Choosing between the 2023 Mercury 80 FourStroke and the 2024 Mercury 75 SeaPro comes down to your specific boating needs and priorities.

The 2023 Mercury 80 FourStroke (2023) is a 80hp 4-stroke outboard from Mercury, weighing 140 kg (309 lbs). Its electronic fuel injection delivers reliable starts and improved fuel economy compared to carbureted alternatives. Power trim and tilt makes it easy to adjust on the water.

The 2024 Mercury 75 SeaPro offers 75hp with 4-stroke technology, tipping the scales at 134 kg (295 lbs). Its more compact 1,028 cc displacement keeps weight down while maintaining efficiency.

At 134 kg (295 lbs), the 2024 Mercury 75 SeaPro is the lighter option — an important consideration for smaller boats, portability, and overall fuel efficiency.
