How to Install the Rubex S3 Propeller Correctly
Installing the Rubex S3 Propeller is relatively simple if you follow the correct procedures. Always start by checking your owner’s manual and ensuring your engine is turned off with the key removed.
- Remove the old propeller by straightening and removing the cotter pin, washer, and nut.
- Slide off the old propeller and clean the shaft of any debris.
- Install the Rubex hub system (sold separately), aligning it properly.
- Place the new Rubex S3 propeller over the hub.
- Secure it with the provided washer and nut, tightening to recommended torque specs.
- Insert a new cotter pin to lock it in place.
Important: Use marine-grade grease on the shaft to prevent corrosion and make future removal easier.
Maintenance Tips
To ensure long-term performance and prevent premature wear, regular maintenance is crucial for your Rubex S3 propeller marine. Follow these tips:
- Rinse with Freshwater: After every saltwater outing, rinse the propeller thoroughly to remove salt buildup.
- Inspect for Damage: Check for dents, nicks, or bent blades which may affect performance and fuel efficiency.
- Re-Grease Shaft: Apply marine grease every 2–3 months or after heavy usage.
- Check Hub Wear: Inspect the hub for signs of fatigue or damage, especially if you feel vibration or slippage.
Routine care will extend the life of your investment and ensure optimal engine operation.

Detailed FAQ Section
Is the Rubex S3 Propeller compatible with all outboard engines?
No, while the Rubex S3 uses an interchangeable hub system, you must purchase the correct Rubex hub kit for your engine make. It supports major brands like Yamaha, Mercury, Evinrude, Suzuki, and Honda, but exact compatibility depends on your engine’s spline and shaft size. Always cross-reference the hub model to your engine’s specification or consult a marine expert to avoid mismatch issues. A compatible hub ensures smooth installation, vibration reduction, and torque delivery. Installing the wrong hub can result in slippage, inefficient power transfer, or even damage to your drivetrain. That said, Rubex hubs are affordable and designed to last, making this system extremely user-friendly.
What are the benefits of using stainless steel over aluminum propellers?
Stainless steel propellers like the Rubex S3 offer durability, strength, and performance advantages. Aluminum props are lighter and cheaper, but they tend to flex under stress, which reduces performance at high speeds. Stainless steel, on the other hand, resists flexing, offering sharper response, better acceleration, and enhanced fuel economy. It also lasts longer, especially in saltwater environments, due to its corrosion resistance. If you’re a serious boater or operate in tough marine conditions, the investment in stainless steel pays off over time through reduced maintenance and better performance. For those seeking reliability and efficiency, stainless steel is the go-to choice.
How do I know when to replace my Rubex S3 propeller?
Signs that indicate your Rubex S3 propeller needs replacing include visible cracks, bent blades, excessive vibration during operation, or a noticeable drop in performance (e.g., lower speed at full throttle). Also, if your boat struggles to plane or you’re burning more fuel, the propeller might be damaged or worn. Minor dings can be repaired, but major structural damage requires replacement. Regular inspections — especially after contact with debris or shallow ground — are essential. If you suspect performance loss, a propeller balancing test or consultation with a marine technician can confirm whether replacement is necessary. It’s always safer to replace than risk drivetrain damage.
Can I upgrade my current propeller to the Rubex S3 without changing anything else?
Yes, in most cases, the Rubex S3 can replace your current propeller as long as you have or purchase the correct Rubex hub kit. Since it uses a modular system, you don’t need to alter the shaft or make significant adjustments to your engine. Just ensure pitch and diameter are appropriate for your boat size and engine RPM range. For example, switching from a 19” to a 22” pitch will reduce RPM and potentially improve fuel efficiency. Always verify with your engine manufacturer’s RPM operating range and consult a prop expert if needed to make sure the switch doesn’t compromise performance.
How much does the Rubex S3 cost, and is it worth the price?
The price of the Rubex S3 (15.125 x 22″) Solas RH Propeller, 9561-151-22 typically ranges from $350–$420 depending on the retailer and hub inclusion. While it may seem more expensive than aluminum props, its longevity, strength, and performance gains justify the cost. Additionally, its modular hub system saves future costs on replacements. When you consider fuel savings, better acceleration, and lower maintenance, it offers strong ROI. Plus, AllBoatSupplies.com offers a 5% discount using code WELCOME5, making it even more affordable.
