The driveshaft features a **7/6-inch shaft diameter**, a standard size that ensures compatibility with a wide range of compatible Evinrude models, making it a versatile upgrade or replacement option for boaters seeking enhanced durability and performance. Whether used in fishing boats, personal watercraft, or small recreational vessels, this driveshaft provides a smooth, responsive power delivery, allowing operators to navigate with confidence while maximizing fuel efficiency. Its straightforward installation thanks to the pre-machined splines and precise alignment makes it an ideal choice for both DIY enthusiasts and professional mechanics. With its blend of strength, reliability, and compatibility, the Johnson 0387606 driveshaft is an essential component for maintaining peak performance in any Evinrude 9.9 HP outboard application.

### **Pros and Cons of buying a Johnson/Evinrude 9.9 HP 15 HP Standard Driveshaft Outboard Motor (Part #0387606)**

1. **Reliable Brand** Johnson/Evinrude is a well-established manufacturer known for durable and dependable outboard motors, especially in the 2 15 HP range, which is ideal for small boats, canoes, kayaks, and trolling applications.

2. **Lightweight and Compact** The 9.9 15 HP range is designed for small vessels, making it easy to handle, store, and transport. This motor is well-suited for fishing boats, paddle boats, or personal watercraft where weight is a concern.

3. **Fuel Efficiency** Smaller outboards like this typically consume less fuel than larger engines, making them cost-effective for occasional or light-duty use.

4. **Low Maintenance** Compared to larger outboards, these motors have fewer moving parts, reducing the likelihood of major mechanical failures. Routine maintenance (oil changes, spark plug checks) is straightforward.

- Trolling (with proper prop selection)

- Small fishing boats

- Kayaks and canoes (with appropriate adapters)

- Paddle boats and rowboats

- Inflatable boats (with proper mounting)

6. **Affordable Replacement Parts** Since this is a common model, replacement parts (spark plugs, gaskets, carburetor components) are widely available and reasonably priced.

7. **Quiet Operation** Smaller outboards tend to run more quietly than larger engines, which is beneficial for stealth fishing or recreational use in noise-sensitive areas.

8. **Easy to Install** Designed for simple mounting on small boats, often requiring minimal tools and no professional installation.

9. **Long Lifespan with Proper Care** Many of these motors last decades with regular maintenance, especially if used in freshwater.

10. **Compatibility with Older Boats** If you have an older boat without a transom bracket, this motor can often be adapted with aftermarket mounts.

---

1. **Limited Power for Larger Boats** At 9.9 15 HP, this motor is **not suitable** for boats over 12 15 feet or for heavy loads (e.g., deep-V hulls, multiple passengers, or towing). It may struggle in rough water or with strong currents.

2. **No Electric Start (Standard Model)** The **0387606** is a **standard pull-start** model. If you prefer electric start, you ll need to either:

- Buy a different model (e.g., a 2-stroke or 4-stroke with electric start)

- Install an aftermarket electric start kit (which adds complexity and cost)

- Accept the inconvenience of manual starting.

- Are **less fuel-efficient** than modern 4-strokes.

- Produce **more emissions** (though this is less of an issue in freshwater).

- Require **more frequent oil mixing** (if using 2-stroke fuel).

- May have **higher maintenance** (e.g., more frequent spark plug changes, piston ring wear).

4. **Potential for Carbon Buildup** 2-stroke engines are prone to **carbon fouling** if not maintained properly, which can reduce performance over time.

5. **Limited Throttle Response** Smaller outboards may not accelerate as quickly as larger engines, which could be frustrating for some users.

6. **No Built-in Trim/Rudder (Standard Model)** The **0387606** is a **standard driveshaft model** without an integrated trim system. If you need adjustable trim (for better handling), you ll need to:

- Buy a **trim-enabled model** (e.g., a 4-stroke with remote trim).

- Install an aftermarket trim system (additional cost and complexity).

- Accept that the boat may not handle as well in waves or at high speeds.

7. **Fuel and Oil Mixing Required (2-Stroke)** Unlike 4-stroke engines, 2-strokes require **pre-mixed fuel (gas oil)**, which can be messy and less convenient.

8. **Resale Value Depreciation** Older 2-stroke outboards (especially without electric start) may depreciate faster than newer 4-stroke models.

9. **Limited Warranty (If Applicable)** Since this is a used or older model, the original warranty may have expired. Newer models often come with **better warranties** (e.g., 3 5 years on 4-stroke engines).

10. **Potential for Rust or Wear** If the motor has been stored improperly (e.g., in saltwater without flushing), it may have **rust or internal wear**, reducing its lifespan.

---

### **Key Considerations Before Purchase**

1. **Boat Compatibility** Ensure your boat s weight, size, and hull type match the motor s power. A 15 HP motor is **not** for large boats or heavy loads.

2. **Fuel Type Preference** Decide if you want a **2-stroke (gas oil mix)** or a **4-stroke (just gas)**. 4-strokes are cleaner and more efficient but cost more upfront.

3. **Start Mechanism** If you dislike pull-starting, look for a **4-stroke model with electric start** (e.g., Mercury 4.6 HP or Yamaha 6 HP).

- Buy a **trim-enabled model** (e.g., Evinrude 4-stroke with remote trim).

- Install an aftermarket trim system (e.g., **Evinrude Trim Kit**).

5. **Saltwater vs. Freshwater** If using in **saltwater**, ensure the motor is **flushed thoroughly** after each use to prevent corrosion.

6. **Maintenance Commitment** 2-stroke engines require **more frequent maintenance** (oil changes, spark plugs, carburetor cleaning) than 4-strokes.

- **New spark plugs**

- **Carburetor rebuild**

- **Propeller upgrade** (for better performance)

- **Mounting hardware** (if the transom bracket is missing)

---

### **Conclusion & Recommendation**

- **Occasional use** (e.g., weekend fishing, canoe/kayak paddling, small paddle boats).

- **Budget-conscious buyers** who prioritize affordability over modern features.

- **Boats under 12 feet** with light loads (no heavy passengers or towing).

- **Those who don t mind pull-starting** and are okay with 2-stroke maintenance.

- **Frequent or heavy-duty use** (e.g., daily fishing, large boats, rough water).

- **Users who want electric start or 4-stroke reliability.**

- **Boats requiring trim adjustment** (unless you install an aftermarket system).

- **Those who dislike mixing fuel and oil** (2-stroke requirement).

- **If you need a reliable, low-cost motor for a small boat and don t mind 2-stroke maintenance**, the **Johnson/Evinrude 9.9 15 HP standard driveshaft (0387606)** is a **solid used option**, especially if well-maintained.

- Easier maintenance (no fuel/oil mixing).

- Better fuel efficiency.

- Electric start availability.

- Longer lifespan and lower emissions.

- **Rust** (especially in saltwater models).

- **Spark plug condition** (should be clean, not fouled).

- **Carburetor cleanliness** (no clogs or carbon buildup).

- **Driveshaft and propeller** for wear or damage.

- **If your boat lacks a transom bracket**, ensure you have the proper mounting hardware before purchase.

The **Johnson/Evinrude 0387606** is a **decent used option for small, light-duty boats** where cost is a priority and you accept the limitations of a 2-stroke pull-start motor. However, **if budget allows, upgrading to a modern 4-stroke with electric start will provide better long-term reliability and ease of use**. Always match the motor to your boat s needs don t overpower it.
