Inboard motors are installed inside the hull of the boat, offering a lower center of gravity and better weight distribution.

  • Advantages:

    • Greater durability and longer lifespan
    • Quieter operation compared to outboard motors
    • Increased fuel efficiency
  • Examples:

    • Volvo Penta D3

3. Stern Drives (Inboard/Outboard)

Stern drives, also known as inboard/outboard systems, combine features of both inboard and outboard motors. The engine is located inside the boat, and the drive unit is outside.

  • Advantages:

    • Versatile; suitable for both freshwater and saltwater
    • Easier to service than inboard motors
  • Examples:

    • MerCruiser 6.2L

4. Jet Propulsion

Jet propulsion systems use a jet of water expelled from the back of the vessel to propel the boat forward. This type of propulsion is commonly used in personal watercraft and high-performance sports boats.

  • Advantages:

    • No external propeller, increasing safety for swimmers
    • Shallow water operation
    • High-speed capabilities
  • Examples:

    • Yamaha WaveRunner

    • Low ongoing operational costs
  • Examples:

    • Beneteau Oceanis
