### **Pros and Cons of buying a Arctic Cat 3639-966 Electric Start Kit for a 2005 Sabercat 500**

#### **Pros**

1. **Convenience and Ease of Use** The electric start kit eliminates the need for manual recoil pulls, making starting the engine effortless, especially in cold weather or after long periods of inactivity. This is particularly useful for riders who may not have the strength or patience for traditional pull-start mechanisms.

2. **Reduced Engine Wear** Frequent manual pull-starts can strain the starter motor and engine components over time. An electric start system reduces this wear, potentially extending the life of the engine and related parts.

3. **Improved Reliability in Harsh Conditions** Cold temperatures can make pull-starting difficult or impossible, especially for older or less powerful engines. The electric start kit ensures the engine starts more reliably in freezing conditions, improving usability in winter or high-altitude environments.

4. **Enhanced User Experience** For riders who prioritize comfort and convenience, an electric start system provides a more modern and user-friendly experience, similar to what is found in larger snowmobiles or ATVs.

5. **Compatibility with Existing Systems** The Arctic Cat 3639-966 kit is designed specifically for the Sabercat 500, ensuring a proper fit and integration with the existing electrical and ignition systems. This reduces the risk of compatibility issues that might arise with aftermarket parts from other brands.

6. **Potential Resale Value Boost** Adding an electric start kit to an older model like the 2005 Sabercat 500 could make it more appealing to buyers who prefer modern conveniences, potentially increasing its resale value compared to a manual-start-only machine.

7. **Easier Maintenance and Storage** Since the engine doesn t need to be manually cranked to start, it may be easier to store the snowmobile for extended periods without worrying about the starter motor seizing up from disuse.

#### **Cons**

1. **Cost** The Arctic Cat electric start kit is not a cheap upgrade. Depending on labor costs if professional installation is required, the total expense could range from **$300 to $600 or more**, which may be a significant investment for an older snowmobile. This cost must be weighed against the machine s overall value and condition.

2. **Battery Dependency** The electric start system relies on a battery to function. If the battery is weak, dead, or not properly maintained, the start kit may fail to work. This adds another layer of maintenance and potential downtime if the battery needs replacement or charging.

- **Battery health** (checking voltage, cleaning terminals, replacing if necessary).

- **Starter motor and solenoid** (ensuring they are not corroded or damaged).

- **Wiring and connections** (preventing corrosion or loose connections that could cause intermittent failures).

This means more upkeep compared to a manual-start-only snowmobile.

4. **Potential for Electrical Issues** Older snowmobiles may not have robust electrical systems designed to handle modern electric start components. Poor wiring, corroded connections, or a weak alternator could lead to electrical gremlins, such as the starter not engaging or the battery draining quickly.

5. **Weight Addition** The electric start kit adds weight to the snowmobile, which could slightly reduce fuel efficiency and handling, though the impact is likely minimal for a 500cc machine.

6. **Installation Complexity** While the kit is designed for the Sabercat 500, installation may still require some mechanical or electrical knowledge. If the rider is not comfortable with wiring or engine modifications, hiring a professional could add to the cost.

7. **Limited Longevity of the Kit** Electric start kits are not indestructible. Over time, the starter motor, solenoid, or wiring may wear out and need replacement. The lifespan of these components depends on usage and maintenance, but they are not as durable as the engine itself.

8. **Not a Performance Upgrade** Unlike engine swaps or exhaust modifications, the electric start kit does not improve speed, power, or handling. It is purely a convenience feature, so buyers should not expect performance gains.

---

### **Conclusion**

The Arctic Cat 3639-966 electric start kit is a worthwhile upgrade for a 2005 Sabercat 500 if the primary goal is to enhance usability, especially in cold or challenging conditions. It reduces manual effort, lowers engine strain from pull-starts, and can make the snowmobile more appealing to potential buyers. However, the cost, additional maintenance requirements, and potential electrical issues must be carefully considered.

For riders who frequently use their snowmobile in harsh weather, value convenience, and are willing to invest in maintenance, the electric start kit is a practical choice. For those who rarely ride, prioritize cost savings, or are uncomfortable with added electrical complexity, the benefits may not outweigh the drawbacks.

---

### **Recommendation**

- You frequently ride in cold or difficult conditions where manual pull-starts are inconvenient.

- You are willing to budget for the initial cost and ongoing battery/maintenance upkeep.

- You plan to keep the snowmobile long-term and want to improve its usability and resale value.

- You are comfortable with basic maintenance or are prepared to pay for professional installation and servicing.

- The snowmobile is primarily used occasionally or for short rides where manual start is not a major issue.

- You are on a tight budget and cannot afford the upfront cost or potential future repairs.

- You are not comfortable with electrical systems or lack the time/motivation for additional maintenance.

- The snowmobile is already in poor condition, and the electric start kit would be an unnecessary expense without addressing other mechanical issues first.

- If the cost is prohibitive, consider a **used electric start kit** from a similar model to save money.

- If electrical reliability is a concern, ensure the snowmobile s battery, alternator, and wiring are in good condition before installing the kit.

- If you rarely ride in cold weather, a **manual start kit** (if available) might be a cheaper alternative for reducing pull-start strain.

Ultimately, the decision depends on your riding habits, budget, and willingness to maintain the additional components. For most serious riders who value convenience, the Arctic Cat electric start kit is a solid upgrade.
