• Mercury 4 hp: Featured a built-in 0.3-gallon fuel tank and six trim positions, plus a shallow-water drive.
• Mercury 5 hp: A single-cylinder engine that offered more power, but was still lightweight. It often included both an integrated fuel tank and an external fuel tank connection.
• Mercury 6 hp: A single-cylinder, carbureted engine with a larger 123cc displacement (on many models) than the 5 hp, providing slightly more power. 

• Mercury 8 hp: An 84-pound, twin-cylinder engine that offered CDI ignition with electronic spark advance and a multifunction tiller handle.
• Mercury 9.9 hp: A slightly more powerful, two-cylinder version of the 8 hp. Early four-stroke models in this range were carbureted, while later versions (post-2005) received EFI.
• Mercury 15 hp: The most powerful of the portable line, this two-cylinder engine was also available in carbureted versions and later featured EFI for better starting and performance. 

• Quiet, smoke-free operation.
• CARB three-star, ultra-low emissions ratings (on later models).
• Electronic CD ignition for easy starts. 

• Transition to four-stroke: During this period, Mercury phased out most of its two-stroke portable engines and transitioned to the more fuel-efficient and environmentally friendly four-stroke technology.
• Improved features: Later models saw refinements in design for easier carrying, better fuel efficiency, and cleaner emissions.
• Propeller options: The larger 8–15 hp models often offered different propellers to optimize performance for either speed or thrust.
• EFI Introduction: After 2005, Mercury began to offer EFI on many of its small four-stroke models, starting with the 9.9 hp and 15 hp versions.
