Review LABWORK Trim Relay Yamaha 50-90hp Outboard fits F150 F250 2005–2009

The **LabWork LAW20556 Relay** is a precision-engineered, high-performance replacement relay designed exclusively for Yamaha marine outboard engines from the **2005 to 2009 model years**, specifically tailored to fit the **F150 and F250 series** with power outputs ranging from **50 to 90 horsepower**. This relay serves as a critical component in the engine s electrical system, ensuring seamless communication between the engine control module (ECM) and various electrical actuators, including the fuel pump, throttle control, and ignition system. Crafted from high-grade, corrosion-resistant materials, the LAW20556 is built to withstand the harsh marine environment, where saltwater, humidity, and constant vibration can degrade standard automotive-grade relays. Its robust construction features **gold-plated contacts** for superior conductivity and longevity, minimizing electrical resistance and preventing oxidation common issues that can lead to intermittent power loss or complete system failure. The relay s compact yet durable housing is designed to fit snugly within the engine bay s tight spaces, ensuring a secure and interference-free installation. Whether replacing a failed original equipment relay or upgrading for enhanced reliability, this LabWork component delivers **OEM-level performance** with added durability, making it an ideal choice for both professional marine technicians and DIY enthusiasts. With its **direct compatibility** and **proven track record** in Yamaha outboards, the LAW20556 relay ensures smooth operation, reduced electrical gremlins, and extended engine life keeping your F150 or F250 running at peak efficiency for years to come.

### **Pros and Cons of buying a Labworks Law20556 Relay for 2005 2009 Yamaha F150/F250 (50 90 HP) Outboards (Part #63P819500000)**

#### **Pros:**

1. **Compatibility** The Law20556 relay is designed specifically for Yamaha F150/F250 outboards from 2005 2009, ensuring a proper fit without modification. This reduces the risk of electrical issues caused by improper wiring or voltage drops.

2. **Improved Electrical Reliability** These outboards, especially in the 50 90 HP range, can experience voltage fluctuations when running multiple accessories (lights, fish finders, trolling motors, etc.). A dedicated relay helps stabilize power delivery, preventing flickering lights, stalling, or electrical component failure.

3. **Prevents Overloading** The relay acts as a protective switch, reducing the strain on the starter motor and alternator by managing high current draws. This can extend the lifespan of the outboard s electrical system.

4. **Easy Installation** Labworks relays are designed for straightforward installation, often requiring minimal wiring adjustments. Many are plug-and-play solutions that can be installed without professional help.

5. **Cost-Effective Upgrade** Compared to full electrical system overhauls or replacing a failing starter or alternator, a relay is a low-cost solution that can prevent more expensive repairs down the line.

6. **Compatibility with Aftermarket Mods** If you ve added accessories like bilge pumps, live wells, or additional lighting, the relay helps ensure these systems run smoothly without overloading the outboard s electrical circuit.

7. **Warranty Coverage** Labworks products often come with warranties, providing peace of mind in case of manufacturing defects or premature failure.

#### **Cons:**

1. **Limited Lifespan** Relays, like any mechanical/electrical component, can wear out over time, especially if exposed to moisture, vibration, or extreme temperatures. A poorly sealed relay may fail prematurely.

2. **Potential for Misapplication** While this relay is designed for the specified Yamaha models, improper installation (e.g., incorrect wiring, loose connections) can render it ineffective or even damage the outboard s electrical system.

3. **Not a Cure for All Electrical Issues** If the outboard s alternator is weak, the battery is dead, or there are corroded connections elsewhere in the system, the relay alone won t fix these problems. A full electrical diagnostic may still be needed.

4. **Cost Relative to Other Solutions** While affordable, some boaters may opt for a more robust solution, such as upgrading the alternator or battery, if electrical problems persist. The relay is a stopgap rather than a permanent fix.

5. **Dependence on Proper Maintenance** The relay must be inspected periodically for corrosion, loose terminals, or signs of overheating. Neglecting maintenance could lead to failure.

6. **May Not Solve All Voltage Drop Issues** If the outboard s wiring is undersized or the battery is too weak, the relay can only do so much. In such cases, upgrading the battery or wiring may be necessary.

### **Conclusion:**

The **Labworks Law20556 relay is a practical and cost-effective solution** for Yamaha F150/F250 outboards (2005 2009) experiencing electrical reliability issues, particularly with high accessory loads. It provides a simple, low-risk upgrade that can prevent more serious problems like starter failure, voltage sag, or component burnout. However, it is not a universal fix it works best when paired with a properly maintained electrical system.

If your outboard is running into **flickering lights, slow cranking, or accessory failures**, the relay is a strong first step. But if the issues persist after installation, further diagnostics (e.g., checking the alternator, battery, or wiring) may be necessary.

---

### **Recommendation:** - **Buy the relay if:**

- You re experiencing **intermittent electrical issues** (e.g., lights flickering, slow starter response).

- You frequently run **multiple high-drain accessories** (fish finders, trolling motors, etc.).

- You want a **simple, low-cost upgrade** before considering more expensive electrical work.

- You re comfortable with a **basic wiring installation** (follow Labworks instructions carefully).

- **Consider alternatives if:**

- The outboard has **consistent electrical failures** (e.g., starter won t engage at all, battery drains rapidly).

- The **alternator or battery is failing** these may need replacement alongside the relay.

- You re unsure about **proper installation** consult a marine electrician if wiring is unfamiliar.

**Final Verdict:** The Law20556 relay is a **smart, preventative purchase** for Yamaha F150/F250 owners dealing with electrical reliability concerns. It s not a permanent fix but a **proactive step** that can save money and frustration in the long run. Always ensure the relay is installed correctly and inspect it periodically for optimal performance.
