How to Install the New Saturn 12×9 Solas Propeller
Installing the New Saturn 1331-120-09 propeller is a straightforward process. First, ensure you have the correct Solas Rubex hub kit for your Mercury engine. Begin by removing your current propeller, cleaning the shaft, and applying marine-grade grease. Then, slide the hub into the prop, align it with the shaft splines, and tighten the castle nut using a torque wrench to the manufacturer’s specification.
Always use a new cotter pin, and double-check for proper alignment. Installation usually takes less than 20 minutes and does not require any specialized tools. If you’re unsure, seek help from a certified marine technician or follow a step-by-step video tutorial from Solas or Mercury Marine.
Performance Benefits of Using a 12 x 9 Pitch Propeller
The 9-inch pitch of the New Saturn 12×9 prop is tailored for applications where quick acceleration and strong pulling power are more important than high-speed performance. This makes it ideal for boats used in water sports, fishing, and those carrying heavier loads.
With a larger diameter and lower pitch, your engine can reach higher RPMs faster, reducing the time it takes to get onto plane. This not only enhances maneuverability in tight docks or shallow areas but also increases safety and reliability in rough water conditions.
Maintenance Tips
Maintaining your New Saturn – Mercury 12×9 Solas RH Propeller is essential to extend its lifespan and maintain peak performance. After each boating trip, rinse the propeller thoroughly with fresh water to remove salt, sand, and debris. Use a soft brush or cloth to gently scrub away any marine growth or residue.
Regularly inspect the propeller blades for cracks, chips, or bent edges, as these can cause vibration and reduce efficiency. Every few months, remove the prop to check for fishing line wrapped around the shaft and apply fresh marine grease. If your prop suffers any damage, consider professional repair or a replacement to avoid engine strain or lower unit issues.

Detailed FAQ Section
What boats are compatible with the Solas New Saturn 12×9 propeller?
The Solas 1331-120-09 12×9 propeller is compatible with most Mercury outboards from 25HP to 70HP, particularly models from the 2-stroke and 4-stroke ranges. This prop fits small to medium-sized fishing boats, aluminum skiffs, inflatables, and pontoon boats. It is perfect for boaters who need quicker acceleration or plan to tow water toys and require a stronger low-end thrust.
How do I know if a 9-pitch propeller is right for my engine?
Propeller pitch directly affects engine RPM and boat speed. A 9-pitch prop like the Solas New Saturn 12×9 allows your engine to spin faster, which is ideal for boats that are underpowered or carry heavy loads. If your current propeller is too high in pitch and your engine struggles to reach recommended RPMs, dropping to a 9-inch pitch can help restore performance. Always verify with your manufacturer’s WOT (Wide Open Throttle) RPM range for accuracy.
Is stainless steel better than aluminum for propellers?
Yes. Stainless steel propellers offer superior strength, durability, and resistance to corrosion compared to aluminum. They maintain their shape better under high stress and reduce blade flex, leading to more consistent performance and fuel economy. While stainless props like the Solas 12×9 cost more upfront, they often outlast aluminum props by several seasons with proper maintenance.
How do I troubleshoot propeller vibration?
If you’re experiencing vibration, inspect your propeller for physical damage such as dings, chips, or bent blades. Check that the hub is correctly seated and that there’s no fishing line around the shaft. Vibration can also be caused by imbalance or a misaligned prop. If the prop appears visually fine, consult a marine technician to test for balance or consider having it professionally reconditioned.
What’s the average lifespan of the New Saturn stainless steel prop?
With routine care, the Solas New Saturn 12×9 propeller can last over 5–7 years of active use. Regular rinsing, inspection, and greasing of the prop shaft will extend its life. Avoid hitting rocks or sandbars, as stainless steel while strong, is not invincible to physical damage. Proper storage and periodic removal during off-seasons also help increase lifespan.
Conclusion
The New Saturn – Mercury (12 x 9″) Solas RH Propeller, 1331-120-09 delivers exceptional low-end thrust, durability, and fuel efficiency. Designed with precision by Solas for Mercury outboards, this prop is the go-to choice for those who prioritize acceleration, towing capability, and stainless steel reliability. Its high-performance characteristics make it a standout product in the marine propulsion market.
For boaters looking to upgrade, replace, or simply boost their performance on the water, the 12×9 pitch prop offers an unbeatable blend of power and resilience.
