Review YAMAHA 115hp Txr Stroke Outboard Iac Valve Control Unit fits 2005

The **Yamaha 68V 13105-00-00 115 Horsepower TXR 2005 Outboard** is a high-performance marine engine designed for both recreational boating and serious anglers seeking reliability, efficiency, and cutting-edge technology. This model belongs to Yamaha s legendary **TXR series**, renowned for its advanced fuel-injected, four-stroke architecture, which delivers a perfect balance of power, fuel economy, and low emissions. With a robust **115 horsepower** output, this outboard is engineered to propel mid-sized boats ranging from fishing vessels to cruisers with effortless speed and precision, while maintaining exceptional durability for years of demanding use. One of the standout features of this engine is its **Intelligent Automatic Control (IAC) Valve Control Unit**, a sophisticated electronic system that optimizes throttle response, fuel delivery, and overall engine performance. This unit dynamically adjusts the intake air flow and fuel mixture in real-time, ensuring smoother acceleration, reduced wear on internal components, and improved fuel efficiency even under varying load conditions. The IAC system also enhances the engine s cold-start capabilities, allowing for quicker and more reliable ignition in cooler temperatures, which is particularly beneficial for early-season fishing trips or extended periods of inactivity. Built with Yamaha s signature attention to detail, this outboard incorporates a **durable aluminum housing**, a **high-performance cylinder head**, and a **robust exhaust system** that not only maximizes power output but also minimizes noise and vibration for a quieter, more comfortable ride. The **TXR s fuel-injected design** eliminates the need for carburetion, reducing the risk of clogging and simplifying maintenance, while its **direct ignition system** ensures precise spark timing for optimal combustion. Whether you re trolling for bass, cruising along the coast, or navigating through choppy waters, this 2005 Yamaha 68V 115HP outboard delivers a seamless blend of power, efficiency, and advanced engineering making it a dependable workhorse for both casual and serious boaters alike.

### **Pros and Cons of Buying a 2005 Yamaha 68V 13105-00-00 (115 HP) TXR Outboard with IAC Valve Control Unit**

#### **Pros**

1. **Reliable Brand Reputation** Yamaha is a well-known manufacturer with a strong track record for durability and performance in outboard motors. The 68V series is particularly respected for its balance of power and efficiency.

2. **Good Power-to-Weight Ratio** At 115 horsepower, this engine is suitable for mid-sized boats (18 24 feet) and offers strong acceleration and cruising performance. It strikes a balance between speed and fuel economy compared to larger engines.

3. **Fuel Efficiency** Relative to its power class, the 68V series is known for reasonable fuel consumption, making it cost-effective for recreational boating compared to higher-horsepower outboards.

4. **Lower Maintenance Costs (Compared to Larger Engines)** Smaller outboards generally require less frequent maintenance than larger, high-performance engines. The 68V is designed for durability with fewer complex components.

5. **IAC (Idle Air Control) Valve** The inclusion of an IAC valve suggests the engine has modernized idle control, which can improve smoothness and reduce emissions compared to older carbureted models. This feature also makes it easier to fine-tune idle settings.

6. **Resale Value** Yamaha outboards hold their value well, especially in the mid-range power category. A well-maintained 2005 model can still fetch a decent price in the used market.

7. **Versatility** The 68V is versatile for various applications, including fishing boats, cruisers, and small wakeboard boats, depending on the boat s setup.

8. **Easier to Handle Than Larger Engines** At 115 HP, it s manageable for single-handed operation on smaller boats, whereas larger outboards (e.g., 200 HP) require more effort to start, maneuver, and maintain.

9. **Proven Reliability Over Time** The 2005 model year is not extremely old, and Yamaha s 68V engines from this era are known for lasting well with proper care. Many still operate reliably after 15 years.

10. **Accessibility of Parts and Mechanics** Yamaha parts are widely available, and mechanics familiar with the brand are common, reducing downtime if repairs are needed.

