Overview / What Is the Rubex HR4 (13 x 19″) Solas LH Propeller?
The Rubex HR4 (13 x 19″) Solas LH Propeller, 9454-130-19 is a premium stainless steel 4-blade propeller developed by Solas, one of the most respected names in marine propulsion. Engineered with high-rake and cupped blade geometry, this left-hand rotating propeller ensures strong acceleration, superior midrange performance, and outstanding fuel efficiency. It’s compatible with various outboard motors and is particularly suited for heavier boats that require extra grip and torque.
This propeller belongs to the Rubex 4 series, which uses interchangeable Rubex hub kits to reduce vibration and enhance durability. These hub kits also protect your engine by absorbing shock during high-impact situations such as hitting submerged objects. With dimensions of 13” diameter by 19” pitch, this LH (left-hand) rotating propeller provides a balanced trade-off between hole shot and top speed.

Performance Benefits of a 4-Blade LH Stainless Propeller
Unlike traditional 3-blade props, 4-blade propellers like the Rubex HR4 (13 x 19″) deliver superior thrust at low speeds, ideal for watersports, fishing, and heavy-load boating. The extra blade enhances bite in the water, meaning better handling and reduced cavitation.
The left-hand (LH) rotation makes it a perfect match for twin-engine setups or specific outboards that demand counter-rotation. This balance enhances control in turns and provides a more stable ride in turbulent water.
How to Install the Rubex HR4 (13 x 19″) Solas LH Propeller
Installing your new Rubex HR4 propeller is a straightforward process thanks to the Rubex interchangeable hub system. Follow these steps:
- Remove the cotter pin and old propeller from your outboard engine shaft.
- Slide the Rubex hub into the new HR4 propeller.
- Install the propeller onto the shaft, followed by thrust washer, spacer, and nut.
- Tighten securely and reinstall the cotter pin.
Tip: Always use marine-grade grease on the shaft and double-check torque specifications for your engine brand.
Maintenance Tips
To ensure long-term performance and reduce the risk of corrosion, proper maintenance of your Rubex HR4 (13 x 19″) Solas LH Propeller is essential. Here are a few proven practices:
- Rinse after each use: Especially in saltwater, thoroughly rinse the propeller and lower unit with freshwater.
- Inspect regularly: Check for fishing line entanglement or damage on the blades that could cause vibration.
- Grease the shaft: Every 20–30 hours of use, remove the propeller and apply marine grease to prevent rust and seizing.
- Check the hub: Periodically inspect the Rubex hub for wear and replace if it shows signs of damage or slippage.
Proper maintenance increases efficiency and saves money by preventing early wear on your engine’s drivetrain.
Rubex HR4 9454-130-19 vs Other Stainless Steel Propellers
Compared to other stainless steel props in the 13×19 category, the Rubex HR4 stands out due to its advanced cupping and 4-blade construction. Many traditional props in this size are 3-blade, which sacrifices control in exchange for top-end speed. The HR4 is tuned for balance, making it a better all-rounder for boats carrying passengers, towing wakeboarders, or fishing offshore.
Additionally, Rubex’s unique interchangeable hub system gives it a huge advantage in terms of cost efficiency and protection. If your boat strikes an object, replacing the hub is much cheaper than buying a new propeller. That makes the HR4 not just a high-performance choice, but also a smart long-term investment.
Expert Advice and Pro Recommendations
If you’re looking for the best stainless steel propeller for mid-sized boats, the Rubex HR4 (13 x 19″) LH propeller is hard to beat. Its 4-blade configuration ensures consistent performance, especially when the boat is loaded or facing rough water. The cupping also helps reduce prop slip and improves fuel efficiency.
Pro boaters recommend pairing this prop with the correct Rubex hub kit for your engine and conducting a test run under typical boating conditions to fine-tune performance. It’s also wise to keep a backup prop or hub on hand during long trips.

Detailed FAQ Section
What type of boat is best suited for the Rubex HR4 13 x 19 LH propeller?
The Rubex HR4 9454-130-19 is ideal for mid-sized boats, including center consoles, dual consoles, walkarounds, and pontoon boats that demand extra thrust and stability. It’s particularly effective for vessels that carry additional weight such as fishing gear, coolers, and multiple passengers. Due to its 4-blade design and left-hand rotation, it’s also great for twin-engine applications where counter-rotating props are essential. The enhanced grip makes it suitable for watersports or offshore boating where control and acceleration are more important than outright speed.
How does the Rubex HR4 compare to a 3-blade propeller?
The main difference is that 4-blade props like the Rubex HR4 provide better low-end power, smoother rides, and increased handling — particularly in rough conditions or when making tight turns. A 3-blade propeller may offer slightly higher top speed, but often sacrifices grip and hole-shot power. If you value responsiveness, especially under load, the Rubex HR4 is the superior choice. It also delivers better fuel economy in many midrange throttle scenarios, making it a great option for all-day cruising and fishing trips.
Is it easy to install the Rubex HR4 9454-130-19?
Yes, installation is user-friendly, especially with the Rubex interchangeable hub system. Most boaters can complete the installation in under 15 minutes with basic tools. Always refer to your engine’s user manual for specific torque requirements and use a marine-grade prop wrench. The hub system not only simplifies setup but also protects the propeller and engine shaft from impact damage, making this a DIY-friendly and cost-saving feature.
What maintenance does the Rubex HR4 require?
Basic care includes regular freshwater rinsing after saltwater use, shaft greasing every few outings, and visual inspection of the blades and hub. If your boat vibrates unusually or loses speed, remove and inspect the propeller for damage or fishing line. Stainless steel is corrosion-resistant, but buildup from marine life or salt can still affect performance. Grease the prop shaft and inspect the hub every 20–30 hours of boating to maintain optimal function.
What is the lifespan and warranty of the Rubex HR4?
With proper care, the Rubex HR4 can last several boating seasons or longer. Its stainless steel construction resists wear, corrosion, and impact damage. The Rubex HR4 comes with Solas’ standard warranty, which covers manufacturer defects. For most users, the investment pays off over time with increased fuel efficiency, fewer replacements, and smoother operation. Always check the specific warranty terms at the point of purchase, and register the product online for full coverage.
