Whether you’re navigating open waters or maneuvering tight channels, this propeller offers outstanding acceleration, top-end performance, and smooth cruising.
Its 4-blade design and precision-cast stainless steel construction allow for superior thrust and enhanced grip on the water, especially beneficial for heavier boats or applications requiring consistent power delivery. With a diameter of 15.25 inches and a pitch of 22 inches, the Rubex L4 LH Propeller is engineered to provide the perfect balance between power and efficiency.
Overview / What Is the Rubex L4 (15.25 x 22″) Solas LH Propeller?
The Rubex L4 9574-153-22 is a left-hand (LH) rotating, 4-blade stainless steel marine propeller designed for outboard engines. It belongs to the Rubex interchangeable hub system, meaning it offers flexibility and easy replacement compared to fixed-hub alternatives.
Key specifications include:
- Diameter: 15.25 inches
- Pitch: 22 inches
- Rotation: Left-hand (LH)
- Material: Stainless steel
- Hub system: Rubex interchangeable rubber hub
The Rubex L4 propeller is best suited for mid-to-high horsepower outboards and is especially favored in twin engine setups where one engine uses a left-hand and the other a right-hand rotating propeller to improve steering balance and performance.
Key Features That Make the Rubex L4 Propeller Stand Out
Choosing the right propeller can significantly impact your boat’s performance. The Rubex L4 LH Propeller offers:
- Enhanced Thrust & Grip: The 4-blade configuration offers better “bite” in the water, ensuring improved acceleration and holding power even in rough conditions.
- Built to Last: Made with premium-grade stainless steel, this propeller resists corrosion and damage from debris and saltwater exposure.
- Noise Reduction: The Rubex rubber hub design helps reduce vibration and noise, creating a smoother boating experience.
- Versatility: Compatible with a wide range of outboard engines including Yamaha, Honda, Mercury, Suzuki, and Evinrude (with appropriate hub kits).
In short, the Rubex L4 is designed to meet the needs of both performance enthusiasts and commercial operators who demand reliability on every trip.
Best Use Cases for the Rubex L4 (15.25 x 22″) Propeller
The Rubex L4 (15.25 x 22″) LH propeller is ideal for various boating styles:
- Fishing Boats: Provides better grip and efficiency when maneuvering at slow speeds.
- Sport Boats: Great for water sports due to strong acceleration and mid-range power.
- Twin Engine Setups: Balances thrust and handling when paired with a RH version.
- Heavy Hulls: Increased blade surface area improves handling in heavier or fully-loaded boats.
This propeller is an excellent choice if you’re looking to improve performance, fuel efficiency, and reliability all at once.
Maintenance Tips
Maintaining your Rubex L4 propeller ensures longevity and optimal performance throughout the boating season. Here are some essential maintenance tips:
- Inspect Before and After Use: Check for dents, cracks, or fishing line wrapped around the hub. These small issues can quickly turn into performance killers.
- Clean with Freshwater: Always rinse with freshwater after each trip, especially in saltwater environments, to prevent corrosion.
- Grease the Prop Shaft: Use marine-grade grease on the shaft during installation to prevent seizing.
- Check Torque Settings: Ensure your prop nut is properly torqued to factory specifications to avoid wobble or slippage.
- Use the Right Hub Kit: Pairing with a genuine Rubex hub kit ensures smooth and safe operation.
Following these practices will keep your Rubex L4 propeller marine in top-notch condition.

Detailed FAQ Section
What engines are compatible with the Rubex L4 (15.25 x 22″) Solas LH Propeller?
The Rubex L4 (15.25 x 22″) LH Propeller is compatible with various outboard engines including Yamaha, Suzuki, Mercury, Evinrude, Honda, and Johnson. However, it requires the correct Solas Rubex hub kit to match your specific engine shaft. The propeller’s modular hub system makes it adaptable to multiple engine types, enhancing its flexibility and value. Always confirm your engine’s shaft diameter, spline count, and rotation direction before purchasing. If you’re running a twin engine setup, pairing this LH propeller with a RH version like the 9573-153-22 offers optimal thrust balance and smoother steering control.
How do I choose the right pitch for my boat?
Choosing the correct pitch is crucial. The 22” pitch version of the Rubex L4 offers a good balance of top-end speed and mid-range torque. A higher pitch prop will give you more speed at lower RPMs but can decrease acceleration, while a lower pitch will increase acceleration at the cost of top speed. For heavier boats or those carrying frequent passengers, a 22″ pitch is often ideal. Consult your engine’s RPM range and boat manufacturer recommendations. If unsure, our support team can help evaluate your current prop’s performance and suggest the ideal Rubex L4 pitch.
How long does a Rubex L4 stainless propeller last?
Stainless steel propellers like the Rubex L4 typically last 5–10 years or more with proper maintenance. Compared to aluminum, they resist damage from debris and cavitation. Routine care such as flushing with freshwater, inspecting for fishing line, and greasing the shaft prolongs lifespan. The Rubex L4’s high-quality construction makes it suitable for both salt and freshwater use, with minimal degradation over time. With the interchangeable hub design, even if the rubber hub wears out, the propeller itself remains reusable — adding value over the long run.
What’s the difference between LH and RH propellers?
LH (Left-Hand) and RH (Right-Hand) refer to the direction the propeller rotates. Most single-engine boats use RH propellers. LH props are commonly used in twin engine setups to balance torque and improve steering. For example, in a twin engine configuration, one engine would use the LH Rubex L4 and the other a RH version to minimize side thrust. Installing the wrong rotation propeller can severely impact performance, so always verify your engine’s requirements or consult with a marine technician before purchase.
Is the Rubex L4 difficult to install?
Not at all. Thanks to the Solas Rubex interchangeable hub system, installing the Rubex L4 is straightforward. You’ll just need the appropriate Rubex hub kit for your engine. The hub slides into the propeller and onto the engine shaft, secured by a washer and nut. The system reduces vibration and is much easier to maintain or replace than traditional pressed hubs. For first-time installers, we recommend reviewing your engine’s manual and checking the torque specifications to ensure correct installation.
