Review RAREELECTRICAL 15.5x13 Propeller Bravo Mag Mpi 15 Spline fits MERCRUISER 350 300 1988–1998

The **Mercruiser Bravo 350 MPI 15 Spline Propeller (Part Number: 1511-155-13I2, 15.5" x 13")** is a meticulously engineered, high-performance propeller designed specifically for the **1988 1998 model year Mercruiser Bravo 350 MPI (Multi-Port Injection) inboard engines** featuring a **15-spline shaft**. This propeller is a premium choice for boat owners seeking optimal efficiency, reliability, and smooth operation in both cruising and performance applications. Crafted from **high-grade, corrosion-resistant stainless steel**, it is built to withstand the harshest marine environments, ensuring long-lasting durability even in saltwater conditions. The **15.5-inch diameter** and **13-inch pitch** combination strikes an ideal balance between acceleration, top-end speed, and fuel economy, making it well-suited for a variety of boating needs, from leisurely cruising to spirited weekend outings. The **three-blade design** enhances hydrodynamic efficiency, reducing drag while maintaining strong thrust, which translates to better fuel efficiency and reduced engine strain. This propeller is particularly well-matched for **300 horsepower applications**, delivering a seamless power delivery curve that complements the Bravo 350 MPI s torque characteristics. Whether used on a **cuddy cabin cruiser, a performance dayboat, or a fishing vessel**, this propeller ensures a quiet, vibration-free ride while maximizing propulsion and handling. For owners of classic or restored Mercruiser-equipped boats, this part is a direct-fit replacement, ensuring an exact match in performance and compatibility. Properly installed and maintained, it will significantly enhance the overall driving experience, making every voyage smoother, more efficient, and more enjoyable.

### **Pros and Cons of buying a 1511-155-13i2 15.5x13 Propeller for a Mercruiser Bravo 350 MPI (1988 1998, 15 Spline, 300 HP)**

#### **Pros:**

1. **Proven Performance** The 15.5x13 propeller is a well-established size for the Bravo 350 MPI, offering a balanced blend of speed and efficiency. It is designed to work well with the engine s power band, providing smooth acceleration and good top-end speed.

2. **Wide Availability** As a common propeller for this engine and era, replacement parts, tuning adjustments, and aftermarket upgrades are relatively easy to find. This makes maintenance and modifications more straightforward.

3. **Good for Cruising and Light Planing** The 15.5x13 is suitable for a mix of cruising and light planing, making it versatile for both leisurely trips and moderate speed cruising. It won t overwork the engine while still providing decent performance.

4. **Durability** High-quality propellers like this one are built to last, especially if properly maintained. The MPI Bravo 350 is a robust engine, and this prop is designed to handle its power output without excessive wear.

5. **Compatibility with Aftermarket Tuning** If you plan to modify the engine (e.g., with a performance chip or turbocharger), this propeller can often be tuned further by adjusting pitch or blade design to match the increased power.

6. **Lower Risk of Cavitation** The 15.5x13 pitch is moderate enough to reduce the risk of cavitation damage, which can occur with overly aggressive props on lower RPMs.

---

#### **Cons:**

1. **Limited Top-End Speed** While adequate for cruising, this propeller may not be optimal for high-speed racing or aggressive planing. If you prioritize speed, a slightly smaller pitch (e.g., 15x13 or 15x12) might be better, but this could sacrifice low-end torque.

2. **Potential for Roughness at Higher RPMs** Some owners report that the Bravo 350 MPI can feel a bit rough or "humpy" at higher RPMs when using this propeller, especially if the engine is not perfectly tuned. This may require minor adjustments to the prop or engine settings.

3. **Weight Considerations** Larger props like this one can add noticeable weight to the stern, which may slightly affect handling and fuel efficiency in extreme cases. However, this is usually negligible for most cruising applications.

4. **Depreciation and Replacement Costs** Older propellers (especially if not well-maintained) may develop pitting or corrosion over time. Replacing a damaged prop can be costly, though this is true of any propeller.

5. **Not Ideal for Heavy Loads** If you frequently tow trailers, carry heavy loads, or operate in rough water, a slightly larger pitch (e.g., 16x13) might provide better low-end torque and pulling power.

6. **Potential for Mismatch with Modified Engines** If the Bravo 350 MPI has been heavily modified (e.g., forced induction, significant power increases), the stock 15.5x13 may no longer be optimal. In such cases, a custom propeller or a different pitch would be necessary.

### **Conclusion and Recommendation**

The **1511-155-13i2 15.5x13 propeller** is a solid choice for a **1988 1998 Mercruiser Bravo 350 MPI** in a **15 spline, 300 HP configuration**, particularly if you prioritize **cruising efficiency, smooth operation, and versatility**. It strikes a good balance between low-end torque and top-end speed, making it suitable for most recreational boating needs.

**Recommendation:**

- **Buy it if:** You want a reliable, easy-to-find propeller that works well out of the box for general cruising, light planing, and everyday use. It s a good starting point before fine-tuning if needed.

- **Consider alternatives if:** You plan to heavily modify the engine (e.g., turbocharging) or prioritize extreme speed. In those cases, a **smaller pitch (e.g., 15x13 or 15x12)** or a **custom propeller** may be better.

- **Check condition carefully:** Ensure the propeller is free of pitting, cracks, or excessive wear. If the engine has been modified, verify that the prop is still appropriate for the new power output.

- **Test and adjust:** After installation, monitor the engine s RPM range and throttle response. If the boat feels sluggish at higher speeds or rough at certain RPMs, a slight pitch adjustment (e.g., to 15x12.5) may improve performance.

**Final Verdict:** This propeller is a **safe, practical choice** for the Bravo 350 MPI in its stock or lightly modified state. It requires minimal hassle and delivers dependable performance for most owners. If you re unsure, consult a marine mechanic or propeller specialist to confirm compatibility with your specific setup.
