Overview / What Is Rubex NS3 (13 x 19″) Solas LH Propeller?

The Rubex NS3 (13 x 19″) Solas LH Propeller is a premium marine-grade stainless steel prop designed to provide balanced acceleration, top-end speed, and enhanced mid-range fuel economy. It’s ideal for boats powered by outboard engines in the 90–140 HP range requiring left-hand rotation. This propeller’s 19″ pitch offers greater thrust and RPM control, helping you reach cruising speed quickly while conserving fuel during extended operation.

Made with precision craftsmanship and backed by Solas’s reputation for marine propulsion excellence, this model is compatible with the Rubex interchangeable hub system. It’s suited for use in saltwater or freshwater, ensuring longevity even in corrosive environments.

How to Install Rubex NS3 LH Propeller

Wondering how to install the Rubex NS3 LH propeller for marine use? The installation process is straightforward. Begin by removing the current propeller and inspecting the propeller shaft. Slide in the compatible Rubex hub (sold separately), ensuring it aligns with the engine’s splines. Once the hub is inserted into the propeller housing, install the unit onto the shaft, align everything, and tighten the locking hardware to manufacturer torque specifications.

Don’t forget to apply marine-grade grease to the shaft before installation. This prevents rusting and makes future removal easier. Always double-check that the propeller rotates correctly in the left-hand direction before operating.

Performance & Efficiency: What to Expect from the 13 x 19” Pitch

The 13 x 19” pitch strikes a great balance between fuel efficiency and speed. It is ideal for boaters who value fast cruising, stable acceleration, and the ability to maintain plane under load. With the Rubex NS3 LH propeller for marine applications, you can expect reduced cavitation and smooth operation even during sharp turns or choppy waters.

This propeller is ideal for:

• Saltwater fishing boats that require durability and power
• Recreational cruisers looking for smooth mid-speed handling
• Dual engine setups using left-hand propeller configurations

How to Troubleshoot Rubex NS3 LH Propeller Performance Issues

If your boat experiences unexpected vibration, poor acceleration, or excessive RPMs, you may need to inspect your propeller. Check for bent blades, marine growth, or damage to the rubber hub. One of the most common issues is hub slippage, which can be resolved by replacing the Rubex insert. Also, ensure the prop is torqued properly and aligned with the engine shaft.

If the boat struggles to reach planing speed or over-revs at full throttle, the 19” pitch may be too aggressive for your setup. Consider dropping to a 17” pitch for more bottom-end power, especially for heavier boats or water sports applications. Conversely, if you’re under-revving, the 13 x 19” pitch might be perfect to regain balance.

Maintenance Tips

Maintaining your Rubex NS3 LH Propeller ensures consistent performance and protects your investment. Rinse with fresh water after each trip—especially in saltwater—to prevent corrosion buildup. Inspect blades for nicks, dents, or fishing line debris that could lead to cavitation damage.

Every few months, remove the propeller to check the condition of the rubber hub and the prop shaft. Clean off marine growth and apply a fresh layer of waterproof grease to prevent seizing. Replace the hub if there are signs of excessive wear or vibration during use. Always store your boat in neutral with the prop lifted when trailering or docked for extended periods.

Expert Advice and Pro Recommendations

Marine professionals consistently recommend the Rubex NS3 (13 x 19″) Solas LH Propeller, 9432-130-19 for boats with 90–140 HP engines that prioritize a balance of performance and efficiency.

Detailed FAQ Section

What are the benefits of using a 13 x 19” LH stainless steel propeller?

The primary benefit of a stainless steel 13 x 19” LH propeller like the Rubex NS3 is improved durability and precision handling. Stainless steel resists flexing, so the blades retain shape even under heavy loads. A 19” pitch is perfect for faster cruising and fuel savings. LH rotation supports dual-engine configurations or engines specifically designed for counterclockwise rotation. The result is improved grip, thrust, and reduced cavitation in all conditions.

How do I know if my outboard supports left-hand rotation?

You can determine your engine’s propeller rotation direction by checking the existing propeller or engine manual. A LH (left-hand) propeller spins counterclockwise when viewed from behind the boat. Twin-engine boats often use one LH and one RH propeller to balance torque. If your previous propeller has the marking “LH” or your boat accelerates slightly to the right under throttle, you’re likely using or need an LH model like the Rubex NS3 (13 x 19”).

What is the ideal horsepower range for this Rubex NS3 (13 x 19″) LH Propeller?

The ideal engine range for this propeller is between 90 to 140 horsepower. Most mid-sized outboard motors from Yamaha, Mercury, Evinrude, and Honda will support this pitch and diameter. However, it’s important to match the spline count and rotation direction when selecting a propeller. Also, check your boat’s max RPM recommendation to avoid under- or over-propping.

Can I replace the hub in this propeller?

Yes. One of the advantages of the Rubex system is its removable hub. The propeller is designed to work with Rubex rubber hubs, which absorb shock and reduce noise. If you notice vibration, slippage, or rubber deterioration, simply replace the hub with a compatible Rubex model. This modularity extends the life of your propeller and makes future pitch upgrades more cost-effective.

What makes the Rubex NS3 (13 x 19”) LH Propeller good for saltwater use?

This propeller is built from marine-grade stainless steel, which resists rust, corrosion, and blade fatigue common in saltwater environments. Its highly polished finish further protects against saltwater damage. Combined with proper maintenance and fresh water rinsing after use, the Rubex NS3 LH propeller will perform reliably in saltwater conditions for many seasons.

Conclusion

The Rubex NS3 (13 x 19″) Solas LH Propeller, 9432-130-19 is a performance-focused, stainless steel upgrade perfect for mid-range outboard engines. With its efficient 19” pitch, durable marine construction, and vibration-reducing Rubex hub compatibility, it delivers a complete propulsion solution. Whether you’re a recreational boater or professional angler, this propeller ensures smoother, faster, and more fuel-efficient rides every time.
