Overview / What Is the Rubex NS3 (13.75 x 13″) Solas LH Propeller?
The Rubex NS3 LH 9432-138-13 is a stainless steel, 3-blade propeller designed for left-hand rotation, making it a powerful match for dual-engine boats or specific single-outboard setups that require LH rotation. The dimensions—13.75-inch diameter with a 13-inch pitch—offer a fine balance between top-end speed and low-end torque, making it a versatile choice for recreational boaters and professionals alike.
Manufactured by Solas, this propeller incorporates the company’s advanced casting techniques and quality assurance processes. The result is a high-strength, corrosion-resistant propeller with impressive hydrodynamic performance. What truly sets the NS3 series apart is its ability to maintain pitch accuracy under high loads, giving your vessel consistent thrust and smoother ride quality.
Why Choose a Left-Hand Rotation Propeller?
Boaters often ask whether they need a left-hand (LH) or right-hand (RH) propeller. LH propellers like the Rubex NS3 9432-138-13 rotate counterclockwise when viewed from the rear. They’re ideal for dual-engine boats where engines rotate in opposite directions to balance torque and improve handling.
Using an LH propeller can also reduce torque steer and allow better tracking in certain hull configurations. The NS3 LH is specifically optimized for such uses, ensuring your boat handles efficiently even under challenging load and wave conditions.

Rubex NS3 Stainless Steel: A Performance Breakthrough
The Rubex NS3 LH (13.75 x 13″) is more than just a propeller—it’s a performance upgrade. Compared to aluminum counterparts, stainless steel propellers like the NS3 exhibit greater rigidity, which translates into better acceleration, higher top speeds, and more accurate maneuvering.
What makes the NS3 particularly impressive is its compatibility with a wide range of outboard motors from brands like Yamaha, Mercury, Suzuki, and Honda. Its universal fit and advanced geometry allow it to deliver consistent performance across varying RPM ranges and engine loads.
Maintenance Tips
To ensure the longevity of your Rubex NS3 LH propeller, follow these maintenance best practices:
- Rinse After Use: Always rinse the propeller with freshwater after use in saltwater to prevent corrosion buildup.
- Inspect Regularly: Check for cracks, dings, or fishing line around the shaft hub every 10-15 hours of use.
- Grease the Shaft: Apply marine-grade grease on the propeller shaft before installation to avoid seizing and corrosion.
- Use the Right Tools: Torque the propeller nut to manufacturer specifications to avoid vibration and performance loss.
Following these tips can extend the life of your propeller and improve overall engine performance.

Detailed FAQ Section
What type of boats is the Rubex NS3 (13.75 x 13″) LH propeller best suited for?
This propeller is best suited for mid-size recreational boats, fishing boats, and sport boats requiring a left-hand rotation. Its size and pitch make it ideal for engines ranging between 90–150 HP. The left-hand design is especially helpful for twin-engine setups that require opposite rotations for balanced performance and torque management.
How does stainless steel improve performance over aluminum propellers?
Stainless steel offers superior rigidity compared to aluminum, which minimizes blade flexing under load. This results in improved acceleration, faster planing, better cornering, and more efficient fuel usage. The Rubex NS3 LH also handles rough water better and provides consistent thrust even at higher RPMs.
Can I install the Rubex NS3 LH propeller myself?
Yes, the Rubex NS3 propeller is designed for easy DIY installation. It uses a replaceable hub system that’s compatible with most outboard engines. Simply follow the included installation instructions or your outboard manufacturer’s guidelines. Basic hand tools and marine grease are all that’s needed for installation.
What is the cost and durability of the Rubex NS3 LH propeller?
While stainless steel propellers like the NS3 are more expensive than aluminum ones, their durability and performance justify the price. The Rubex NS3 LH typically lasts 3–5 times longer, especially in saltwater environments. With proper maintenance, it offers excellent long-term value and reduced replacement frequency.
How often should I inspect or replace the propeller?
Inspect your propeller every 15–20 hours of use or after every trip through shallow or debris-filled waters. Check for dings, chips, and fishing line entanglement. If performance drops or vibration increases, you may need a professional inspection or balancing. Replacement is usually only necessary after visible damage or several seasons of use.
