1. Mercury 40 HP FourStroke Outboard Motor: Top Pick
In our research Mercury’s 40 HP FourStroke stood out for its balanced power and refined engineering. The motor delivers smooth acceleration and holds up well in demanding conditions, earning top marks for performance and safety.
The primary weakness is its 20 lb weight, which can stress the transom of lightweight jon boats. If you have a very small hull or plan to trailer the motor frequently, consider a lighter option.
- Compact design fits most jon boat transoms
- Fuel efficient for extended outings
- Quiet operation meets EPA standards
Pros: High thrust for quick maneuvers; Reliable brand support
Cons: Higher weight may affect very small hulls
2. Honda BF40 Outboard Motor: Best Value
Honda’s BF40 earned high marks for its refined engine tuning and user‑friendly features. The digital display simplifies troubleshooting and the low‑emission design aligns with modern environmental expectations.
The motor’s price sits above many comparable 40 HP models, which may deter budget‑focused shoppers. If cost is a primary concern, a more affordable alternative could be a better fit.
- Smooth power delivery for easy handling
- Low emissions meet strict marine standards
- Integrated digital display for diagnostics
Pros: Smooth power delivery; Low emissions
Cons: Slightly higher price point
3. Yamaha F40 Outboard Motor: Best for Light Boats
Yamaha’s F40 offers a good mix of power and portability, making it a solid choice for lighter jon boats. The anti‑theft system adds peace of mind, and the motor runs quietly even at higher RPMs.
Owners in remote locations may find dealer support sparse, which can complicate service. If you frequently travel to isolated waterways, consider a brand with broader service coverage.
- Lightweight for easy handling on small jon boats
- Advanced anti-theft technology
- Durable alloy shaft resists corrosion
Pros: Quiet operation; Strong warranty
Cons: Limited dealer network in remote areas
4. Suzuki DF40A Outboard Motor: Best Durability
Suzuki’s DF40A shines in durability tests, with a protective coating that resists saltwater corrosion. The motor provides a broad power band, allowing both low‑speed cruising and higher‑speed bursts.
The 21 lb weight can be challenging for smaller jon boats, potentially requiring reinforcement of the transom. Boaters with larger hulls will benefit most from this rugged design.
- Corrosion resistant coating for harsh environments
- Wide power band for versatile speed ranges
- Easy tilt and trim controls
Pros: Robust construction; Good resale value
Cons: Heavier than competitors
5. Tohatsu M40 Outboard Motor: Best Budget
Tohatsu’s M40 offers a budget‑friendly option without sacrificing essential performance. Its straightforward control layout makes it approachable for first‑time outboard owners.
The motor’s fuel consumption is higher than some premium models, which can add up on longer trips. If you prioritize extended range over upfront cost, a more efficient motor may be preferable.
- Affordable entry point for new boat owners
- Simple controls reduce learning curve
- Compact size fits tight transoms
Pros: Cost effective; Easy maintenance
Cons: Lower fuel efficiency compared to premium rivals
6. Evinrude E-TEC 40 Outboard Motor: Best for Legacy Brand
Evinrude’s E-TEC 40 retains the brand’s reputation for delivering punchy power in a lightweight package. The motor’s quick throttle response is appreciated by anglers who need rapid speed changes.
Being a 2‑stroke engine, it produces higher emissions than modern 4‑stroke models, which may limit its use in areas with strict environmental regulations. Boaters concerned about compliance should consider a 4‑stroke alternative.
- High power-to-weight ratio
- Instant throttle response
- Legacy brand reputation for performance
Pros: Strong performance; Lightweight
Cons: 2-stroke emissions higher than 4-stroke counterparts
7. Mercury 25 HP FourStroke Outboard Motor: Best Small Power
The Mercury 25 HP FourStroke is a great match for compact jon boats, offering a gentle power curve and low noise levels that enhance the on‑water experience.
Its modest horsepower limits top speed, making it less suitable for users who need rapid acceleration or plan to tow heavy loads. If high speed is a priority, a larger motor would be a better fit.
- Ideal for small jon boats and tender applications
- Low noise operation for peaceful outings
- Easy start with push‑button ignition
Pros: Great fuel economy; Simple installation
Cons: Limited top speed compared to larger models
Frequently Asked Questions
What horsepower range is recommended for a typical jon boat?
Most jon boats perform well with motors between 25 and 40 horsepower, depending on boat length, load capacity and intended use.
Can I install a 40 HP motor on a 10‑ft jon boat?
Yes, if the boat’s transom is rated for the motor’s weight and torque. Check the manufacturer’s specifications for transom strength before mounting.
Do 4‑stroke outboards require special maintenance?
4‑stroke engines follow standard marine maintenance schedules, including regular oil changes, spark plug checks and fuel filter replacement, but they do not need the oil‑mixing steps required by 2‑stroke models.
How do I determine the correct transom weight capacity?
Consult the boat’s owner manual or manufacturer website for the transom’s maximum load rating. Ensure the combined weight of the motor, fuel and accessories stays below that limit.
Is a 2‑stroke motor legal for use on inland lakes?
Many inland lakes enforce strict emissions rules that restrict 2‑stroke outboards. Verify local regulations before using a 2‑stroke motor to avoid fines.
Our Verdict
Our top pick is the Mercury 40 HP FourStroke Outboard Motor for its overall balance of performance, durability and safety. The runner up is the Honda BF40, offering excellent value and low emissions.
