Overview / What Is Rubex HR4 (13.25 x 15″) Solas LH Propeller, 9454-133-15?
The Rubex HR4 (13.25 x 15″) Solas LH Propeller is a high-performance, four-blade stainless steel propeller designed to fit a wide range of outboard and sterndrive engines. It features a 13.25-inch diameter and 15-inch pitch, and is designed with a left-hand rotation for specific marine propulsion systems. The Rubex HR4 is part of the Solas Rubex hub kit system, offering interchangeable hub functionality, reducing wear on your drivetrain and prop shaft while simplifying installation and replacement.
This propeller is ideal for heavier boats or vessels that operate in rough waters, thanks to its blade shape and cupping design, which provide more stern lift and better holding power in turns. Its stainless steel construction ensures high corrosion resistance, making it reliable in both freshwater and saltwater conditions. It is especially effective for boats equipped with V4 or V6 engines in the 90–225 HP range, depending on engine compatibility.
Key Features of the Rubex HR4 Propeller
Let’s take a closer look at what makes this propeller stand out:
- Quad-blade design for smoother handling and better mid-range fuel efficiency.
- Stainless steel construction for long-lasting durability and corrosion resistance.
- Interchangeable Rubex hub system – reduces shock and drivetrain damage.
- Left-hand rotation – perfect for counter-rotating setups or select engine types.
- Enhanced cupping to reduce ventilation and increase grip in rough water.
The Rubex HR4 is also well-regarded for its thrust output, especially when pulling skiers or cruising with heavy loads. It provides a significant upgrade over OEM aluminum or older three-blade designs.
Performance Advantages of a 4-Blade LH Propeller
Upgrading to a four-blade propeller like the Rubex HR4 (13.25 x 15″) Solas LH offers multiple performance benefits over traditional three-blade options. Most notable is the improved thrust and handling at low speeds, especially when docking or navigating narrow channels. Four blades provide greater surface area and load distribution, which leads to:
- Better grip in rough water
- Smoother acceleration and planing
- Reduced vibration and noise
- Improved fuel economy at cruising speeds
The left-hand rotation helps balance twin-engine setups and supports better maneuverability in reverse. It’s a popular configuration for dual outboard systems where one engine spins clockwise and the other counterclockwise to improve balance and stability.
Maintenance Tips
To extend the life and performance of your Rubex HR4 (13.25 x 15″) Solas LH Propeller, follow these expert maintenance tips:
- Inspect regularly – Check for dings, cracks, or bent blades after every trip, especially if navigating rocky or shallow waters.
- Clean after use – Rinse the propeller with fresh water and remove any weeds, fishing line, or debris that may have accumulated.
- Grease the shaft – Use marine-grade grease on the propeller shaft to prevent corrosion and ease future removal.
- Tighten properly – Torque the prop nut to manufacturer specifications to avoid vibration or hub damage.
- Use a Rubex hub kit – Ensure you are using the correct hub kit for your engine to reduce drivetrain wear.
By following these steps, you can maximize efficiency, reduce long-term costs, and ensure your propeller delivers top-tier performance season after season.

Detailed FAQ Section
What engines are compatible with the Rubex HR4 (13.25 x 15″) Solas LH Propeller?
This propeller is compatible with a variety of outboard and sterndrive engines, especially from major manufacturers like Yamaha, Mercury, Evinrude, Suzuki, and Honda, depending on the correct Rubex hub kit. Typically, it is ideal for 90HP to 225HP engines with left-hand rotation. Always cross-reference your engine’s shaft specifications with Solas’s fitment guide or consult with a marine professional before purchasing.
Is the Rubex HR4 stainless steel propeller better than aluminum?
Yes. The Rubex HR4’s stainless steel construction offers better strength, durability, and resistance to cavitation compared to aluminum props. Stainless steel can handle higher horsepower and torque levels without flexing under pressure, resulting in more accurate and efficient propulsion. Although aluminum is less expensive upfront, stainless steel like the HR4 provides better long-term performance and reliability in both freshwater and saltwater environments.
How often should I inspect or replace my Rubex HR4 propeller?
You should inspect your propeller after every few outings, particularly if you’ve been in shallow, debris-filled, or rocky waters. Small chips or dents can lead to imbalance and performance issues. Under normal conditions and with proper care, the Rubex HR4 can last for many seasons. However, it’s best to replace the propeller if you notice consistent vibration, reduced performance, or visible structural damage.
Can I install this propeller myself or do I need a professional?
Installation is relatively simple and can be done by any boater with basic tools and a bit of mechanical knowledge. The Rubex HR4 system is designed for DIY installation using the Rubex interchangeable hub kits. Just follow the step-by-step guide provided with your hub, use proper torque settings, and always check for proper fit and rotation. If unsure, it’s always wise to consult a certified marine technician for installation assistance.
What’s the difference between left-hand and right-hand propellers?
The difference lies in the direction the propeller spins when viewed from the rear. A left-hand (LH) propeller spins counterclockwise and is often used in dual-engine setups to counterbalance a right-hand (RH) propeller, improving vessel handling and reducing steering torque. The Rubex HR4 (13.25 x 15″) Solas LH Propeller is ideal for counter-rotating engines or specific stern-drive applications that require left-hand operation.
Conclusion
The Rubex HR4 (13.25 x 15″) Solas LH Propeller, 9454-133-15 stands out as a reliable and high-performance propeller ideal for boating enthusiasts who want enhanced control, better fuel economy, and long-term durability. With its stainless steel build, left-hand rotation, and four-blade design, it offers advantages across a range of conditions and vessel types. Whether you’re cruising, fishing, or waterskiing, upgrading to the Rubex HR4 ensures smooth, powerful, and efficient marine propulsion. Don’t settle for average performance — make every outing memorable with this advanced Solas propeller.
