Choosing between the 2025 Mercury 40 SeaPro and the 2025 Yamaha F40FEHA comes down to your specific boating needs and priorities.

The 2025 Mercury 40 SeaPro (2025) is a 40hp 4-stroke outboard from Mercury, weighing 92 kg (203 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 Yamaha F40FEHA offers 40hp with 4-stroke technology, tipping the scales at 83 kg (182 lbs). Its more compact 762 cc displacement keeps weight down while maintaining efficiency.

At 83 kg (182 lbs), the 2025 Yamaha F40FEHA is the lighter option — an important consideration for smaller boats, portability, and overall fuel efficiency.

Both motors are solid choices in the 40 HP class. Your final decision should factor in your boat size, typical use conditions, dealer availability in your area, and budget.
