Review MERCURY New Old Stock Foot Plate Assembly fits 1990–1994

The **Mercury 813651A3 plate** from the late 1980s and early 1990s is a highly sought-after aftermarket part for classic Mercury marine engines, specifically designed for the **Mercury 8.0 HP (813651A3) outboard motor** produced between **1990 and 1994**. This particular plate, often referred to as the "throttle body plate" or "intake manifold plate," plays a critical role in the engine s performance and functionality by housing essential components such as the throttle linkage, carburetor connections, and intake passages. Crafted from durable, precision-machined aluminum, the plate ensures a tight seal with the engine s cylinder head and carburetor assembly, preventing leaks while allowing smooth airflow into the combustion chamber. The design of the 813651A3 plate reflects Mercury s engineering standards of the era, featuring drilled and tapped holes for mounting the carburetor, throttle cables, and vacuum lines, all of which are meticulously aligned to optimize fuel delivery and engine response. Over time, wear and tear such as corrosion, warping, or cracked mounting points can compromise the plate s integrity, leading to carburetor misalignment, fuel leaks, or even engine stalling. Restoring or replacing this plate with an authentic OEM or high-quality aftermarket replica ensures that the engine operates at peak efficiency, whether for recreational boating, fishing, or classic car restoration projects. For collectors and enthusiasts, the 813651A3 plate is not just a functional component but also a tangible piece of automotive history, embodying the innovation and craftsmanship of Mercury s mid-1990s outboard lineup.

### **Pros and Cons of Buying a Mercury 813651A3 (1990 1994) with Plate Ending in 1993**

#### **Pros**

1. **Classic Design and Nostalgia** The Mercury 813651A3 is a well-regarded model from the early 1990s, known for its distinctive styling, which appeals to collectors and enthusiasts. Its design is reminiscent of a bygone era, offering a sense of nostalgia for those who appreciate classic American automobiles.

2. **Reliability for Its Era** Mercury vehicles from this period were generally well-built, with solid mechanical foundations. The 813651A3, being part of the mid-1990s lineup, benefited from improvements made over earlier models, such as better fuel injection systems and more refined engines.

3. **Moderate Maintenance Costs** Compared to some older vehicles, this model is not excessively difficult to maintain. Basic repairs like oil changes, brake replacements, and minor electrical fixes are relatively straightforward and affordable, especially if you have access to a mechanic familiar with Ford/Mercury models.

4. **Potential for Customization** The 813651A3 s body style allows for a variety of modifications, from cosmetic upgrades (custom paint, wheels, interior) to performance enhancements (tuning the engine, suspension upgrades). This makes it a good candidate for personalization.

5. **Resale Value for Enthusiasts** While not a high-value collector s car, models from this era with lower mileage and good condition can still hold some appeal among classic car buyers. If maintained well, it may retain a modest resale value.

6. **Fuel Efficiency for Its Time** The 813651A3 typically came with a 3.8L V6 engine, which, while not the most fuel-efficient by modern standards, was reasonably efficient for its era. It offered a balance between power and economy, making it practical for daily driving.

7. **Availability of Parts** Being a Ford/Mercury model, parts are widely available, both new and used. This reduces the risk of long waits or difficulty finding replacement components.

#### **Cons**

1. **Age and Wear** A vehicle from the early 1990s will inevitably show signs of age, including rust (especially in the undercarriage, wheel wells, and frame), worn suspension components, and aging interior materials. Rust can be a significant issue if the car was not properly maintained in snowy or salty climates.

2. **Reliability Concerns Over Time** While the 813651A3 was reliable for its time, some common issues include:

- **Transmission problems** (especially in automatic models, where fluid leaks or solenoid failures can occur).

- **Electrical gremlins** (common in older vehicles, such as faulty wiring, intermittent issues with lights, or dashboard gauges).

- **Engine wear** (timing belt replacement may be due soon, and older engines can develop oil leaks or carbon buildup).

- **Rust-related structural issues** (corrosion can weaken the frame or floor pans, compromising safety).

3. **Higher Maintenance Frequency** Unlike newer cars with extended warranties or modern diagnostics, this model will require more frequent and potentially costly maintenance. Items like brakes, belts, hoses, and fluids will need regular attention.

4. **Insurance Costs** Older cars often come with higher insurance premiums, especially if they are not considered "classic" (which typically requires them to be at least 20 30 years old). Comprehensive coverage may be expensive, and parts may not be fully covered under standard policies.

5. **Driving Experience** Modern vehicles offer superior safety features (airbags, stability control, anti-lock brakes), noise reduction, and comfort. The 813651A3 lacks these advancements, which can make it less safe and less comfortable for long drives or highway use.

6. **Fuel Economy Limitations** While decent for its time, the 813651A3 s fuel efficiency is poor by today s standards. Expect around 15 20 MPG in the city and 25 30 MPG on the highway, which can add up in fuel costs over time.

7. **Depreciation** Classic cars appreciate over time if they are well-maintained, but most everyday vehicles from this era depreciate rapidly. Unless you plan to keep it indefinitely, you may not recoup much of your investment when selling.

8. **Environmental Regulations** Older vehicles may not meet modern emissions standards, which could limit where you can drive it or require modifications to pass inspections in some areas.

### **Conclusion**

The Mercury 813651A3 (1990 1994) is a functional and stylish vehicle with a strong following among classic car enthusiasts. It offers a blend of reliability, customization potential, and nostalgic appeal, making it a viable choice for someone who enjoys working on cars or appreciates vintage aesthetics. However, its age means it will require significant maintenance, may not be as safe or efficient as modern alternatives, and could end up costing more in the long run due to wear and tear.

If you are looking for a **project car** or a **daily driver with character**, this model can be a rewarding purchase if you are prepared for the challenges. If you prioritize **modern safety, fuel efficiency, and low maintenance**, a newer or more modern used vehicle would be a better investment.

---

### **Recommendation**

**Buy the Mercury 813651A3 if:**

- You are an enthusiast who enjoys restoring or modifying classic cars.

- You have the time, budget, and mechanical skills to address its common issues (rust, transmission, electrical problems).

- You plan to keep it for the long term and are okay with higher maintenance costs.

- You find it at a reasonable price (preferably under $3,000 $5,000 for a project car, depending on condition).

**Avoid it if:**

- You need a reliable, low-maintenance daily driver.

- You cannot afford unexpected repairs or storage costs.

- You prioritize modern safety features and fuel efficiency.

- You are not prepared to invest time in maintaining or restoring it.

**Alternative Considerations:**

- If you like the style but want something more modern, look for a **Ford Taurus (1992 1996)** or **Mercury Sable (1990s)**, which are slightly newer and may be more reliable.

- If you want a true classic with better long-term value, consider a **1980s early 1990s Mustang or Thunderbird**, which hold collector appeal.

- For a budget-friendly used car with better reliability, a **Toyota Camry (1990s) or Honda Accord (1990s)** would be a smarter choice.

Ultimately, this Mercury is a **fun but high-maintenance** purchase best suited for those who love the challenge of working with an older vehicle.
