However, the premium price may not suit budget-conscious buyers. Some saltwater users have noted corrosion on exposed parts, so regular rinsing is recommended. If you prioritize smooth operation and fuel savings, this is an excellent choice, but if you need a motor for heavy commercial use or extreme saltwater conditions, you might consider a model with better corrosion protection.
- EFI system ensures smooth starting and excellent fuel economy
- Lightweight at 233 lbs for easy handling
- Tiller handle with push-button shift and stop switch
Pros: Smooth and quiet operation; Good fuel efficiency compared to carbureted models; Reliable cold starts
Cons: Higher initial price than some competitors; Some owners report minor corrosion issues in saltwater use
2. Yamaha F40 LA Tiller: Best Durability
The Yamaha F40 LA Tiller is built to last, featuring Yamaha’s advanced corrosion protection and a high-thrust gearcase. In our evaluation, this motor stands out for its durability in saltwater environments. Owner feedback consistently praises its longevity and reliability. The EFI system delivers smooth power, and the high-thrust gearcase provides strong acceleration for heavier boats.
The main drawback is its weight, which can make manual tilting more challenging. Some users find the tiller handle placement less intuitive than Mercury’s design. If you operate in saltwater or need a motor that will hold up over many seasons, the Yamaha is a top contender. However, if weight is a critical factor, you might prefer a lighter model.
- High-thrust gearcase for better hole shot and planing
- Yamaha's corrosion protection system for saltwater use
- Tiller handle with trim and tilt switch
Pros: Excellent corrosion resistance; Strong low-end torque; Reliable and long-lasting
Cons: Heavier than some competitors at 257 lbs; Tiller handle can be awkward for some users
3. Suzuki DF40A Tiller: Best Value
The Suzuki DF40A Tiller offers excellent value without sacrificing performance. Its large displacement engine provides robust torque, and the lean burn technology helps save fuel. Based on owner feedback, this motor is very reliable and runs smoothly. The tiller handle is functional, though not as refined as some competitors.
One downside is that Suzuki outboards are less widely distributed, so finding parts or service may be harder in some areas. Also, a few owners have noted vibration at idle, which can be annoying. If you want a well-priced, efficient motor and don’t mind potentially limited dealer support, the Suzuki is a strong choice.
- Large displacement for strong torque
- Lean burn technology for fuel efficiency
- Tiller handle with gear shift and stop switch
Pros: Great fuel economy; Smooth and quiet operation; Competitive pricing
Cons: Not as common as Mercury or Yamaha, parts availability may vary; Some owners report vibration at idle
4. Tohatsu MFS40A Tiller: Lightest Option
The Tohatsu MFS40A Tiller is the lightest 40 HP outboard we researched, making it ideal for smaller boats or frequent trailering. Its two-cylinder design is simple and lightweight, and the EFI system provides decent fuel efficiency. Owner feedback highlights its easy handling and good value for the price.
However, the two-cylinder engine has less low-end torque than three-cylinder models, so planing heavier loads may be slower. Some owners also mention cold-start issues. If weight is your primary concern and you don’t need maximum power, this is a great option. But if you often carry heavy loads or fish in cold climates, consider a three-cylinder motor.
- Weighs only 218 lbs, lightest in class
- Single overhead cam design for simplicity
- Tiller handle with throttle friction adjustment
Pros: Very light, easy to transport and tilt; Good fuel economy; Affordable price
Cons: Less torque than 3-cylinder competitors; Some owners report harder starting in cold weather
5. Honda BF40 Tiller: Quietest Runner
The Honda BF40 Tiller is known for its whisper-quiet operation, making it a favorite among anglers who value a peaceful ride. In our evaluation, the motor runs very smoothly with minimal vibration. The dual long-troll throttle allows precise speed control for trolling. Owner feedback often praises its reliability and build quality.
However, the Honda comes at a premium price, and parts can be costly. It is also heavier than some alternatives. If noise reduction is your top priority and you have a larger budget, the Honda is excellent. But if you are looking for the best value or need a lighter motor, other options may suit you better.
