How to Install Rubex 3 (9.9 x 13″) Propeller
Installing the Rubex 3 propeller marine model is straightforward, even for first‑time installers. Before you begin, gather your hub kit (engine‑specific Rubex kit), thrust washer, nut, cotter pin or locking tab tool, and marine grease.
Installation steps:
- Remove the old propeller using a prop wrench and inspect shaft for damage or lines.
- Grease the splined shaft and thrust washer with marine‑grade grease.
- Insert the correct Rubex rubber hub into the propeller hub cavity.
- Slide the propeller onto the shaft, add thrust washer and tighten nut to manufacturer torque specs (usually ~55 ft‑lbs).
- Install cotter pin or locking tab. Ensure everything is secured.
Once installed, test boat running behavior and RPM range. The proper pitch should allow engine to reach optimal WOT RPM. If your engine can’t reach WOT range, consider lower pitch. If it over‑spools beyond recommendations, step up pitch.
Maintenance Tips
Regular maintenance of your Rubex 3 propeller marine model ensures long life and consistent performance. Follow these proven maintenance tips:
- Rinse with fresh water: After each saltwater outing, flush propeller to prevent corrosion.
- Inspect blades: Check for dings, dents, or bends that may affect balance.
- Lubricate internal hub: During seasonal removals, pack hub with marine grease.
- Check blades alignment: Misaligned blades can cause vibration and lower efficiency.
Proper seasonal storage includes removing the propeller, cleaning it thoroughly, and storing in a dry, safe place. With this care plan, the Rubex 3 can serve reliably for multiple boating seasons.
Performance Comparison: Pitch 12″ vs 13″
One common question: should you choose the 9.9 x 12″ or the 9.9 x 13″? The difference lies in performance and engine RPM tuning. The 12″ pitch gives quicker hole shots and better low‑end thrust. The 13″ pitch trades slightly slower acceleration for better hull speed and fuel economy.
If you frequently cruise at moderate to high speeds in open water, the 13‑inch pitch is often more suitable. But if you operate in shallow or tight water requiring rapid response, the 12‑inch may feel snappier. Engine RPM tuning is key: the 13‑inch should still allow you to hit the WOT RPM range specified by your engine maker.
Expert Advice and Pro Recommendations
Marine experts highlight the Rubex 3 (9.9 x 13″) as a solid upgrade for boaters wanting more efficiency and higher cruise speed. Technicians advise matching engine WOT RPM with propeller pitch—improper matching can harm performance and fuel economy.
Additional expert tips:
- Always pair with correct engine‑specific hub kit from Solas.
- Monitor WOT RPM after installation; aim to be within ± 150 RPM of engine’s target range.
- Replace rubber hub elements periodically based on use.

Detailed FAQ Section
What engines work with the Rubex 3 (9.9 x 13″) Solas propeller?
This propeller is compatible with many outboard engines between about 25 and 70 horsepower from major brands including Yamaha, Mercury, Suzuki, Evinrude, Johnson, and Tohatsu, provided the correct Solas Rubex hub kit is used. The interchangeable hub system ensures seamless compatibility by matching shaft spline count and alignment. When ordering, confirm your engine’s model year and spline count to receive the correct hub kit. Without the right hub kit, the prop may slip, vibrate, or damage your lower unit. Professional installers recommend confirming fit with manufacturer charts before purchase.
Compatibility is critical: the Rubex 3 propeller marine line reduces the risk of mismatched propellers by offering clear hub kit options. Always verify your engine’s spline configuration—commonly 13 , 15 or 18 tooth spline sets—and choose the correct part number.
How do I choose the right pitch: 13″ vs 12″?
The decision between the 9.9 x 12″ and 9.9 x 13″ pitch depends on your boat’s performance needs. The 12″ pitch gives quicker acceleration and better response, ideal for tight water or getting on plane quickly. The 13″ pitch, on the other hand, raises eventual hull speed and improves cruise RPM efficiency. When selecting, consider your typical RPM range at WOT. Engines usually specify an optimal RPM band—if using the 13″ pitch prevents reaching that band, you may need to revert to 12″ or select a lower pitch option.
Real‑world users report that the Rubex 3 (9.9 x 13″) helps reduce fuel burn on longer runs and maintains stable RPMs in moderate chop. Meanwhile, some anglers in heavy shallows report better performance with 12″, as lower pitch helps avoid stalling when throttling through vegetation or shallow dirt surfaces.
What maintenance routines support propeller longevity?
The top maintenance tips for the Rubex 3 propeller marine model include rinsing after each saltwater use, greasing the hub during reinstallation or seasonal storage, and inspecting blades for damage or warping. Small dings or bends should be fixed promptly—imbalanced blades can cause vibration and accelerate wear. Checking the rubber hub regularly is also critical; replace worn or compressed elements if performance degrades.
Store your propeller in a dry, cushioned environment off‑boat during off‑season. Avoid stacking or placing heavy objects on blades. These practices help maintain blade geometry and ensure efficient thrust. A well‑maintained Rubex 3 prop will offer consistent service over several years.
What are common troubleshooting tips for performance issues?
Performance issues such as poor top speed, engine over‑revving, vibration or cavitation often stem from improper pitch selection or hub misalignment. First inspect blades for damage or surface irregularities. Next check hub snugness—if the hub slips on the shaft, thrust is lost. Compare your engine’s actual WOT RPM to its rated range; if RPM is too low, the pitch may be too high. If RPM is too high, using a lower pitch prop such as 12″ may help. In persistent cases, inspect for underwater damage or connect with a certified marine technician.
Some users report vibration after hitting submerged objects. In such cases, replacing the hub and straightening or replacing blades resolves the issue. Always ensure proper torque and nut/cotter pin installation. A loose propeller can damage splines over time, causing costly repairs.
Is the Rubex 3 (9.9 x 13″) worth the investment over OEM props?
Many boaters find that this propeller delivers better acceleration, smoother ride, and improved fuel economy compared to stock OEM aluminum props. The priced range of $100–140 includes the prop and hub kit, making it an affordable upgrade. Compared to stainless steel propellers, it’s lighter and more budget‑friendly, though less resistant to impacts. However, the solid rubber hub helps reduce shock transmission to your lower unit, lowering repair risk. If your engine frequently reaches WOT without hesitation and cruises efficiently, the 13″ pitch can save fuel over time.
For anglers, recreational boaters, or light commercial users, the long‑term value of the Rubex 3 often exceeds its cost, especially when coupled with the 5% discount code option available at select suppliers.
