### Yamaha Exciter 570 LC (SY18) 1987 Model (Part Number: 82M-14172-13-00)

The Yamaha Exciter 570 LC is a classic outboard motor from the late 1980s, known for its reliability, simplicity, and performance in its era. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

---

### **Pros**

1. **Reliability and Durability**

The Exciter 570 LC was designed for durability, with a robust engine block and mechanical simplicity. Many units from this era, especially Yamaha s, are known to last decades with proper maintenance. The two-stroke design was well-proven for its time, offering strong power-to-weight ratios.

2. **Power and Performance**

The 570 LC delivers **57 horsepower**, which was substantial for its era, making it suitable for medium-sized boats (16 20 feet) and providing good acceleration and top-end speed. The Power Jet (PJ) system (a type of jet drive) offered better maneuverability and reduced risk of propeller damage compared to traditional propellers.

3. **Low Maintenance Requirements**

Two-stroke engines like this one are generally easier to maintain than modern four-strokes, with fewer components to fail. Oil mixing (if using two-stroke oil) and basic tune-ups were straightforward tasks for many boat owners.

4. **Classic Yamaha Build Quality**

Yamaha was (and still is) renowned for its engineering and craftsmanship. The Exciter series was built to last, and many examples from the 1980s remain in service today, especially in recreational or fishing applications.

5. **Jet Drive Advantages**

The Power Jet system eliminated the need for a traditional propeller, reducing the risk of entanglement with debris or marine life. This made it ideal for shallow waters, rocky coastlines, or areas with heavy vegetation.

6. **Affordability**

Used units of this model are often sold at reasonable prices, especially compared to newer outboards. This makes it an attractive option for budget-conscious buyers looking for a reliable power source.

7. **Simplicity for DIYers**

The mechanical design is relatively straightforward, allowing owners with basic mechanical skills to perform repairs or adjustments without specialized tools.

8. **Nostalgia and Collectibility**

For enthusiasts, owning a classic Yamaha from the 1980s can be a point of pride. The Exciter series has a cult following, and well-preserved examples may appreciate in value over time.

---

### **Cons**

1. **Environmental Concerns**

Two-stroke engines like the Exciter 570 LC are notorious for their **higher emissions and oil pollution**. They mix oil directly into the fuel, leading to oil leaks into waterways, which is harmful to marine ecosystems. Many regions have banned or restricted two-stroke outboards due to environmental regulations.

2. **Fuel Inefficiency**

Two-strokes consume fuel at a higher rate than modern four-stroke engines. The Exciter 570 LC has a **5-gallon fuel tank**, but its thirsty nature means it may require frequent refueling, especially on longer trips.

3. **Noise and Vibration**

Classic two-stroke engines are often louder and vibrate more than modern outboards. This can be uncomfortable for passengers and may not meet noise regulations in some areas.

4. **Limited Modern Technology**

- Electronic fuel injection (EFI)

- Digital diagnostics

- Variable trim systems

- Electric start (most 1987 models are manual start)

- Modern corrosion-resistant materials (e.g., aluminum instead of cast iron in some components)

This can make repairs harder if parts are no longer readily available.

5. **Corrosion and Wear**

Being an older model, the Exciter 570 LC may suffer from **corrosion in critical areas** (e.g., exhaust manifolds, lower units, or electrical components). The Power Jet system, while durable, can also accumulate debris over time, requiring occasional cleaning.

6. **Parts Availability**

While Yamaha parts are still available for older models, some components (e.g., specific seals, gaskets, or electrical parts) may be harder to find than in newer engines. Prices for replacement parts can also be higher due to limited production.

7. **Resale Value**

Unlike newer outboards, the Exciter 570 LC does not hold significant resale value. If you plan to upgrade later, the depreciation may not be as favorable as with a modern, fuel-efficient engine.

8. **Regulatory Restrictions**

Some marinas, lakes, or states have **banned or restricted two-stroke engines** due to environmental laws. Before purchasing, check local regulations to ensure compliance.

9. **Performance Limitations**

While 57 horsepower was impressive in the 1980s, it may feel underpowered on larger or heavier boats today. Modern outboards offer more torque and efficiency, which can translate to better handling and fuel savings.

10. **Manual Start Only**

Most 1987 Exciter models require a **pull-start**, which can be inconvenient compared to electric start systems in newer engines.

---

### **Conclusion**

The **Yamaha Exciter 570 LC (1987)** is a **reliable, powerful, and durable** outboard that excels in simplicity and performance for its era. It remains a favorite among classic boat enthusiasts, fishermen, and those who appreciate mechanical robustness. However, its **environmental drawbacks, fuel inefficiency, lack of modern features, and potential corrosion issues** make it less ideal for today s standards.

If you are looking for a **budget-friendly, low-maintenance power source for a small to medium boat** and are willing to accept its limitations (e.g., environmental impact, manual start, and parts availability challenges), this engine can be an excellent choice especially for recreational or fishing use in areas where two-stroke restrictions do not apply.

For **daily use, larger boats, or environmentally sensitive areas**, a modern **four-stroke outboard** (e.g., Yamaha s F200, F300 series, or other brands like Mercury or Suzuki) would be a more practical and future-proof investment.

---

### **Recommendation**

- You are restoring or maintaining a **classic boat** and want a proven, high-performance engine.

- You are on a **tight budget** and need a reliable used outboard for occasional use.

- You are in an area with **no two-stroke restrictions** and can properly maintain the engine.

- You enjoy **DIY mechanics** and are comfortable with the challenges of a two-stroke.

- You prioritize **nostalgia or collectibility** over modern convenience.

- You plan to use the boat **frequently or for long hours**, as fuel costs and maintenance may outweigh the savings.

- You are in an area with **strict environmental laws** or marina restrictions on two-stroke engines.

- You want **modern features** like electric start, EFI, or digital diagnostics.

- You are looking for **high resale value** or long-term cost efficiency.

- You are not prepared for **potential corrosion issues** or the need for occasional major repairs.

- If you like the **Power Jet system**, look for a **newer Yamaha 4-stroke jet drive** (e.g., F200 or F300 series) for better efficiency and compliance.

- For a **budget-friendly modern alternative**, consider a **used 4-stroke outboard** (e.g., Yamaha 5.0 or 7.0 HP series) that offers better fuel economy and environmental friendliness.

- If you are restoring a **classic boat**, pair the Exciter with a **modern auxiliary engine** (e.g., a small 4-stroke) for versatility.

Ultimately, the Exciter 570 LC is a **great engine for the right owner** one who values its strengths and can work with its limitations. For most modern applications, however, a newer four-stroke outboard would be the smarter long-term choice.
