Choosing between the 2023 Mercury 300 V8 and the 2025 Mercury 300 SeaPro comes down to your specific boating needs and priorities.

The 2023 Mercury 300 V8 (2023) is a 300hp 4-stroke outboard from Mercury, weighing 287 kg (633 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 2025 Mercury 300 SeaPro offers 300hp with 4-stroke technology, tipping the scales at 310 kg (684 lbs). Its more compact 4,044 cc displacement keeps weight down while maintaining efficiency.

At 287 kg (633 lbs), the 2023 Mercury 300 V8 is the lighter option — an important consideration for smaller boats, portability, and overall fuel efficiency.