- Honda's advanced noise reduction technology
- Dual long-troll throttle for trolling
- Tiller handle with stop/start button
Pros: Exceptionally quiet operation; Smooth and refined power delivery; Good fuel economy
Cons: Heavier at 248 lbs; Higher price and more expensive parts
6. Evinrude E-TEC 40 HP Tiller: Best Two-Stroke Option
The Evinrude E-TEC 40 HP Tiller is a modern two-stroke that offers strong performance and lightweight design. Its direct injection system reduces oil consumption and emissions compared to older two-strokes. Based on owner feedback, this motor provides quick acceleration and is popular for bass boats and skiffs.
However, it is still louder and has more exhaust smell than four-stroke competitors. Fuel economy is also worse. Additionally, parts availability has become more limited since Evinrude’s parent company ceased production. If you prioritize raw power and low weight and don’t mind the noise, this is a viable choice. But for most buyers, a four-stroke will be more practical and quieter.
- Direct injection for better fuel economy than traditional 2-strokes
- Lightweight at 225 lbs
- Tiller handle with trim and tilt
Pros: Excellent acceleration and power-to-weight ratio; No oil mixing, easy maintenance; Good for planing heavy loads
Cons: Noisier and smellier than 4-strokes; Less fuel efficient than modern 4-strokes
7. Parsun 40 HP Tiller: Budget Pick
The Parsun 40 HP Tiller is the most budget-friendly option we evaluated. It is a traditional two-stroke carbureted motor, which makes it simple and easy to work on. Owner feedback indicates it provides adequate power for smaller boats at a fraction of the cost of major brands.
However, it comes with significant trade-offs. It is loud, emits smoke, and consumes more fuel. Durability is a concern, with reports of corrosion and reliability issues, especially in saltwater. This motor is best for occasional freshwater use on a tight budget. If you plan to use it frequently or in saltwater, investing in a more reliable four-stroke is strongly recommended.
- Carbureted two-stroke for simplicity

Cons: Noisy, smoky, and less fuel efficient; Durability concerns, especially in saltwater
Frequently Asked Questions
What is the difference between a tiller and a remote outboard?
A tiller outboard has a handle attached directly to the motor that controls steering and throttle, while a remote outboard uses a separate helm and control box. Tiller models are simpler, lighter, and ideal for small boats where space is limited. They are easier to install and allow the operator to sit in the back of the boat, but they can be less convenient for larger boats or when precise control is needed.
Is a four-stroke or two-stroke 40 HP tiller better?
Four-stroke outboards are generally quieter, more fuel-efficient, and produce fewer emissions. They also require less frequent maintenance (no oil mixing). Two-stroke outboards are lighter, have better acceleration, and are simpler to repair, but they are noisier, smellier, and less fuel efficient. For most users, a four-stroke is the better choice unless weight or budget is a major concern.
Can a 40 HP tiller outboard push a pontoon boat?
A 40 HP tiller outboard can push a small pontoon boat (up to about 20 feet) at moderate speeds, but it will not be fast. For larger pontoons, a higher horsepower is recommended. Tiller controls work fine on pontoons, but some owners prefer remote steering for better control and comfort.
What maintenance is required for a 40 HP tiller outboard?
Routine maintenance includes changing the engine oil and filter (for four-strokes), replacing the gearcase oil, inspecting and replacing the water pump impeller annually, checking spark plugs, and flushing the motor with fresh water after saltwater use. Always follow the manufacturer’s recommended service schedule.
How do I choose between different brands of 40 HP tiller outboards?
Consider your priorities: reliability and dealer network (Yamaha, Mercury), fuel efficiency and smoothness (Suzuki, Honda), weight (Tohatsu), or budget (Parsun). Read owner reviews and check parts availability in your area. If possible, test the tiller handle ergonomics before buying, as comfort varies by brand.
