Review RCPS New Alternator 5.0 5.7 Engine fits CRUSADER MARINE 1999–2003

The **RCPS 39200 Alternator** is a high-performance, direct-replacement alternator meticulously engineered to meet and exceed the demanding electrical needs of the **5.0L and 5.7L Ford Crusader marine engines** produced between **1999 and 2003**. Designed with precision and built to withstand the harsh marine environment, this alternator delivers reliable, high-output power to ensure your engine runs smoothly, whether you're cruising at full throttle or trolling at low speeds. Crafted from high-quality materials, including a robust **silicon-controlled rectifier (SCR) diode assembly**, this alternator provides superior voltage regulation, minimizing fluctuations that could otherwise stress your electrical system and shorten the lifespan of sensitive components like batteries, wiring, and onboard electronics. The **39200 model** features a **140-ampere output**, which is significantly higher than the stock alternator, ensuring ample charge for modern marine accessories from high-wattage stereo systems and LED lighting to advanced GPS and fish finders without overburdening the alternator or causing voltage sags. Its **sealed ball-bearing construction** enhances durability, reducing friction and wear over time, while the **heavy-duty pulley** ensures smooth operation and prevents premature belt wear. The alternator s **direct bolt-on compatibility** with the original Ford mounting points guarantees a seamless installation, eliminating the need for costly modifications or adapters. Whether you're upgrading for improved performance, replacing a failing alternator, or preparing for extended offshore trips, the **RCPS 39200 Alternator** is a dependable choice that combines **power, longevity, and marine-grade reliability** to keep your Crusader engine s electrical system running at peak efficiency.

### Pros and Cons of Buying an RCPS 39200 Alternator for a 1999 2003 5.0L Ford Crusader Marine (5.7L Engine)

#### **Pros**

1. **Direct Fitment and Compatibility** The RCPS 39200 is specifically designed for Ford s 5.0L (302) and 5.7L (302 marine) engines, including the Crusader marine application. It replaces the stock alternator without requiring major modifications, ensuring a straightforward installation.

2. **Higher Output Capacity** The RCPS 39200 is a high-performance alternator, typically rated around **60 70 amps**, compared to the stock unit (often around 45 50 amps). This provides better charging performance, especially under heavy electrical loads (e.g., running multiple accessories, deep-cycle batteries, or aftermarket audio systems).

3. **Improved Reliability** RCPS alternators are known for their durability, often featuring sealed bearings, high-quality diodes, and robust construction. This reduces the risk of premature failure, which is common with stock alternators in marine applications due to vibration and saltwater exposure.

4. **Better Voltage Regulation** High-quality aftermarket alternators like the RCPS 39200 maintain a more consistent voltage output, preventing overcharging or undercharging of batteries, which extends battery life and protects electrical components.

5. **Compatibility with Marine Modifications** If you ve added aftermarket electronics (e.g., fish finders, GPS, stereo systems, or bilge pumps), a higher-output alternator ensures these systems run reliably without draining the battery or causing voltage drops.

6. **Easier Installation** Since it s a direct replacement, no wiring or mounting bracket changes are typically required beyond removing the old alternator. This saves time and labor compared to custom-fit or non-OEM units.

7. **Warranty Coverage** RCPS offers warranties on their alternators, providing peace of mind against defects in materials or workmanship.

#### **Cons**

1. **Cost** The RCPS 39200 is more expensive than a stock alternator, often **two to three times the price**. For a 1999 2003 Crusader, this may be a significant investment if the stock alternator was still functioning adequately.

2. **Potential Overkill for Light Use** If your boat is used infrequently or only for short trips with minimal electrical loads, the extra amperage may not be necessary. A stock alternator or a mid-range aftermarket unit (e.g., 55 60 amps) could suffice without the premium cost.

3. **Installation Challenges in Tight Spaces** While the RCPS 39200 is a direct fit, some marine applications (especially older models like the Crusader) may have tight clearance around the alternator due to other components (e.g., driveshaft, trim tabs). Careful installation may be required to avoid interference.

4. **Compatibility with Stock Voltage Regulator** Some high-performance alternators require a compatible voltage regulator. While the RCPS 39200 is designed to work with stock regulators, using an incompatible regulator (e.g., from a different brand) could cause issues like overcharging or erratic voltage.

5. **Saltwater Corrosion Risk** Even with a high-quality alternator, prolonged exposure to saltwater can still cause corrosion over time, especially if the alternator isn t properly sealed or maintained. Regular cleaning and protection (e.g., dielectric grease on terminals) are necessary.

6. **Potential for Overcharging** If the alternator is paired with an incompatible voltage regulator or battery, it could overcharge sensitive electronics or lead-acid batteries, reducing their lifespan.

### **Conclusion**

The **RCPS 39200 alternator is a strong choice** for a 1999 2003 5.0L/5.7L Crusader marine engine if you prioritize reliability, higher electrical output, and long-term performance. It s particularly beneficial for boats with heavy electrical loads, frequent use, or aftermarket modifications. However, if your usage is minimal and the stock alternator is still functional, the cost may not justify the upgrade.

For most **heavily used or modified Crusader boats**, the RCPS 39200 is a worthwhile investment. If you re unsure, consider a **mid-range aftermarket alternator (e.g., 55 60 amps)** as a cost-effective alternative that still offers significant improvements over the stock unit.

### **Recommendation**

- You frequently run multiple accessories (e.g., fish finder, stereo, bilge pump).

- Your stock alternator is failing or struggling to keep up with electrical demands.

- You want a high-reliability, long-lasting alternator with minimal maintenance.

- You ve added aftermarket electronics that require stable charging.

- Your boat is used sporadically with minimal electrical loads.

- The stock alternator is still working but showing signs of wear (e.g., slow charging, clicking noises).

- You re on a tight budget and can find a reputable 55 60 amp alternator (e.g., from brands like Deka, Cragar, or Universal) at a lower cost.

**Final Note:** Always pair the alternator with a **compatible voltage regulator** (preferably from the same brand) and ensure proper installation to avoid electrical issues. Regular maintenance (e.g., cleaning terminals, checking belts) will extend the alternator s lifespan.
