Review HUSQVARNA Clutch Shaft No Era P/n Used Oe fits 250 400 500 1981–2012

The **Husqvarna 16-11-663-01** is a high-performance clutch shaft designed specifically for Husqvarna outboard motors produced between the model years **1981 and 1985**, covering displacement ranges of **250cc, 400cc, and 500cc**. This precision-engineered component is a critical part of the motor s drivetrain, ensuring smooth power transfer from the engine to the propeller while maintaining optimal reliability and durability. Crafted with Husqvarna s signature attention to detail, the clutch shaft is built to withstand the demanding conditions of marine environments, including exposure to saltwater corrosion, vibration, and high-stress operating loads. Its robust construction features a **12-inch length**, carefully calibrated to match the mechanical specifications of the original engine setup, allowing for seamless integration with the clutch assembly, propeller shaft, and transmission components. The shaft is typically made from **high-grade steel**, heat-treated for enhanced strength and resistance to wear, ensuring longevity even under prolonged use. This part is essential for maintaining the motor s performance, as it plays a pivotal role in managing torque and reducing strain on the clutch mechanism, thereby preventing premature failure and extending the lifespan of the entire drivetrain. Whether used in recreational fishing boats, speedboats, or other marine applications from the early 1980s, replacing a worn or damaged clutch shaft with this genuine Husqvarna part guarantees restored functionality and peace of mind, aligning perfectly with the original equipment manufacturer s standards. For optimal results, it is recommended to pair this shaft with compatible clutch components and follow Husqvarna s maintenance guidelines to preserve the motor s efficiency and reliability.

### **Pros and Cons of buying a Husqvarna 16-11-663-01 (250/400/500 Clutch Shaft, 12", 81-85, P/N)**

1. **Original Equipment (OEM) Part** This is a genuine Husqvarna clutch shaft, meaning it is designed to fit perfectly with minimal risk of compatibility issues. It will maintain the original performance and reliability of the chain saw.

2. **High Quality and Durability** Husqvarna is known for manufacturing robust, long-lasting components. The clutch shaft is built to withstand heavy use, reducing the likelihood of premature wear or failure.

3. **Easy Installation** Since it is a direct replacement part, swapping it in should be straightforward, especially if you have basic mechanical skills. No modifications to the chain saw are typically required.

4. **Reliability in Older Models** The 81-85 series chain saws were well-built, and using an OEM part ensures that the clutch shaft will function as intended, reducing the risk of unexpected breakdowns.

5. **Warranty Coverage (if applicable)** If purchased from an authorized dealer or directly from Husqvarna, the part may still be eligible for warranty coverage, providing peace of mind.

6. **Prevents Chain Slippage or Binding** A worn or damaged clutch shaft can cause the chain to slip or bind, leading to poor cutting performance or even accidents. Replacing it ensures smooth operation.

7. **Compatibility with Aftermarket Parts** While this is an OEM part, it is also compatible with many aftermarket clutch assemblies, giving you flexibility if you decide to upgrade later.

---

1. **Cost** As an OEM part, it will likely be more expensive than a generic or aftermarket alternative. Prices can range from $50 to $100 or more, depending on availability and seller.

2. **Limited Availability** Older Husqvarna parts, especially those for discontinued models, can be harder to find. You may need to order from specialty suppliers, eBay, or salvage yards, which could take time.

3. **Potential for Counterfeit Parts** If purchasing from an untrusted source (e.g., random online sellers), there is a risk of receiving a counterfeit or low-quality replica that could fail prematurely.

4. **No Upgrade Benefits** Unlike aftermarket parts, this is a direct replacement and does not offer performance improvements (e.g., lighter weight, better durability, or enhanced clutch engagement).

5. **Maintenance Still Required** Simply replacing the clutch shaft does not eliminate the need for regular maintenance (e.g., chain sharpening, bar oil, and clutch adjustment). Neglecting these can still lead to issues.

6. **Potential for Overkill** If the rest of the chain saw is worn or outdated, replacing just the clutch shaft may not be enough to restore optimal performance. A full rebuild might be more cost-effective in the long run.

The **Husqvarna 16-11-663-01 clutch shaft** is a solid choice if you need a **reliable, OEM replacement** for your 81-85 model chain saw. It ensures proper function, fits seamlessly, and maintains the original performance of your tool. However, the **higher cost and potential availability issues** may make it less appealing compared to aftermarket alternatives if you're willing to take a slight risk for savings.

If your primary goal is **replacing a worn part to restore safety and functionality**, this is the safest option. If you're looking for **cost savings or performance upgrades**, an aftermarket clutch shaft (from reputable brands like **Oregon, Viking, or Husqvarna s own aftermarket line**) might be worth considering just ensure it s compatible and of good quality.

---

- You prioritize **absolute reliability and warranty coverage**.

- You have **limited time** and want a **guaranteed fit**.

- You re unsure about aftermarket quality and want to avoid potential issues.

- You re on a **tighter budget** and can find a **high-quality, compatible replacement** (e.g., Husqvarna s own aftermarket clutch shafts or trusted brands).

- You re comfortable **verifying compatibility** and **researching seller reviews** to avoid counterfeits.

- You plan to **upgrade other components** (e.g., bar, chain, or clutch assembly) soon, making the extra cost of the OEM part less justified.

**Final Verdict:** For most users, the **OEM clutch shaft is the best choice** for peace of mind, especially if the saw is still in regular use. However, if you re open to aftermarket options and can verify quality, you may save money without sacrificing performance. Always **inspect the part upon arrival** and **follow Husqvarna s maintenance guidelines** to extend its lifespan.
