### **Pros and Cons of Buying a 1968 1978 Chrysler P-324 FP324 (8.5 Pitch, 10 Spline Pin Drive, 20/25 HP) Outboard**

#### **Pros**

1. **Classic Vintage Design** The P-324 is a well-known and respected outboard from the late 1960s and early 1970s, prized by collectors and enthusiasts for its mechanical simplicity and historical significance.

2. **Reliable and Durable** Chrysler outboards of this era were built to last, with solid cast-iron components and straightforward engineering. Many still function well after decades of use with proper maintenance.

3. **Easy to Find Parts** Due to their popularity, replacement parts (such as gaskets, seals, and impellers) are relatively accessible, though some may require sourcing from specialty marine suppliers.

4. **Good for Small Boats** The 20 25 HP range makes it suitable for lightweight fishing boats, runabouts, or small bass boats, where power is sufficient but not excessive.

5. **Lower Cost of Ownership (Compared to Modern Outboards)** Fuel efficiency is decent for its time, and repairs are often cheaper than those for modern outboards, though labor costs may still apply.

6. **Nostalgia Factor** If you appreciate classic marine engines, the P-324 has a strong following among vintage boat owners, which can enhance its appeal.

7. **Simpler Maintenance** Unlike modern fuel-injected outboards, these carbureted engines are easier to tune and repair with basic mechanical skills.

#### **Cons**

1. **Age and Wear** Any 1968 1978 outboard will have significant mileage, and internal components like the lower unit seals, impeller, and clutch may be worn out. Expect major rebuilds if the engine is not already restored.

2. **Fuel and Emissions Issues** These engines run on leaded fuel (if available) or modern unleaded fuel, which can cause carbon buildup and poor performance. Some may require modifications to run on modern fuel.

3. **Rust and Corrosion** Older outboards are prone to rust, especially in the lower unit and steering components. A thorough inspection is critical before purchase.

4. **Limited Power for Modern Use** At 20 25 HP, this outboard is underpowered for larger or heavily loaded boats. It may struggle with planing or towing in rough conditions.

5. **No Electronic Ignition** Early Chrysler outboards used points-based ignition systems, which are less reliable than modern electronic ignition. Rebuilding the distributor may be necessary.

6. **Hard to Find Trained Mechanics** While parts exist, finding a mechanic experienced with vintage Chrysler outboards can be difficult, especially outside marine hubs.

7. **Environmental and Legal Concerns** Some areas have restrictions on older outboards due to emissions or noise. Check local regulations before purchasing.

8. **Potential for Hidden Damage** Without a professional inspection, issues like cracked cases, seized bearings, or failed seals may not be immediately obvious.

### **Conclusion and Recommendation**

The **Chrysler P-324 FP324 (1968 1978)** is a **great choice for collectors, restorers, or those seeking a simple, low-power outboard for a small vintage boat**. If you plan to restore it to working condition and enjoy the challenge of maintaining a classic engine, this outboard can be a rewarding purchase. However, if you need a **reliable, high-performance outboard for daily use**, a modern or mid-century (e.g., 1980s 1990s) replacement would be a better investment.

- **Buy if:** You are a collector, enjoy mechanical projects, or need a low-power outboard for a small, lightly used boat. Ensure the engine is either already restored or has a recent rebuild.

- **Avoid if:** You want a hassle-free, high-performance outboard for serious boating. Consider a **Mercury 15 25 HP (1970s), Johnson 20 25 HP, or a modern 20 HP outboard** for better reliability and performance.

- **Inspection is Critical:** Always have a **marine mechanic or experienced vintage outboard specialist** inspect the unit before purchasing. Look for:

- No internal rust or seized components.

- Intact lower unit seals and steering cables.

- A clean, properly adjusted carburetor.

- No excessive play in the drive shaft or clutch.

If you proceed with caution and invest in restoration, the P-324 can be a **fun and functional addition to a classic boat**. Otherwise, modern alternatives may offer better long-term value.
