are four common engine and drive types: outboard, inboard, stern drive, and jet drive. Outboard engines are mounted on the transom of the boat and are used to power and steer smaller boats. Inboard engines are located inside the hull and are connected to a shaft that drives the propeller. Stern drives are similar to inboards but have a drive unit/propeller mounted on the transom to steer the boat. Jet drives use a large automotive engine and a water jet to propel and steer the boat.
An outboard motor is mounted on the transom of the boat, outside the hull, and it powers and steers the boat. Inboard motors are located inside the hull and power a drive shaft connected to a propeller. Inboards do not steer the boat; instead, they use a rudder controlled by a steering wheel.
The verb "drive" is not typically used for boats. Instead, you “pilot” a boat if you are the captain and use the pilot's wheel to control it. If you are not the pilot but still control the wheel, you "steer" the boat.
Some signs to look out for include decreased engine power, strange engine noises, engine overheating, and the engine not starting. These issues could be due to problems with the fuel system, dirty spark plugs, clogged raw water intake, a faulty raw water impeller, or a dead battery.
