The **OMC 172790 Evinrude Top Mount Kit** is designed to replace or upgrade an existing Evinrude outboard motor with a top-mount configuration, typically used for inboard/outboard (I/O) or sterndrive applications. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

---

### **Pros of the OMC 172790 Evinrude Top Mount Kit**

1. **Compatibility with Existing Systems**

The kit is engineered to integrate seamlessly with Evinrude s top-mount outboards, which are commonly used in I/O or sterndrive setups. This means it can replace an older or damaged motor without requiring major modifications to the boat s transom or drive system.

2. **Performance and Efficiency**

Evinrude top-mount motors are known for their reliability and performance, offering strong horsepower and torque for tasks like towing, planing, or cruising. The 172790 model (assuming it falls within a mid-range power class, e.g., 150 250 HP) provides a balance of speed and fuel efficiency, depending on the specific engine variant.

3. **Ease of Installation**

Top-mount kits are generally easier to install than full sterndrive conversions because they attach directly to the boat s transom via a bracket or mounting plate. This reduces labor time and complexity compared to inboard/outboard setups that require extensive plumbing and wiring.

4. **Fuel Injection and Modern Technology**

Newer Evinrude top-mount motors (especially those from the last decade) feature fuel-injected engines, which improve fuel efficiency, reduce emissions, and provide smoother operation compared to older carbureted models.

5. **Versatility**

The kit can be used for a variety of boat types, including fishing boats, cruisers, or utility vessels. It s also compatible with Evinrude s electronic control systems, such as the **Evinrude E-TEC** or **Evinrude E-TEC2**, which offer features like shift-on-the-fly, throttle control, and diagnostic tools.

6. **Resale Value and Market Demand**

Evinrude is a well-regarded brand, and top-mount motors retain decent resale value. If you plan to sell the boat later, having a reliable Evinrude motor can be a selling point.

7. **Warranty Coverage**

OMC (a division of Brunswick) typically offers warranties on new motors, which can provide peace of mind for the initial ownership period. Warranty terms vary, so it s important to review the specific coverage included with the kit.

8. **Reduced Maintenance Complexity**

Top-mount motors are generally simpler to maintain than inboard engines because they are more accessible. Tasks like oil changes, spark plug replacements, and basic tune-ups can be done more easily without disassembling the boat s interior.

### **Cons of the OMC 172790 Evinrude Top Mount Kit**

1. **Limited Power Output for Large Boats**

Depending on the specific horsepower of the 172790 kit, it may not be sufficient for very large or high-performance boats. For example, a 150 200 HP motor might struggle to adequately power a 30-foot cruiser or a boat designed for heavy towing. You d need to verify the exact HP rating of the kit to ensure it matches your boat s requirements.

2. **Weight Considerations**

Top-mount motors can be heavy, especially when paired with a drive unit. This may require reinforcement of the transom or additional support structures to prevent stress on the boat s hull. Overloading the transom can lead to long-term damage.

3. **Noise and Vibration**

While Evinrude motors are generally well-built, top-mount setups can still produce noticeable noise and vibration, particularly at higher speeds. This may be less of an issue for fishing boats or work vessels but could be a drawback for quiet cruising.

4. **Fuel and Maintenance Costs**

Higher-performance motors consume more fuel, especially if used for extended periods at high speeds. Additionally, top-mount engines require regular maintenance, such as oil changes, filter replacements, and propeller care, which can add to the long-term cost of ownership.

5. **Compatibility with Older Boats**

If your boat is older or not originally designed for a top-mount setup, you may need to invest in additional modifications, such as transom reinforcement or electrical upgrades, to ensure proper installation and operation.

6. **Limited Customization**

Unlike inboard engines, top-mount motors offer fewer customization options in terms of gear ratios, shaft lengths, or drive configurations. You re largely limited to the specifications provided by the kit.

7. **Potential for Overheating**

Top-mount motors rely on external cooling, which can be affected by poor water flow or clogged cooling systems. Inboard/outboard setups with dedicated water pumps are generally more robust in this regard.

8. **Resale Depreciation**

While Evinrude motors hold value reasonably well, top-mount setups may depreciate faster than newer sterndrive or inboard/outboard hybrids, depending on market trends and boat type.

### **Conclusion**

The **OMC 172790 Evinrude Top Mount Kit** is a solid choice for boat owners looking to upgrade or replace an existing Evinrude motor in a top-mount configuration. It offers reliability, ease of installation, and compatibility with a wide range of boats, making it ideal for fishing, utility, or mid-sized cruising applications. The kit s modern features, such as fuel injection and electronic controls, further enhance its appeal for those seeking a balance of performance and convenience.

However, the kit may not be suitable for very large or high-performance boats, as its power output could be limiting. Additionally, the weight and potential for noise or vibration should be considered, especially if you prioritize a smooth, quiet ride. Maintenance and fuel costs are also factors to weigh, particularly if you plan to use the boat frequently or for extended periods.

### **Recommendation**

- You own a boat that is compatible with a top-mount Evinrude motor (e.g., a fishing boat, cruiser, or utility vessel).

- You need a reliable, mid-range power solution (verify the exact HP rating to ensure it matches your boat s requirements).

- You prefer the simplicity of installation and maintenance over the complexity of an inboard/outboard hybrid.

- You value Evinrude s brand reputation and warranty coverage.

- Your boat s transom is structurally sound to support the motor s weight.

- Your boat requires significantly more power than the kit provides (e.g., heavy towing or large displacement hulls).

- You plan to use the boat primarily for high-speed cruising or racing, where a more powerful sterndrive might be preferable.

- Your boat s transom lacks the reinforcement needed to safely support the motor.

- You re on a tight budget and cannot afford the ongoing fuel or maintenance costs associated with a higher-performance motor.

- If you re unsure about the power requirements, consult a marine mechanic or Evinrude dealer to confirm the 172790 kit s compatibility with your boat.

- For boats requiring more power, consider a higher-horsepower Evinrude sterndrive or inboard/outboard setup.

- If you re looking for a quieter ride, explore models with vibration-dampening features or consider an inboard engine if your boat is designed for it.

Ultimately, the 172790 kit is a practical and efficient upgrade for many boat owners, provided their needs align with the motor s capabilities. Always verify the specific model s specifications and consult with a professional to ensure the best fit for your vessel.
