### Pros and Cons of buying a Mercury 8.0L Command Thrust 20 (38 RH, 75 115 HP)

#### **Pros**

1. **Power and Performance**

The Mercury 8.0L Command Thrust 20 is a high-performance outboard motor designed for speed and handling. With a power range of 75 115 HP, it delivers strong acceleration and top-end speed, making it ideal for sportfishing, wakeboarding, or cruising at higher speeds. The 20-inch propeller is optimized for both power and efficiency, allowing for quick bursts of speed and responsive maneuvering.

2. **Fuel Efficiency and Range**

While not as fuel-efficient as smaller outboards, the 8.0L engine strikes a balance between power and fuel consumption. It is more efficient than larger V8 outboards, meaning it can cover longer distances on a single tank compared to higher-horsepower models. The fuel injection system helps optimize combustion, reducing waste and improving overall efficiency.

3. **Durability and Build Quality**

Mercury is a well-established brand known for robust engineering and durable construction. The Command Thrust 20 is built with marine-grade materials, including corrosion-resistant components and reinforced housings. The 8.0L inline-four engine is designed to handle heavy loads and frequent use, making it suitable for both recreational and semi-professional applications.

4. **Ease of Maintenance**

Mercury outboards are generally easier to maintain than older or less reputable brands. The Command Thrust 20 features accessible components, clear maintenance schedules, and a wide availability of replacement parts. The fuel-injected system also reduces the risk of clogging or carburetor issues common in older outboards.

5. **Versatility**

- **Sportfishing:** The power and speed help cover water quickly, and the 20-inch prop can handle heavier loads.

- **Wakeboarding/Skiing:** The 75 115 HP range provides enough power for towing multiple riders or larger wakeboards.

- **Cruising:** The balance of speed and efficiency makes it suitable for day trips or weekend getaways.

- **Pontoon Boats:** Many owners use this motor on larger pontoons for a mix of speed and stability.

6. **Reliability**

Mercury s reputation for reliability extends to this model. The 8.0L engine is less prone to catastrophic failures compared to smaller or older outboards, especially when properly maintained. The Command Thrust series is known for consistent performance and fewer breakdowns during critical moments.

7. **Resale Value**

Mercury outboards, particularly well-maintained models like the Command Thrust 20, hold their value reasonably well. This means you can recoup a significant portion of your investment if you decide to sell or upgrade later.

8. **Noise and Vibration Reduction**

The 8.0L engine incorporates sound-dampening technologies and vibration isolation, making it quieter and smoother than older outboards. This is beneficial for both the operator s comfort and for minimizing disturbance to others on the water.

9. **Compatibility with Modern Boats**

- **Center console boats** (for fishing or hunting).

- **Bowriders** (for speed and handling).

- **Cuddy cabins** (for cruising comfort).

The 20-inch prop and power range make it a good fit for boats weighing 3,500 5,000 pounds, depending on load.

10. **Aftermarket Support**

There is a strong aftermarket community for Mercury outboards, with aftermarket props, exhaust systems, and performance upgrades available. This allows owners to customize the motor for specific needs, such as increased speed, better fuel efficiency, or reduced noise.

---

#### **Cons**

1. **High Initial Cost**

The Mercury 8.0L Command Thrust 20 is not a budget-friendly outboard. Prices typically range from **$8,000 to $12,000 **, depending on the year, condition, and whether it is new or used. This makes it a significant investment compared to smaller outboards (e.g., 4.6L or 5.0L models) or older brands.

2. **Fuel Consumption**

While more efficient than larger V8 outboards, the 8.0L engine still consumes fuel at a higher rate than smaller engines. On a full tank (typically 18 22 gallons), you can expect **10 15 MPG at cruising speeds**, which adds up over long trips. This can be a drawback for frequent or long-distance use.

3. **Maintenance Costs**

Although Mercury outboards are reliable, maintenance costs can add up over time. Regular servicing, including oil changes, spark plug replacements, and propeller maintenance, is necessary. Additionally, parts like impellers, gaskets, and fuel injectors may need replacement more frequently than in smaller engines. Budget for **$300 $800 annually** for routine maintenance, depending on usage.

4. **Weight and Installation Challenges**

The 8.0L Command Thrust 20 is a heavy motor, weighing around **300 350 pounds**. This requires a sturdy boat with proper transom support. Installing it may require additional hardware (e.g., brackets, reinforcement) to ensure stability, especially on larger or older boats. Improper installation can lead to vibration issues or motor damage.

5. **Noise and Exhaust**

While quieter than older outboards, the 8.0L engine is still louder than smaller, more modern outboards. The exhaust can be noticeable, and some owners report that it is louder at higher RPMs. If noise is a concern (e.g., for early-morning fishing or sensitive areas), this may be a drawback.

6. **Propeller Wear and Damage**

The 20-inch prop is powerful but also more susceptible to damage from debris (e.g., rocks, logs, or docks). Running aground or striking objects can bend or damage the prop, leading to reduced performance or the need for costly replacements. Propellers for this motor can cost **$300 $600** if damaged.

7. **Limited Low-End Torque**

While the 8.0L engine provides strong top-end power, it may struggle with heavy loads at low speeds (e.g., towing a large wakeboarder or fishing in rough conditions). Some owners report that it requires higher RPMs to maintain speed in rough water, which can be tiring over long periods.

8. **Resale Depreciation**

Like most outboards, the Mercury 8.0L Command Thrust 20 will depreciate over time. After 5 7 years, the resale value may drop significantly, especially if the motor has high mileage or lacks maintenance records. This is a consideration if you plan to upgrade later.

9. **Environmental Impact**

The 8.0L engine burns more fuel and produces more emissions than smaller outboards. While it is cleaner than older two-stroke engines, it still contributes to noise and pollution. Some marinas or eco-sensitive areas may have restrictions on larger outboards.

10. **Learning Curve for New Owners**

If you are used to smaller outboards, the 8.0L Command Thrust 20 may feel more complex to operate. The higher power requires more careful handling, especially when accelerating, decelerating, or maneuvering in tight spaces. New owners may need time to adjust to the motor s responsiveness.

---

### **Conclusion**

The Mercury 8.0L Command Thrust 20 (38 RH, 75 115 HP) is a **high-performance, versatile, and reliable outboard** that excels in speed, handling, and durability. It is well-suited for sportfishing, wakeboarding, cruising, and larger boats where power and efficiency are priorities. However, it comes with **higher upfront and maintenance costs**, as well as trade-offs in fuel efficiency and noise compared to smaller engines.

This motor is **ideal for owners who prioritize performance, speed, and the ability to handle heavier loads** without sacrificing too much in terms of reliability. It is less suitable for those on a tight budget, frequent long-distance cruisers, or those who prefer ultra-quiet operation.

---

### **Recommendation**

- You need a **powerful, fast, and responsive outboard** for sportfishing, wakeboarding, or cruising.

- Your boat is **large enough to handle the weight and power** (typically 3,500 pounds, depending on load).

- You are willing to **invest in maintenance and fuel costs** for long-term reliability.

- You want a **well-built, reputable brand** with strong aftermarket support.

- You plan to use the motor **for high-performance activities** where speed and handling matter more than fuel efficiency.

- You are on a **tight budget** smaller outboards (e.g., 4.6L or 5.0L Mercury) offer similar reliability at a lower cost.

- You prioritize **fuel efficiency and low operating costs** a smaller engine (e.g., 4.
