FUN ON THE RUN THE NEW MERCURY 25 AND 30 HP ELECTRONIC-FUEL-INJECTED FOURSTROKES mercurymarine.com
25 hp EFI 30 hp EFI For too long, boaters have settled for sparse features on their small engines. The new lightweight Mercury 25 and 30 hp EFI FourStrokes offer features typically found only on large outboards plus smooth running, quiet performance and excellent fuel efficiency. Both models are electronically fuel injected – an industry first for the battery-free manual-start EFI FourStroke. The 25 hp model is also the first electronically fuel injected engine of that horsepower in the history of outboards. The 30 hp has dropped 32 lbs. on the engine it replaces, while the 25 hp model is now 18 lbs. lighter with more torque to boot. This reduced weight improves boat balance, handling and performance, and makes them more economical for all your boating activities.
