Which of the following types of engines generally have more power per pound?

Outboard engines are known for having a higher power-to-weight ratio compared to other types of engines. This characteristic makes them particularly advantageous for smaller boats where both power and weight considerations are critical for performance and maneuverability. The design of outboard engines allows for significant horsepower while remaining relatively lightweight, enabling them to efficiently propel boats through the water.

Inboard engines tend to be heavier because they are often integrated into the boat's structure, which can affect their power-to-weight ratio negatively. Stern drives also incorporate components of both inboard and outboard engines, typically making them heavier than fully outboard systems. Hybrid engines, while innovative, don’t consistently match the power-to-weight efficiencies found in outboard engines, as they often prioritize fuel efficiency and emissions reductions over pure power output.

This understanding of engine types and their characteristics is crucial for boaters when choosing the appropriate engine based on their performance needs.
