Lexor – Yamaha (15 x 21″) Solas LH Propeller, 3572-150-21

Introduction

If you’re looking to enhance the performance and handling of your Yamaha-powered boat, the Lexor – Yamaha (15 x 21″) Solas LH Propeller, 3572-150-21 is your premium choice. This stainless steel marine-grade propeller is precision-engineered for outboard motors, offering superior strength, hydrodynamic performance, and long-term durability in both freshwater and saltwater environments.

Engineered by Solas and tailored for Yamaha, this left-hand rotating propeller delivers a blend of top-speed potential and acceleration efficiency that few other props can match. For serious boaters, anglers, and marine professionals who demand performance, the Lexor 15 x 21″ is more than just a replacement—it’s a serious upgrade.

Overview / What Is Lexor – Yamaha (15 x 21″) Solas LH Propeller?

The Lexor 3572-150-21 is a high-performance stainless steel propeller designed specifically for Yamaha outboard engines requiring left-hand (LH) rotation. With a diameter of 15 inches and a 21-inch pitch, it’s built to provide enhanced top-end speed and maintain smooth, fuel-efficient cruising in varied conditions.

This propeller falls under the “Lexor | Propulsion > Stainless Steel Propellers” category, meaning it’s built with advanced metallurgy and polished to withstand high-torque loads, corrosion from saltwater, and physical impact. Its fine-tuned geometry ensures a quiet and vibration-free ride even at higher RPMs.

Propeller Size and Performance: Why 15 x 21 Matters

Understanding the size of a propeller is key when choosing one. The 15 x 21” measurement means the propeller has a 15-inch diameter and a 21-inch pitch. The diameter affects how much water the propeller moves, while the pitch determines how far the prop will move the boat forward in one rotation.

This combination is perfect for boats aiming for higher speed without sacrificing too much holeshot performance. If you need better top-end cruising, this is the ideal Yamaha propeller for marine enthusiasts who want both speed and stability.

Key Features of the Solas LH Stainless Steel Propeller

• Left-Hand Rotation: Perfect for twin-engine setups or specific Yamaha configurations that require counter-clockwise rotation.
• Stainless Steel Construction: High-resistance alloy prevents corrosion and resists impact far better than aluminum.
• Blade Geometry: CAD-designed blades ensure smoother acceleration, better mid-range RPM performance, and improved fuel efficiency.
• OEM Compatibility: Designed to perfectly fit Yamaha outboards without modifications or special adapters.

These features ensure that the Lexor – Yamaha (15 x 21″) Solas LH Propeller, 3572-150-21 performs efficiently under high-speed and heavy-load conditions.

How to Install Lexor Yamaha 3572-150-21 Propeller

Installing this Yamaha propeller for marine use is a manageable task, especially with the right tools. Follow these steps:

1. Disconnect the battery and shift the motor into neutral.
2. Remove the cotter pin, nut, and washer from the propeller shaft using a prop wrench.
3. Slide off the old propeller and inspect the shaft for fishing line or damage.
4. Apply marine grease to the shaft to prevent corrosion and ease installation.
5. Install the new Lexor propeller, replace the washer and nut, and secure with a new cotter pin.

Note: Always use proper tools and check Yamaha’s official service manual for torque specifications.

Comparing Lexor Propellers: 15 x 19″ vs. 15 x 21″

When choosing between similar propellers, the difference in pitch can significantly impact your boating experience. The Lexor 15 x 19″ propeller offers better low-end torque and faster holeshot performance, making it ideal for towing or watersports. Meanwhile, the 15 x 21″ Solas LH version leans toward speed and fuel efficiency at cruising RPMs.

If your goal is smooth, fuel-saving operation at mid-to-high speeds, the 15 x 21” Lexor is the better option. However, if you need fast acceleration for heavy loads or waterskiing, you might consider the 15 x 19” model instead. Always align your propeller with your specific boating needs.

Maintenance Tips

To extend the life of your Lexor Yamaha 15 x 21” Solas LH Propeller, follow these essential maintenance practices:

• Clean regularly: Wash off salt, algae, and grime after every trip, especially in saltwater.
• Inspect blades: Look for dents, nicks, or cracks. Even minor imperfections can affect performance and cause vibration.
• Lubricate the shaft: Apply marine grease each time you remove or replace the propeller.
• Tighten fasteners: Ensure that the nut and cotter pin are secure before each trip to prevent the prop from loosening mid-use.
• Check for fishing line: Line wrapped around the shaft can damage seals and lead to costly repairs.

Routine care not only prevents expensive repairs but also ensures consistent performance in all water conditions.

Detailed FAQ Section

What kind of boats work best with the Lexor 15 x 21” Yamaha propeller?

This propeller works best with performance and mid-to-large recreational boats powered by Yamaha outboards in the 150–250 HP range. It’s ideal for center consoles, bay boats, and cruisers where top-end speed and fuel economy are key. The 15 x 21″ configuration allows for efficient operation during extended runs, making it perfect for anglers and offshore navigators.

Always ensure your engine accepts LH rotation and check your current pitch before upgrading to avoid performance mismatch.

How do I know if I need a left-hand (LH) or right-hand (RH) propeller?

Most single-engine setups use a right-hand (clockwise) propeller, while twin-engine setups often use one RH and one LH to balance torque and improve handling. Check your existing propeller or consult your engine manual to verify rotation direction. Installing the wrong rotation can negatively impact your boat’s maneuverability and performance.

If you already use an LH prop or have a counter-rotating outboard engine, the 3572-150-21 model is a perfect match.

What are the main benefits of using stainless steel propellers?

Stainless steel propellers like the Lexor Solas LH 15 x 21” are more durable and resistant to corrosion compared to aluminum options. They maintain their shape better under stress, resist cavitation, and provide more efficient thrust at higher RPMs. This translates into smoother acceleration, better fuel economy, and longer-lasting performance—especially in saltwater environments.

Although they cost more upfront, they offer far superior long-term value and reliability.

How often should I service or inspect my Yamaha propeller?

Inspect your Yamaha propeller every 10–15 hours of operation or after each trip in rough water. Look for signs of impact, corrosion, or marine growth. It’s a good practice to remove the propeller every 2–3 months to clean the shaft and apply marine grease.

Seasonal maintenance includes a full inspection, lubrication, and replacement of any worn parts like cotter pins or thrust washers.

Can I switch to this propeller if I currently use a different pitch?

Yes, but be cautious. Switching from a lower pitch (e.g., 19″) to a higher pitch (e.g., 21″) reduces RPM and increases top speed. However, if your engine can’t maintain optimal RPMs, performance may suffer. Always consult your engine’s RPM range and test different props if necessary to find the best balance of acceleration and speed.

The Lexor 15 x 21” is best suited for boats already operating within higher RPM ranges that want improved cruising efficiency.

Conclusion

The Lexor – Yamaha (15 x 21″) Solas LH Propeller is more than a performance upgrade—it’s a durable, marine-ready investment that improves your Yamaha engine’s power delivery and efficiency. Built for saltwater endurance and top-speed reliability, this propeller delivers excellent results for those serious about marine performance.

Whether you’re upgrading from aluminum or seeking better cruise control for long-distance boating, the 3572-150-21 model delivers on all fronts—strength, speed, and economy.
