How to Install the Lexor RH Propeller
Installing the Lexor RH Propeller is a straightforward process, but requires attention to detail for safety and performance. Start by ensuring the engine is off and the ignition key is removed. Then, use a wrench to loosen and remove the prop nut and any washers or spacers. Slide the old propeller off and inspect the shaft for debris or corrosion.
After applying marine grease to the shaft, align the new Lexor RH Propeller with the splines and push it into place. Reinstall the spacer, washers, and prop nut. Torque the nut according to your engine’s specifications and use a cotter pin or locking mechanism to secure it. Always test the installation before heading out to the water.
Benefits of Stainless Steel Marine Propellers
Stainless steel marine propellers like the Lexor 15 x 21 RH are known for their resilience and performance. Unlike aluminum, stainless steel doesn’t flex under load, allowing for more consistent blade geometry and better propulsion. This makes them ideal for high-speed applications and rough marine conditions.
Stainless steel also offers better fuel economy, improved handling, and greater acceleration because of the material’s strength. While they may cost more upfront, stainless steel props like the Lexor RH Propeller are more cost-effective over time due to their durability and low maintenance needs.
Maintenance Tips
Proper maintenance of your Lexor RH Propeller will extend its lifespan and ensure consistent performance. After each boating session, inspect the propeller for nicks, dings, or fishing line entanglement. Clean it thoroughly using freshwater, especially after saltwater use, to remove corrosive elements.
Apply marine-grade lubricant to the shaft regularly, and always store the propeller in a dry, protected place when not in use. Perform a thorough inspection during routine boat maintenance to ensure the blades remain in top shape. Promptly replace or repair any damaged components to prevent costly repairs down the line.

Performance and Efficiency in Marine Conditions
Real-world use of the Lexor RH Propeller for marine conditions reveals outstanding results. Users report faster planing times, improved fuel efficiency, and better responsiveness in turns. The 15 x 21” dimension is optimal for balancing RPM and top-end speed, especially on mid-sized outboards between 90-150 HP.
Marine enthusiasts also highlight the Lexor’s ability to perform well under load, making it ideal for towing sports or transporting heavy gear. With its refined blade design and rigid material, it’s a perfect fit for serious boaters.
Troubleshooting Common Propeller Issues
Even the best propellers may encounter issues if not properly maintained. Common problems include cavitation, ventilation, and vibration. Cavitation occurs when air bubbles form around the blades, reducing thrust. This is often due to damage or incorrect pitch.
Ventilation involves the engine over-revving because air is getting under the blades, usually from improper installation or damaged parts. If you experience unusual vibration, inspect the propeller for bends or dings and replace as needed. The Lexor RH Propeller’s robust design reduces the chances of these issues, but awareness and proactive care go a long way.
Detailed FAQ Section
What size boat is ideal for the Lexor 15 x 21 RH Propeller?
The Lexor 15 x 21 RH Propeller is suitable for mid-sized to large recreational boats and fishing vessels powered by Evinrude, Johnson, or OMC outboards. Generally, boats with engine sizes ranging from 90 to 150 HP benefit most from this propeller. It provides a perfect balance between thrust, speed, and fuel efficiency.
Can I install this propeller myself or should I hire a professional?
Yes, you can install the Lexor RH Propeller on your own if you’re comfortable with basic tools and marine hardware. The process includes removing the old prop, applying grease, aligning the new one on the shaft, and securing it with a nut. However, if you’re unsure or dealing with other mechanical issues, it’s best to consult a marine technician to ensure everything is properly torqued and safe.
How do I maintain my Lexor stainless steel propeller?
Rinse the propeller with freshwater after every use, especially in saltwater environments. Check regularly for damage, wrap-around debris, and shaft lubrication. Applying marine grease and storing it in a safe place will prevent rust and keep performance optimal. An annual inspection is also recommended before the boating season begins.
What’s the difference between RH and LH propellers?
RH (right-hand) propellers rotate clockwise, while LH (left-hand) propellers rotate counter-clockwise. Most outboard engines are designed for RH propellers. The Lexor 4571-150-21 model is RH, making it compatible with a wide range of standard Evinrude, Johnson, and OMC engines. If you’re unsure which you need, check your engine’s manual or consult a marine expert.
Why choose a Lexor stainless steel prop over an aluminum one?
Stainless steel propellers like the Lexor RH offer superior strength, durability, and efficiency. They don’t flex under load, maintain blade shape, and deliver consistent performance even in rough waters. While aluminum props are cheaper, stainless steel versions last longer and reduce long-term costs due to fewer replacements and repairs.
