How to Install the Rubex 3 Propeller
Installing the Rubex 3 (10.3 x 12″) Solas RH Propeller is simple, thanks to its hub kit compatibility and straightforward mounting system. Here’s a step-by-step guide:
- Ensure your engine is off and safely lifted out of the water.
- Remove the existing propeller by unscrewing the prop nut and any washers or spacers.
- Clean the prop shaft to remove any corrosion or debris.
- Install the Rubex rubber hub (sold separately if needed) onto the propeller.
- Slide the propeller onto the shaft and secure it using the original hardware.
- Tighten the prop nut to the recommended torque specification and reinsert the cotter pin.
This process takes about 10–15 minutes for most DIYers and ensures proper fit and safe performance on the water.
Maintenance Tips
To ensure your Rubex 3 propeller lasts for many seasons, regular maintenance is crucial. Aluminum propellers are durable, but they still require attention, especially after heavy use or saltwater exposure.
- Rinse After Use: Always rinse the propeller with fresh water after saltwater use to prevent corrosion buildup.
- Inspect for Damage: Regularly check for nicks, dings, or bends in the blades. Even minor damage can affect performance and fuel efficiency.
- Lubricate Shaft: Apply marine grease to the propeller shaft before installation to prevent seizing and facilitate future removal.
- Check Hub Alignment: Misaligned hubs can cause vibrations. Ensure the rubber hub is centered and snug during installation.
Routine inspections and cleanings can significantly extend your propeller’s life and help maintain optimal engine health.
Top Benefits of Using a 10.3 x 12″ Pitch Propeller

Detailed FAQ Section
What boats are compatible with the Rubex 3 (10.3 x 12″) Solas RH Propeller?
This propeller is compatible with a variety of outboard motors in the 40HP to 70HP range. It works particularly well with brands such as Yamaha, Mercury, Honda, Evinrude, and Suzuki, provided they use the Rubex hub system. Always verify the shaft diameter and spline count before purchase to ensure compatibility.
Is aluminum better than stainless steel for propellers?
Aluminum propellers like the Rubex 3 offer a more affordable option for most recreational boaters. While stainless steel is stronger and better for high-performance applications, aluminum is easier to repair, lighter in weight, and provides more flexibility. The squeeze-cast process used by Solas significantly narrows the performance gap between the two materials.
How do I know if I need a 12” pitch propeller?
The correct pitch depends on your boat’s engine and your desired performance. A 12” pitch prop is ideal for mid-range acceleration and top speed for engines between 40–70HP. If your engine over-revs or struggles to plane, it may be worth adjusting pitch up or down. Consult your manual or a marine technician for specific RPM guidelines.
Can I install this propeller myself?
Yes, installation is straightforward. You’ll need a wrench, some marine grease, and optionally a new cotter pin. The Rubex system makes it easy to install or switch props using interchangeable hub kits. Many boaters find they can complete the job in under 20 minutes without any special tools or prior experience.
How often should I replace my boat propeller?
Replacement intervals depend on usage, but most aluminum propellers last several seasons with proper care. Signs that it’s time to replace include visible blade damage, excessive vibration, or reduced speed/fuel efficiency. It’s also wise to upgrade your propeller if you’re making changes to your boating activities — such as towing or cruising longer distances — that demand a different performance profile.
Conclusion
The Rubex 3 (10.3 x 12″) Solas RH Propeller offers the perfect mix of durability, affordability, and performance. Its design maximizes thrust, improves fuel efficiency, and ensures smooth handling — all essential for recreational boating. Backed by Solas’ reputation for quality, this propeller is a smart investment for any outboard owner in the 40–70HP range.
