Overview / What Is Rubex HR4 (14.125 x 18″) Solas LH Propeller?

The Rubex HR4 propeller is a four-blade, left-hand rotation propeller with a 14.125″ diameter and 18″ pitch. It is specifically designed to suit higher horsepower outboard motors and stern drives, delivering refined power curves, improved hole shot, and more responsive handling.

Constructed from high-grade stainless steel, the Rubex HR4 is part of the Solas Rubex 4 blade series and is known for its superior corrosion resistance and long-lasting durability. The interchangeable Rubex hub system further enhances its adaptability and reduces replacement costs. Perfect for boats requiring excellent mid-range cruise performance and acceleration, this model supports multi-purpose usage—fishing, cruising, and towing sports.

Why Choose a 4-Blade Stainless Steel Propeller?

The decision to upgrade from a 3-blade to a 4-blade propeller is often based on performance needs. A 4-blade prop like the Rubex HR4 provides enhanced stern lift, tighter turns at lower speeds, and better holding in rough waters. Here’s why the 4-blade stainless steel model is preferred:

• Faster Planing: The extra blade gives the boat quicker lift-off.
• Superior Grip: Holds tighter in sharp turns and turbulent waters.
• Reduced Vibration: Balanced design means smoother performance.
• Improved Fuel Economy: Efficient thrust at mid-range RPMs.

When paired with the high-quality stainless steel used in the Rubex HR4, you not only get performance but also long-term value.

Best Applications for Rubex HR4 (14.125 x 18″)

This propeller is ideal for mid-to-high horsepower engines—particularly 90HP to 200HP range outboards—used in:

• Center Console Fishing Boats
• Ski and Wake Boats
• Pontoon Boats
• Runabouts

Its precise hydrodynamic design ensures minimal cavitation, optimal power transfer, and balanced steering during both cruising and high-speed runs.

Maintenance Tips

Maintaining your Rubex HR4 propeller is crucial to prolong its life and sustain its top-tier performance. Here are essential maintenance tips:

• Rinse after every use: Especially after saltwater outings to prevent corrosion.
• Inspect the blades: Regularly check for dings, chips, or bent blades.
• Use anti-seize compound: On the shaft threads to prevent galling and ease removal.
• Grease the hub kit: Maintain the inner hub to prevent metal-on-metal friction.
• Remove propeller periodically: To clean fishing lines or debris wrapped around the shaft.

By following these simple maintenance protocols, your Rubex HR4 will deliver consistent power and reliability season after season.

Detailed FAQ Section

What engines are compatible with the Rubex HR4 (14.125 x 18″) Solas LH Propeller?

This propeller is compatible with a wide range of 90HP to 200HP outboard engines from manufacturers such as Yamaha, Honda, Mercury, Suzuki, and Evinrude. Its versatility is thanks to the interchangeable Rubex hub system, which adapts to different shaft sizes and splines. Always consult your engine’s manual or seek advice from a marine technician before purchase to confirm compatibility.

How do I install the Rubex HR4 propeller with the Rubex hub kit?

Installation is straightforward. Begin by removing the old prop and thoroughly cleaning the shaft. Slide the Rubex hub kit onto the shaft, followed by the Rubex HR4 propeller. Add the thrust washer, nut, and cotter pin as instructed. Always torque to your engine’s recommended specification. Installation should take under 15 minutes with basic tools.

What are the signs that my current propeller needs replacing?

If you notice decreased performance, slower acceleration, excessive vibration, or poor fuel economy, your current propeller may be damaged or improperly pitched. Visual signs like chipped, bent, or cracked blades are obvious indicators. Replacing it with a Rubex HR4 not only restores performance but also enhances efficiency.

How does the Rubex HR4 compare to aluminum propellers?

The Rubex HR4 offers superior strength, performance, and corrosion resistance compared to aluminum props. While aluminum may suffice for occasional or budget-conscious users, stainless steel delivers enhanced thrust, better responsiveness, and lasts significantly longer. It’s a cost-effective upgrade in the long term.

What is the pitch and diameter of this propeller, and why do they matter?

The Rubex HR4 has a pitch of 18″ and a diameter of 14.125″. Pitch affects how far your boat moves forward with each propeller rotation—higher pitch = higher top speed, but slower acceleration. Diameter impacts water displacement and thrust. The balance in this propeller ensures excellent all-around performance for mid-to-high HP engines.

Conclusion

The Rubex HR4 (14.125 x 18″) Solas LH Propeller, 9554-141-18 is more than just a propeller—it’s a performance upgrade designed to elevate your boating experience.
