Performance & Compatibility
The Rubex NS3 (13.75 x 13″) Solas LH Propeller performs exceptionally with mid‑range outboard engines—typically between 90 HP and 150 HP—depending on hull and load. Its left‑hand rotation makes it ideal for twin‑engine craft or specialized single‑engine configurations requiring reverse thrust or torque balancing.
This model is compatible with popular engine brands like Yamaha, Suzuki, Mercury, and Honda when paired with the correct Rubex hub kit. It works especially well for small to medium center consoles, bass boats, and displacement hulls needing controlled acceleration and top‑end speed.
How to Choose the Best Rubex NS3 Options for Your Boat
Selecting the right Rubex NS3 propeller involves evaluating your engine specs, boating style, and performance goals. Here are considerations:
- Engine horsepower and gearcase type
- Boat hull design—planing vs displacement
- Typical load and cruising speed
- Rotation direction requirement (single vs twin engine)
If you prioritize quick hole shot and mid‑range acceleration, a slightly lower pitch within the NS3 line may suit. For faster cruising, a higher pitch improves top speed efficiently.

The upfront cost of the Rubex NS3 stainless steel propeller is higher than aluminum alternatives—but it pays off over time. Stainless construction resists corrosion, withstands debris contact better, and retains blade geometry longer.
With proper maintenance and correct hub management, this propeller can last multiple boating seasons with minimal performance degradation. It’s a smart investment for boaters who value durability, efficiency, and peace of mind.
Detailed FAQ Section
What hulls and engines work best with the Rubex NS3 (13.75 x 13″) LH propeller?
This model is ideal for small to medium center consoles, bass boats, and lightweight displacement hulls paired with 90–150 HP outboards. It fits engines like Yamaha, Mercury, Suzuki, Honda, provided the correct Rubex hub kit is installed. The left‑hand rotation suits twin‑sub installations or special rig setups. Ensure your gearcase spline count matches the hub and verify fitment charts before purchase. This prop is optimized for smooth acceleration, decent top speed, and fuel economy—especially helpful for anglers or recreational boaters.
How to install the Rubex NS3 9432‑138‑13 prop safely and correctly?
Installation begins with removing the old prop and inspecting the shaft and gearcase. Choose the appropriate Rubex hub kit per your spline count. Apply marine‑grade grease, slide on the hub insert, then the propeller. Secure with washer, nut, cotter pin; torque to OEM spec. Check rotation direction—verify LH rotation when viewed from stern. Misinstallation can lead to vibration, slippage, or thrust loss. Always refer to engine manufacturer instructions and consider professional installation if unsure.
What maintenance schedule should I follow for optimal longevity?
Rinse the prop after each use if operating in saltwater. Before each trip, try spin the prop manually to inspect movement within the hub. After every few trips, lubricate the shaft. At season’s end, remove the propeller, dry it, apply anti‑corrosion spray, and store in a dry place. Replace hub insert if signs of wear or play occur. Bent blades or heavy corrosion warrant replacement. Following these Rubex NS3 maintenance tips extends lifespan and ensures peak performance.
How to troubleshoot decrease in speed or handling issues?
First, rinse prop and inspect for damage—dinged or bent blades reduce thrust. Next, check hub splines and insert for wear; slipping blades reduce acceleration. Confirm correct pitch/diameter—lower pitch increases hole shot but limits top end. Investigate misalignments—shaft wobble or improper installation torque can cause vibration. Consult prop fit chart to confirm proper selection. Regular assessment prevents minor issues from escalating into costly repairs.
How does the price of Rubex NS3 compare to other propellers in cost and durability?
The Rubex NS3 stainless steel propeller costs more than aluminum models upfront, but durability and performance give long‑term value. Stainless steel resists corrosion, stays true to shape, and handles debris impact better. The interchangeable hub system allows only hub insert replacement after wear, reducing whole‑prop costs. Over time, fewer replacements and better fuel efficiency offset initial price. Boaters who value high performance, less downtime, and consistent thrust find the Rubex NS3 worth the investment.
Conclusion
The Rubex NS3 (13.75 x 13″) Solas LH Propeller, model 9432‑138‑13, is a solid choice for boaters seeking durable, efficient, and precise marine propulsion. Its stainless steel construction, polished blade design, and interchangeable hub system deliver long‑term value and high performance. Whether for saltwater fishing or recreational cruising, the Rubex NS3 marine propeller offers reliable thrust and ease of maintenance.
