How to Install Rubex 3 Propeller Correctly
Proper installation ensures optimal performance and longevity of your Rubex 3 propeller. Always refer to your engine’s manual before installing any aftermarket component. Here’s a simplified installation guide:
- Start by disconnecting the spark plug wire to avoid accidental ignition.
- Remove the existing propeller by removing the cotter pin and nut.
- Install the appropriate Rubex hub kit into the new propeller.
- Slide the new propeller onto the shaft.
- Secure with the propeller nut and washer, then insert a new cotter pin.
Regularly check the torque on the nut, and inspect for fishing lines or debris around the shaft. Proper lubrication of the shaft can prevent future corrosion and sticking.
Rubex 3 Propeller Cost and Durability
Compared to stainless steel props, the Rubex 3 aluminum version offers an affordable yet reliable alternative. It is ideal for most recreational boaters who want dependable performance without the high cost. Priced competitively, it is often found between $80 and $120 depending on retailer promotions.
The durability of this propeller is impressive for its price point. Thanks to its powder-coated aluminum construction, it resists saltwater corrosion, cavitation burns, and minor impacts. However, aluminum does wear faster than stainless steel under extreme use, so inspection after every season is highly recommended.
Maintenance Tips
Maintaining your Rubex 3 propeller is essential for performance and longevity. Follow these tips to get the most out of your marine engine’s propulsion system:
- Inspect after every trip: Check for dings, cracks, or fishing line wrapped around the shaft.
- Clean thoroughly: Remove salt and algae with freshwater after use, especially in saltwater conditions.
- Lubricate the shaft: Apply marine-grade grease to the propeller shaft during installation or removal.
- Check the hub: Make sure the rubber hub isn’t worn or slipping. Replace it if needed.
- Store properly: Keep the propeller dry and in a padded case during the off-season.
Routine care goes a long way in preventing expensive repairs or replacements down the line.

Detailed FAQ Section
What makes the Rubex 3 propeller better than standard aluminum props?
The Rubex 3 propeller stands out due to its interchangeable hub system and optimized blade geometry. While many aluminum props offer basic performance, the Rubex 3 enhances acceleration and fuel economy thanks to its precision engineering. Additionally, it reduces vibration and potential engine damage during impacts. The powder-coated aluminum also holds up better in corrosive marine environments, making it ideal for saltwater and freshwater use alike.
How do I know if the Rubex 3 will fit my engine?
The Rubex 3 (12.1 x 9″) Solas RH Propeller is compatible with many engine brands, including Yamaha, Mercury, Suzuki, and Honda, provided you use the correct Rubex hub kit. You can check the Solas Prop Finder or contact a marine technician. Engine compatibility depends on your outboard’s horsepower, spline count, and shaft size. Always verify the model number, or ask for help at checkout to avoid mismatches.
Can I replace the Rubex 3 propeller myself?
Yes, replacing the Rubex 3 propeller is a straightforward DIY task if you have basic tools. You’ll need a wrench, marine grease, and possibly a cotter pin. The Rubex system’s interchangeable hub makes installation safer and easier, even for beginners. Still, ensure you follow the installation guide or manufacturer manual to avoid installation errors that may lead to vibration or slippage during operation.
Is the Rubex 3 suitable for saltwater use?
Absolutely. The Rubex 3 Solas RH Propeller is designed to withstand the corrosive effects of saltwater. Its high-quality aluminum and powder-coated finish resist oxidation and pitting. For optimal performance, it’s still recommended to rinse the propeller with freshwater after every saltwater trip and apply marine grease during installation to prevent shaft corrosion.
What should I do if my Rubex 3 propeller is vibrating?
Vibration in a propeller may stem from a few issues. First, inspect the blades for bends, chips, or cracks. Even minor damage can cause imbalance. Secondly, check if the hub is worn or incorrectly installed. A slipping hub will reduce power and cause unusual vibrations. Finally, ensure there is no debris wrapped around the prop shaft. If unsure, have a marine mechanic inspect it before continued use, as prolonged vibration may damage the drive train.
Conclusion
The Rubex 3 (12.1 x 9″) Solas RH Propeller is a high-performance, affordable aluminum propeller ideal for a wide range of marine engines.
