Detailed FAQ Section
What boats are compatible with the Lexor Plus 15.75 x 21″ propeller?
The Lexor Plus 15.75 x 21″ propeller is compatible with a wide range of mid-to-high horsepower Suzuki outboard engines, particularly in the 150HP to 250HP range. It’s an excellent match for boats such as bay boats, center consoles, deck boats, and even some high-performance hulls. The large diameter and higher pitch are well-suited for heavier boats or those that prioritize speed and load-handling performance. Always refer to your outboard manufacturer’s propeller chart for compatibility before purchasing.
How does the Lexor Plus improve boat performance?
This propeller is designed with high-rake, cupped blades that offer better grip in the water. As a result, users experience quicker hole shots, better acceleration, and increased fuel efficiency. The stainless steel design ensures the prop retains its shape and performance under load and at higher speeds. The Lexor Plus also helps reduce cavitation and ventilation — two major concerns for many boaters. This means a smoother ride and more responsive handling in rough waters.
Can I install the Lexor Plus propeller myself?
Yes, installation is relatively simple for most DIYers with basic mechanical skills. All you need is a wrench, marine grease, and a Rubex hub kit compatible with your outboard. Detailed installation instructions come with most hub kits, and numerous tutorials are available online. Always ensure you tighten the propeller nut to the recommended torque settings and secure it with a cotter pin or locking device. If you’re unsure, professional installation is advised to avoid damaging the propeller or drive shaft.
How do I know if I need a 21” pitch propeller?
Pitch selection depends on your boat’s weight, engine RPM, and desired performance. A 21” pitch propeller like the Lexor Plus is typically used when seeking higher top-end speed without over-revving the engine. If your current RPM is at or near the upper end of the manufacturer’s range, switching to a 21” pitch could lower RPM slightly while increasing speed. For best results, conduct RPM tests and consult with marine propeller experts to ensure optimal fitment and performance.
How does the Lexor Plus compare to aluminum propellers?
Stainless steel propellers like the Lexor Plus outperform aluminum in strength, longevity, and performance. Aluminum props are more affordable but tend to flex under high loads, reducing efficiency. In contrast, stainless props maintain blade integrity, deliver stronger thrust, and provide faster acceleration and top speeds. While they are more expensive, the durability and improved performance of stainless steel like the Lexor Plus make them a better long-term investment for serious boaters.
Conclusion
The Lexor Plus – Suzuki (15.75 x 21″) Solas RH Propeller, 4571-158-21 is a standout choice for marine enthusiasts looking to elevate their performance on the water. With durable stainless steel construction, enhanced cupping, and optimized blade design, it provides superior thrust, handling, and speed.
