Mercury F115 ELPT EFI
Mercury F115 is one of the most popular 115-hp four-stroke engines on the market. The 2.1-liter four-cylinder EFI engine delivers strong torque and excellent acceleration. Its large displacement makes the F115 particularly powerful when carrying a load or on heavier hull models.
It weighs only 163–165 kg, making it one of the lightest 115 hp engines in its class. The engine is quiet, balanced, and highly fuel-efficient. The 35 A charging capacity is more than sufficient for the electronics, and the electric trim/tilt makes handling easy.
Mercury F115 ELPT EFI is one of the most popular 115-horsepower four-stroke engines, and for good reason: it combines a large 2.1-liter displacement, lightweight construction, and quiet operation into an exceptionally well-balanced package. The engine’s large displacement delivers strong low-end torque even at low RPMs, resulting in quick planing and smooth acceleration even when the boat is loaded with passengers or gear.
The EFI fuel injection system precisely optimizes fuel delivery in all conditions, improving start-up, reducing fuel consumption, and making the engine’s performance highly predictable. The F115 is particularly known for its quiet operation—Mercury has focused on intake silencing, engine cowling acoustic treatment, and vibration damping, making the engine pleasant to use even on long trips.
The engine weighs only 163–165 kg, making it one of the lightest 115 hp engines in its class. The lightweight transom design improves the boat’s balance and reduces transom dive when launching. This is particularly important in fishing and recreational boats, where the stern often carries a heavy load.
Mercury’s Power Trim & Tilt offers a wide range of adjustment, making it easier to control the boat in rough water and optimizing fuel efficiency at cruising speeds. The engine also features a powerful 35 A alternator, which is more than sufficient for fishfinders, bow thrusters, and other electronics. Electric start, reliable engine control, and easy freshwater flushing make the F115 a low-maintenance and user-friendly package.
Overall, the Mercury F115 ELPT EFI is an excellent choice for 5–6.5-meter boats where you want to combine strong torque, fuel efficiency, and quiet operation—without unnecessary weight at the stern.