#### **Cons**

1. **Age and Potential Wear** Being from 2005, the engine has been running for nearly two decades. Wear on critical components like the lower unit seals, impeller, and timing chain could be an issue if maintenance records are unavailable. Rust or corrosion in saltwater applications is also a concern.

2. **Electronic IAC Valve Reliability** While the IAC valve improves idle control, electronic components can fail over time. If the valve malfunctions, it may cause rough idling, stalling, or require professional diagnostics and repair.

3. **Fuel System Depreciation** Older outboards may develop issues with fuel injectors, fuel pumps, or carburetor components (if not electronically controlled). A fuel system flush or rebuild may be needed.

4. **Lower Emissions Compliance** The 2005 model predates stricter emissions regulations (e.g., EPA Tier 3), meaning it may not meet modern environmental standards if used in areas with updated boating laws. However, this is unlikely to be an issue for most recreational use.

5. **Potential for Rust and Corrosion** If the engine was stored improperly or used in saltwater without proper flushing, rust can damage internal components like the lower unit, water pump, and cylinder walls.

6. **Limited Warranty Coverage** The original warranty has likely expired, so any repairs would be out-of-pocket. Extended warranties (if available) may not cover pre-existing issues.

7. **Fuel and Oil Requirements** Older Yamaha engines may require specific fuel treatments (e.g., ethanol-compatible fuel) and high-quality oil to prevent sludge buildup. Neglecting this can lead to engine damage.

8. **Performance Compared to Newer Models** Newer Yamaha outboards (even in the same power class) may offer better fuel efficiency, lower emissions, and advanced features like digital dashboards or remote start. The 2005 model lacks these upgrades.

9. **Lower Resale Value Than Newer Models** While it holds value better than some brands, a 2005 Yamaha will still depreciate more than a 2015 or newer model with similar power.

10. **Potential for Hidden Problems** Without a thorough inspection or service history, issues like a failing alternator, water pump, or timing chain stretch could go unnoticed until they cause failure.

### **Conclusion**

The **2005 Yamaha 68V 115 HP TXR outboard with IAC valve control** is a solid choice for budget-conscious buyers looking for a reliable, mid-sized engine. Its strengths lie in **durability, fuel efficiency, and ease of maintenance**, making it ideal for recreational boating on smaller vessels. However, its **age introduces risks of wear, potential electronic failures, and hidden mechanical issues**, which could lead to unexpected repair costs.

If you are purchasing this engine **new or with a full service history**, it remains a practical and cost-effective option. If buying used without records, **a pre-purchase inspection by a Yamaha-certified mechanic is essential** to check for rust, internal wear, and electronic component health.

---

### **Recommendation**

- You are on a tight budget and can afford potential repairs.

- The engine has a **complete service history** and has been well-maintained.

- You plan to use it in **freshwater or lightly saltwater environments** with proper flushing.

- You are willing to **invest in a pre-purchase inspection** to verify its condition.

- You do not require the latest features (e.g., digital dashboards, remote start).

- You cannot afford unexpected repairs or replacements (e.g., lower unit, impeller, or fuel system).

- The engine has **no service records** or shows signs of neglect (rust, oil leaks, rough idling).

- You plan to use it in **heavily saltwater environments** without proper maintenance.

- You prioritize **modern features** and fuel efficiency over cost savings.

- If budget allows, consider a **2010 2015 Yamaha 60V or 80V model** for better reliability and emissions compliance.

- For a more budget-friendly option, a **used 2008 2012 Mercury or Suzuki in the same power class** may offer comparable performance with slightly newer technology.

- If you need a larger engine, a **2010 Yamaha 150 HP** could provide better long-term value with modern upgrades.

**Final Verdict:** The 2005 Yamaha 68V is a **good value for the price** if purchased carefully, but buyers should prioritize **inspection and maintenance** to avoid costly surprises. For those seeking a balance of affordability and reliability, it remains a viable choice just with the understanding that it is not a "set-and-forget" engine.
