Overview / What Is Rubex L3 Plus Propeller
The Rubex L3 Plus is a three-blade, left-hand stainless steel propeller specifically designed for performance, stability, and corrosion resistance. It’s part of the larger Rubex series that supports various engine brands and boat types.
With a diameter of 15.75 inches and a pitch of 21 inches, this propeller offers optimal balance between speed and thrust. Whether you’re cruising or towing, it adapts with precision. The interchangeable hub kit system used in Rubex models helps reduce vibrations and protects your engine gears from shock damage.

- Thick-ribbed hub for strength and reduced cavitation
- Highly polished stainless steel for corrosion resistance
- Quiet performance with rubber hub shock absorption
Why Choose a Stainless Steel LH Propeller?
Left-hand (LH) propellers are essential in twin-engine setups or specific single-engine configurations. They provide counter-rotation and reduce steering torque, making them ideal for better handling in heavier boats or harsh water environments.
Choosing a stainless steel propeller like the Rubex L3 Plus brings added strength and resistance to impact, allowing you to navigate shallow or debris-filled waters with confidence. Unlike aluminum alternatives, stainless steel holds its shape under stress, improving long-term performance and fuel economy.
How to Install Rubex L3 Plus Propeller
Installing the Rubex L3 Plus (15.75 x 21″) Solas LH Propeller, 9572-158-21 is a straightforward process, especially thanks to the interchangeable Rubex hub system. Here’s how:
- Ensure your engine is turned off and remove the existing propeller using a wrench.
- Inspect the propeller shaft for fishing line or debris, clean thoroughly.
- Install the Rubex hub kit into the new propeller (sold separately if needed).
- Slide the new Rubex L3 Plus onto the propeller shaft and secure with thrust washer and nut.
- Tighten using a torque wrench to the engine manufacturer’s specifications.
Note: Always use marine-grade grease on the shaft before installing the propeller for easier future removal and corrosion prevention.
Performance Review: Speed, Handling, and Acceleration
The Rubex L3 Plus provides a significant upgrade in speed and responsiveness compared to factory-installed propellers. Boaters have reported faster acceleration from a stop (hole shot), smoother mid-range cruising, and improved fuel efficiency under load.
Thanks to its thick-blade design and aggressive cupping, this propeller shines in high-torque applications and remains stable even at top-end speeds. It’s compatible with popular outboard brands like Yamaha, Mercury, Evinrude, and Honda using the right Rubex hub kit.

Detailed FAQ Section
1. Is the Rubex L3 Plus (15.75 x 21″) compatible with my Yamaha outboard?
Yes, the Rubex L3 Plus is compatible with Yamaha outboards, provided you use the appropriate Rubex hub kit. Solas designs these propellers with adaptability in mind, and the interchangeable hub system allows fitment across different engine brands including Yamaha, Mercury, Honda, Evinrude, and Suzuki. Make sure to check your engine’s shaft size and spline count before purchasing the hub. This compatibility ensures a hassle-free installation and excellent performance on Yamaha-powered boats.
2. How does this stainless steel propeller compare to aluminum?
Stainless steel propellers like the Rubex L3 Plus are significantly more durable than aluminum. They withstand impact better, resist corrosion, and maintain their shape under stress, resulting in more precise performance. Aluminum is lighter and cheaper but tends to wear faster. If you’re serious about performance, fuel economy, and long-term reliability — especially in saltwater environments — stainless steel is the way to go.
3. Can I install the Rubex L3 Plus propeller myself?
Yes, installing the Rubex L3 Plus is manageable with basic tools and mechanical understanding. You’ll need a wrench, a torque tool, and marine grease. The interchangeable hub system simplifies the process. Always follow the engine manufacturer’s torque specifications and double-check blade clearance. If you’re unsure, it’s wise to consult a marine technician. Routine propeller maintenance is also recommended post-installation to ensure optimal operation.
4. What size boat is best for the Rubex L3 Plus (15.75 x 21″)?
This propeller suits mid to large-size boats that require higher pitch and strong grip, typically in the 18–25 foot range. It’s ideal for deep V hulls, sport fishing boats, and speedboats using outboard motors in the 150–300 HP range. Always factor in the load, elevation, and hull design when selecting a prop size — but this model offers a great balance of thrust and speed for general use.
5. How long does a stainless steel propeller like this last?
With proper care, stainless steel propellers like the Rubex L3 Plus can last over a decade. Durability depends on water conditions, frequency of use, and maintenance. Avoiding collisions with debris, cleaning after saltwater trips, and regular inspections will maximize its life. The investment in stainless steel pays off by reducing replacement frequency and offering consistent, peak performance year after year.
