### **Pros and Cons of Buying a Mercury PLUSiC 125 HP (R117013) Engine with Mercury Ignition Coil (H6T55171ZC) for a Pleasurecraft**
#### **Pros**
1. **Reliable Brand Reputation** Mercury Marine is a well-established manufacturer with decades of experience in marine engine production. Their engines are known for durability and performance in both freshwater and saltwater environments.
2. **High Performance** The 125 HP PLUSiC (Power Optimized for Ultimate Steering and Control) engine is designed for efficiency and smooth operation. It offers strong acceleration and good fuel economy compared to older models, making it suitable for mid-sized boats (e.g., 18 24 feet).
3. **Fuel Efficiency** The PLUSiC technology optimizes fuel delivery, reducing consumption while maintaining power output. This can lead to cost savings over time, especially for frequent boaters.
4. **Ease of Maintenance** Mercury engines are generally easier to service than some competitors. The PLUSiC series features simplified components, such as an integrated fuel pump and optimized cooling systems, which can reduce long-term maintenance hassles.
5. **Compatibility with Modern Boats** The R117013 model is designed for modern pleasurecraft, offering better steering response and control due to its compact and streamlined design. It works well with outboard engines, inboard/outboard (IO) setups, and some stern drive applications.
6. **Warranty Coverage** Mercury engines typically come with a factory warranty (often 2 5 years, depending on the dealer and model). This provides peace of mind against early failures.
7. **Aftermarket Support** Due to Mercury s popularity, replacement parts (including the ignition coil H6T55171ZC) are widely available. This reduces the risk of long wait times for repairs or upgrades.
8. **Versatility** The 125 HP rating makes it suitable for a variety of boats, from fishing boats and cruisers to speedboats, depending on the hull design and load capacity.
9. **Quiet Operation** Modern Mercury engines are designed to run more quietly than older models, improving the overall boating experience.
10. **Resale Value** Well-maintained Mercury engines hold their value reasonably well, making this a practical long-term investment.

#### **Cons**
1. **Higher Upfront Cost** Compared to some generic or lesser-known brands, Mercury engines are premium-priced. The PLUSiC series, in particular, may cost more than basic outboard engines of similar horsepower.
2. **Fuel and Oil Requirements** Mercury engines often require higher-grade fuel (e.g., premium marine diesel or ethanol-blended gasoline) and specific oil formulations to maintain performance and longevity. Using subpar fuel can lead to engine issues.
3. **Saltwater Corrosion Risk** While Mercury engines are built to handle saltwater, prolonged exposure without proper maintenance (e.g., flushing, corrosion inhibitors) can lead to premature wear on components like the ignition coil, alternator, and cooling system.
4. **Complexity of Repairs** While maintenance is generally straightforward, some repairs (e.g., electrical or fuel system issues) may require specialized tools or a marine mechanic s expertise, increasing labor costs.
5. **Depreciation Over Time** Like all marine engines, Mercury PLUSiC models will depreciate. However, if well-maintained, they retain value better than some competitors.
6. **Ignition Coil Reliability Concerns** The specific ignition coil (H6T55171ZC) is a critical component. While Mercury coils are generally durable, they can fail over time due to moisture, electrical issues, or wear. Replacement costs can add up if the engine is used frequently.
7. **Weight and Space Considerations** The R117013 is a mid-sized engine, which may require additional mounting space or reinforcement on the boat s transom, especially for heavier or larger vessels.
8. **Environmental Regulations** Depending on the region, boaters may need to comply with emissions standards (e.g., EPA or CARB certifications), which could limit older engine models or require upgrades.
9. **Fuel Pump Dependence** The PLUSiC s integrated fuel system can be a double-edged sword. While efficient, a failure in the fuel pump or injectors can lead to sudden power loss, requiring costly repairs.
10. **Limited Lifespan Compared to Diesel** Gasoline engines like this one typically have a shorter lifespan (1,500 3,000 hours) compared to diesel engines (often 3,000 5,000 hours), though proper maintenance can extend their service life.
