Overview / What Is the New Saturn – Yamaha (13.75 x 13″) Solas LH Propeller?

The Solas 3432-138-13 is a stainless steel, left-hand rotation propeller manufactured to deliver peak efficiency and torque transmission for Yamaha outboard motors. It belongs to the renowned Solas New Saturn series, known for its sturdy build and smooth acceleration characteristics. This propeller fits various Yamaha engines that utilize a 15-spline shaft and is especially suitable for users operating in challenging saltwater and freshwater environments.

This propeller’s key strength lies in its progressive pitch blade design, which allows for enhanced thrust and a better hole shot at lower RPMs. Built for 4-stroke Yamaha engines ranging from 50HP to 130HP, it provides a perfect balance between acceleration and top speed. If you’re looking for a consistent performer with minimal cavitation, this saturn yamaha propeller marine product is designed for you.

Benefits of the 13.75 x 13” Solas LH Propeller

• Built for Yamaha: Precision-crafted for Yamaha outboard engines for seamless compatibility.
• Durable Stainless Steel: Corrosion-resistant and impact-tolerant — ideal for saltwater use.
• Improved Acceleration: Designed with blade geometry that maximizes thrust from standstill.
• Efficient Mid-Range RPMs: Great for cruising and fuel savings without over-revving the engine.
• Left-Hand Rotation: Ideal for twin-engine setups needing counter-rotating props.

How to Install a Saturn Yamaha Propeller for Marine Use

Installation of the Solas 3432-138-13 LH Propeller is a relatively straightforward process but requires careful attention to ensure proper alignment and torque. First, remove the existing propeller and inspect the shaft for wear or corrosion. Clean the spline and apply a marine-grade anti-seize lubricant. Install the thrust washer, align the propeller onto the splines, and use the original hardware to secure it with a locking tab or cotter pin.

Using a torque wrench, tighten the propeller nut according to Yamaha’s specifications. Always test the propeller by rotating it manually to ensure there is no contact or obstruction before water trials. This ensures you get the best performance from your saturn yamaha propeller marine upgrade.

Best Saturn Yamaha Propeller Marine Options and Alternatives

While the Solas 3432-138-13 offers exceptional balance and durability, you may want to compare it to other pitch sizes in the New Saturn series depending on your boating preferences. For heavier loads or slower cruising, lower-pitch options like 11” might provide better hole shot, while higher-pitch options around 15” can enhance top speed on lighter boats.

Other Solas propeller lines such as the Amita 3 or HR Titan are worth considering if you need aluminum or high-rake designs. However, the New Saturn remains one of the best stainless steel options for consistent marine performance with Yamaha outboards.

Maintenance Tips

Maintaining your New Saturn Yamaha LH Propeller not only extends its lifespan but also ensures optimal engine performance. Here’s how to keep it in top shape:

• Inspect Regularly: Check for dings, cracks, or fishing line wraps after each trip.
• Rinse with Freshwater: Always rinse the propeller with freshwater after saltwater use to avoid corrosion buildup.
• Lubricate Shaft: Apply marine grease to the shaft during installation and reapply every few months.
• Seasonal Removal: Take off the propeller during off-season to prevent corrosion or shaft seizing.
• Balance and Alignment: If you experience vibrations, have the propeller inspected and balanced professionally.

These propeller maintenance tips ensure that your boating experience remains smooth, safe, and fuel-efficient.

Expert Advice and Pro Recommendations

Marine experts recommend the Solas 3432-138-13 for those looking to strike a balance between power and precision in boating. This propeller is often used in twin-outboard configurations requiring a left-hand unit to pair with a right-hand counterpart.

Troubleshooting Common Yamaha Propeller Issues

If you’re facing performance issues with your Yamaha outboard, your propeller could be the culprit. Common problems include cavitation, slow planing, and engine over-revving. For each of these symptoms, the pitch or condition of your propeller may be mismatched or compromised.

Check for physical damage on the blades or signs of hub slippage. If you’re frequently dealing with cavitation, upgrading to the New Saturn stainless steel blade can significantly reduce this by offering sharper, more hydrodynamic blade edges. When troubleshooting saturn yamaha propeller marine performance issues, always start by inspecting the prop’s alignment, shaft tightness, and RPM match to your boat’s specifications.

Detailed FAQ Section

1. What boats are best suited for the 13.75 x 13” Solas LH Propeller?

This propeller is most compatible with Yamaha outboards from 50HP to 130HP that require a left-hand rotating prop. Boats that benefit include mid-size fishing boats, family cruisers, pontoons, and twin-engine setups where counter-rotation is essential. The 13” pitch is ideal for mixed use — providing good hole shot and mid-range performance.

It’s also a great match for boats that often operate at variable speeds, such as water sport boats or those frequently used in rivers and coastal waters. Due to its stainless steel build, it’s especially suitable for saltwater applications, making it a durable choice for both professionals and weekend boaters.

2. What is the difference between LH and RH propellers?

LH (left-hand) and RH (right-hand) propellers rotate in opposite directions. RH is the standard direction, but LH is required for twin-outboard boats to balance torque and improve handling. For single-engine applications, it’s crucial to match your propeller direction to your engine’s specification. Installing the wrong rotation can cause thrust issues and reduce handling performance.

The New Saturn LH propeller is specifically designed for engines that spin counter-clockwise when viewed from the rear. It’s essential to check your engine manual or consult your boat technician before purchase to ensure proper rotation direction compatibility.

3. How do I know if I need to replace my propeller?

Signs that it’s time to replace your propeller include increased engine vibration, difficulty planing, slow acceleration, or visible blade damage. If your propeller has small dings, it may still be usable but should be balanced and inspected. Major cracks, bent blades, or worn hubs demand immediate replacement.

Even if the propeller looks fine, internal hub degradation could be affecting performance. Replacing your worn prop with a saturn yamaha propeller marine like the Solas 3432-138-13 will restore your boat’s performance and protect your engine from strain or inefficiency.

4. How much speed can I expect from the Solas 3432-138-13?

The exact speed gain or loss depends on your boat size, load, and engine HP. However, the 13” pitch generally offers a well-balanced performance that maximizes mid-speed cruising efficiency and provides moderate top speed gains without sacrificing hole shot. Many users report a 2–3 MPH improvement over older aluminum propellers and smoother transitions when throttling up or down.

This model is best suited for applications where consistency and torque under varying load conditions are priorities. For more top-end speed, you could consider switching to a 15” pitch, depending on engine compatibility and current RPM range.

5. Can I install this propeller myself, or do I need a professional?

Yes, most users with basic mechanical skills can install the Solas 3432-138-13 LH propeller themselves using a prop wrench, grease, and a cotter pin. Make sure to follow Yamaha’s guidelines for installation and torque settings. A prop installation kit or hub kit can also help reduce vibration and simplify the process.

If you’re unsure about the fitment or feel uncomfortable with marine installations, a certified boat technician can complete the installation in less than 30 minutes. Always verify the shaft size and spline count before installing a new propeller to avoid misalignment or vibration issues.

Conclusion

The New Saturn – Yamaha (13.75 x 13″) Solas LH Propeller, 3432-138-13 is a powerful addition to any Yamaha outboard propulsion system.
