Review OMC JOHNSON EVINRUDE Screw Qty Nos

The **OMC Johnson Evinrude 303247 Screw (Part No. 0303247)** is a precision-engineered, high-performance replacement drive screw designed exclusively for select Evinrude outboard motors, ensuring optimal propulsion and reliability for marine applications. Crafted from durable, corrosion-resistant materials, this screw is built to withstand the harshest conditions encountered on the water, including saltwater exposure, heavy loads, and prolonged use in demanding environments. The design features a **propeller blade configuration** tailored to maximize thrust efficiency while minimizing cavitation and vibration, which helps extend both the life of the screw and the motor itself. This particular screw is part of OMC s **Evinrude E-TEC or E-TEC HP series**, where it plays a critical role in delivering smooth, responsive power transfer from the engine to the water, enhancing acceleration, top-end speed, and overall handling of the vessel.

What sets this screw apart is its **customized geometry**, which includes a **variable-pitch blade design** optimized for specific engine models to balance fuel efficiency, speed, and torque output. The **high-strength alloy construction** ensures resistance to wear and deformation, reducing the risk of blade damage from debris or improper handling. Additionally, the screw is designed with **balanced hydrodynamics**, which minimizes noise and reduces fuel consumption by improving water flow around the blades. Whether used in recreational boats, fishing vessels, or performance watercraft, this screw is engineered to maintain peak performance under varying loads, from leisurely cruising to high-speed maneuvering.

For maintenance and longevity, the **0303247 screw** is designed for easy installation and removal, featuring a **standard drive fit** compatible with Evinrude s proprietary shaft system. It is essential to use the correct torque specifications during installation to prevent stripping or misalignment, which could compromise performance. When stored, it should be kept in a dry, protected environment to prevent corrosion, and regular inspections for signs of wear or damage are recommended. As an **OEM replacement part**, this screw guarantees compatibility with the original equipment specifications, ensuring that your Evinrude outboard operates at its intended efficiency and reliability. Whether you re restoring an older model or upgrading an existing setup, the **303247 screw** is a dependable choice for those seeking optimal propulsion and long-term durability in their marine engine.

### **Pros and Cons of Buying a Used OMC Johnson/Evinrude 303247 Screw (Part #0303247) No-Op (NOS) Condition**

1. **Reliability and Performance** The 303247 is a well-regarded outboard motor from the late 1980s/early 1990s, known for its durability and strong power output (typically 150 175 HP). If properly maintained, it can provide years of dependable service.

2. **Compatibility** This model fits a wide range of boats, including older models that may no longer have OEM replacements. It is a common replacement part for similar Johnson/Evinrude engines from the same era.

3. **Potential for Restoration** If purchased in "No-Op" (No Operation) condition, a skilled mechanic or DIY enthusiast could restore it to working order. Many parts are still available through aftermarket suppliers or salvage yards.

4. **Lower Upfront Cost** Compared to a new outboard, a used NOS unit is significantly cheaper, making it an attractive option for budget-conscious buyers.

5. **Collectible Value** Some older Johnson/Evinrude models hold value among collectors, especially if they are rare or in good condition. If you plan to restore and sell later, this could be a profitable venture.

6. **Ease of Maintenance** Many mechanics are familiar with this model, and parts (such as carburetors, impellers, and seals) are still available, reducing long-term repair costs.

7. **Fuel Efficiency (Compared to Modern Engines)** While not as efficient as newer models, it operates well for recreational use and may be more cost-effective for occasional boating.

---

1. **Age and Wear** Even in NOS condition, the motor may have hidden wear (e.g., cracked casings, worn bearings, or corroded internals). Without a thorough inspection, you risk purchasing a unit that requires extensive repairs.

2. **Limited Availability of Original Parts** While some parts exist, others (especially rare or discontinued components) may be difficult to source. This could lead to higher repair costs if something fails.

3. **Environmental and Emissions Concerns** Older outboards do not meet modern emissions standards, which could be an issue if you plan to use it in regulated areas or for commercial purposes.

4. **Fuel and Oil Requirements** This engine likely runs on older fuel formulations (e.g., leaded or lower-grade gasoline), which may be harder to find or less efficient than modern fuels.

5. **Resale Value** Unlike newer engines, this model will not retain much resale value. If you decide to sell it later, you may struggle to recoup a significant portion of the purchase price.

6. **Potential for Hidden Damage** Without a professional inspection, you could unknowingly buy a motor with internal damage (e.g., cracked blocks, seized pistons, or failed seals), leading to costly repairs.

7. **Warranty Issues** Since this is a used NOS part, there is no manufacturer warranty. Any issues discovered after purchase will be your responsibility to fix.

8. **Compatibility with Modern Boats** Some newer boats may have electronic ignition or fuel injection systems that are not compatible with this older engine, requiring additional modifications.

Buying a used OMC Johnson/Evinrude 303247 screw (Part #0303247) in NOS condition can be a cost-effective solution if you are prepared for potential repairs, have mechanical experience, or plan to restore it as a project. It is ideal for:

- Boaters with older boats that require a reliable but affordable replacement.

- Enthusiasts who enjoy restoring classic engines.

- Those who prioritize performance and durability over modern efficiency.

- Need a motor with minimal hassle or warranty coverage.

- Plan to use it frequently without maintenance.

- Are looking for a long-term, low-maintenance solution.

---

1. **Inspect Thoroughly** Have a marine mechanic perform a pre-purchase inspection to check for internal damage, corrosion, or wear. Look for signs of proper storage (e.g., no rust, intact seals).

2. **Test Run (If Possible)** If the seller allows, have the motor run briefly to ensure it starts and operates smoothly.

3. **Budget for Repairs** Allocate extra funds for potential restoration work, especially if you lack mechanical experience.

4. **Consider Alternatives** If your primary goal is reliability, a newer used outboard (even if not NOS) may offer better long-term value with fewer surprises.

5. **Check for Parts Availability** Verify that critical components (e.g., carburetor, impeller, gaskets) are still in production or easily obtainable.

**Final Verdict:** This motor is a solid buy for the right buyer someone who understands the risks and is willing to invest time and effort into its upkeep. For casual or frequent boaters seeking convenience, a newer or well-maintained used engine may be a safer investment.
