Overview / What Is Lexor 4 – Suzuki Solas Propeller?

The Lexor 4 is a four-blade, right-hand rotation propeller made of durable stainless steel, precision-engineered to match the performance demands of Suzuki outboard motors. Measuring 15.25 inches in diameter with a 20″ pitch, it offers excellent lift, stability, and speed balance for various boat types and water conditions. Solas, a leading marine propeller manufacturer, designed this model under the Lexor series to meet the needs of high-torque and high-thrust propulsion.

Key specs include corrosion-resistant stainless steel, expertly cupped blades for better acceleration, and an advanced blade geometry that maximizes surface area for superior thrust. With this propeller, boaters can expect higher midrange efficiency, smoother rides, and improved fuel economy—making it a go-to upgrade for performance-focused marine enthusiasts.

Key Features of the 4573-153-20 Solas Propeller

  • Constructed from high-grade stainless steel for corrosion resistance
  • Four-blade configuration for enhanced thrust and grip in the water
  • Right-hand rotation ideal for standard Suzuki outboards
  • Diameter: 15.25″, Pitch: 20″
  • Engineered for superior midrange fuel economy and power

This model is specifically tuned to reduce cavitation, minimize slippage, and maximize the outboard’s horsepower output at optimal RPM ranges.

Why Choose a Stainless Steel Propeller Over Aluminum?

Stainless steel propellers like the Lexor 4 offer a significant performance advantage over their aluminum counterparts. Stainless steel is five times stronger than aluminum, meaning the blades maintain their shape under heavy loads and high speeds. This results in better acceleration, handling, and fuel efficiency over time.

While stainless steel props typically cost more upfront, they often last 2–3 times longer than aluminum versions, making them a smarter investment in the long run—especially for boaters who frequently navigate coastal waters or saltwater environments.

How to Install the Lexor 4 Solas RH Propeller

Installing the Lexor 4 – Suzuki Solas Propeller requires some mechanical know-how and the right tools. Here’s a simplified installation guide:

  1. Ensure your engine is off and the battery disconnected.
  2. Remove the cotter pin and propeller nut using a socket wrench.
  3. Slide off the old propeller and inspect the shaft for fishing line or debris.
  4. Apply marine grease to the shaft before mounting the new propeller.
  5. Install the Lexor 4 propeller and secure it with the thrust washer, prop nut, and a new cotter pin.

Always refer to the manufacturer’s installation guide and consult your marine mechanic if unsure.

Maintenance Tips

To extend the life of your Lexor 4 – Suzuki Solas RH Propeller, routine maintenance is crucial. Stainless steel offers long-term durability, but like any marine component, regular care will keep it performing at its peak.

  • Inspect the propeller for dings, cracks, or bent blades after every boating trip.
  • Rinse with fresh water after use in saltwater to prevent corrosion buildup.
  • Check and grease the prop shaft every 20–30 hours of operation.
  • Replace cotter pins and damaged hardware during propeller servicing.

Neglecting prop maintenance can lead to performance drops, vibration issues, and fuel inefficiency. Keep a prop wrench and marine grease in your onboard tool kit for emergencies.

Detailed FAQ Section

What makes the Lexor 4 better than other 4-blade propellers?

The Lexor 4 stands out due to its high-quality stainless steel construction, advanced blade design, and tailored compatibility with Suzuki engines. Its cupped blades increase bite, resulting in reduced ventilation and slippage, especially under load or during sharp turns. Compared to standard 4-blade props, Lexor 4 offers better midrange fuel efficiency and higher top-end stability. It’s a premium option for serious boaters looking for durability and performance in one package.

Can I replace my 3-blade prop with this Lexor 4 model?

Yes, switching from a 3-blade to a 4-blade propeller like the Lexor 4 is common and can offer notable advantages. Four-blade props provide quicker planing, improved low-speed maneuverability, and enhanced control in rough water. However, you may lose a small amount of top-end speed. It’s crucial to consult your engine’s RPM range and possibly reduce the pitch by 1” if making the switch to ensure optimal performance.

How do I know if this propeller fits my Suzuki outboard?

The Lexor 4 – Solas RH Propeller, 4573-153-20, is designed for Suzuki outboards, particularly 150–300 HP models. To ensure compatibility, check your current prop’s hub design and spline count, or refer to your outboard’s user manual. Most Suzuki props have a standard 15-tooth spline and match this propeller’s hub dimensions. If you’re unsure, contact your dealer or use an online prop fitment tool before purchase.

How long does a stainless steel propeller typically last?

Stainless steel propellers like the Lexor 4 can last anywhere from 5 to 10 years with proper care. Longevity depends on usage frequency, water conditions, and maintenance habits. Compared to aluminum props, stainless options resist flexing, corrosion, and physical impact better. Regular inspections, greasing the shaft, and rinsing after saltwater use will help maximize the propeller’s lifespan. Always replace or repair blades with visible cracks or significant dings to avoid engine strain.

Is the Lexor 4 worth the investment for recreational boaters?

Absolutely. While the Lexor 4 may have a higher upfront cost, its long-term benefits in performance, fuel savings, and reduced maintenance make it a solid investment—even for weekend boaters. Its stainless steel build resists damage better than aluminum, and its design enhances ride quality in diverse marine conditions. Whether you fish, cruise, or ski, this propeller delivers reliability and smooth operation over many seasons.

Conclusion

The Lexor 4 – Suzuki (15.25 x 20″) Solas RH Propeller, 4573-153-20 is a top-tier marine propeller designed to elevate your boat’s handling, speed, and fuel efficiency.
