( Brand: Sears ), ( Manufacturer Part Number: 57113 ), ( Part Type: 5hp Motor Flywheel )
The **Sears Waterwitch "Kissel" 57113 Model 1940 Outboard Motor**, identified by its distinctive **3.5 horsepower** rating and the iconic **flywheel nut, rope pulley, and top assembly**, represents a rare and nostalgic piece of mid-20th-century boating history. This vintage outboard, originally manufactured under the **Kissel brand** and later distributed through Sears, Roebuck & Co., embodies the ingenuity of early marine propulsion, blending simplicity with durability for small watercraft like rowboats, canoes, or dinghies. The **flywheel nut**, a key component of the motor s drive system, is designed to secure the flywheel a critical part that transfers power from the engine to the propeller via a **rope pulley mechanism**, a hallmark of older outboard designs. This pulley system, often made of durable leather or synthetic materials, allowed the motor to be easily adjusted or removed, making maintenance and storage more convenient for the average boater. The **top assembly** of the motor features a classic, utilitarian design with exposed brass or chrome-plated fittings, reflecting the craftsmanship of the era, where functionality was prioritized over modern aesthetics. The **3.5hp rating** suggests it was built for light-duty applications, ideal for calm waters or shallow lakes where power needs were modest.

Whether sought after for its mechanical charm, its role in boating history, or its practicality for vintage watercraft, the Sears Waterwitch Kissel 1940 remains a fascinating artifact of an era when outboard motors were still in their formative years.
### **Pros and Cons of buying a Sears Waterwitch Kissel 57113 (1940 Outboard Motor, 3.5HP, Flywheel Nut, Rope Pulley, Top)**
#### **Pros:**1. **Historical and Collectible Value** The 1940 Kissel outboard is a rare and well-preserved example of early marine engine design, making it a desirable piece for collectors and enthusiasts of vintage machinery.
2. **Functional for Small Boats** Despite its age, a properly maintained 3.5HP outboard can still provide sufficient power for small rowboats, canoes, or dinghies in calm waters.
3. **Nostalgia and Restoration Potential** If you enjoy mechanical restoration, this motor offers a chance to work on a classic piece, learning about early outboard engineering and craftsmanship.
4. **Lower Cost (Compared to Modern Motors)** Since these motors are no longer in production, they are often sold at a fraction of the cost of new or even used modern outboards, making them accessible for budget-conscious buyers.
5. **Unique Aesthetic Appeal** The rope pulley, flywheel nut, and vintage design give it a distinct look that may appeal to those who prefer classic over modern marine engines.
6. **Potential for Customization** Some owners modify or restore these motors to improve performance, which can be a rewarding project for those with mechanical skills.

#### **Cons:**1. **Lack of Modern Reliability** Outboards from the 1940s were not built to the same durability standards as today s engines. Rust, worn bearings, and outdated fuel systems are common issues.
2. **Maintenance Challenges** Finding replacement parts, especially for a 80-year-old motor, can be difficult. Many components may no longer be available, requiring custom fabrication or sourcing from antique dealers.
3. **Fuel and Emissions Concerns** Older engines often run on leaded fuel or require carburetor adjustments, which may not be compatible with modern fuel standards. Some areas have restrictions on using such engines.
4. **Limited Power and Efficiency** A 3.5HP motor is extremely weak by today s standards, making it unsuitable for larger boats, rough water, or any serious fishing or towing.
5. **Safety Risks** The rope pulley system is outdated and poses a tripping hazard. Modern outboards use enclosed drives, reducing injury risks.
6. **High Restoration Costs** If the motor is not in perfect condition, restoring it to working order may cost more than simply buying a used modern outboard.
7. **Legal and Insurance Issues** Some marinas or lakes may prohibit the use of vintage outboards due to emissions or safety concerns. Insurance policies may also exclude coverage for older, high-risk engines.
8. **No Warranty or Support** Unlike new or even used modern motors, there is no manufacturer warranty or technical support available for this model.

### **Conclusion:**Buying the Sears Waterwitch Kissel 57113 (1940, 3.5HP) is a decision that should be based on whether you prioritize **historical value, nostalgia, or restoration potential** over practical functionality. If you are an enthusiast with mechanical skills, patience, and a willingness to invest time and money into restoration, this motor could be a fascinating project. However, if you need a **reliable, low-maintenance engine for regular boating**, a modern or even a well-maintained used outboard would be a far better choice.
### **Recommendation:**- **Buy it if:** You are a collector, a restoration hobbyist, or simply love vintage machinery and are prepared for the challenges of maintaining an antique engine.
- **Do not buy it if:** You need a functional, dependable motor for regular use, cannot commit to restoration work, or are unwilling to deal with the difficulties of sourcing parts and repairs.
For most practical boating needs, a **used 5 15HP modern outboard** (such as a Yamaha, Evinrude, or Johnson) would be a far superior investment in terms of reliability, efficiency, and ease of maintenance. However, if you find this motor in excellent condition and are passionate about preserving automotive history, it could be a unique and rewarding acquisition.
