PROP SST EJ 90-300HP 17L

Introduction
The PROP SS M/M 90-V6/IO 21 P-1541-148-21 is a precision-engineered stainless steel propeller tailored for high-output marine engines and sterndrive systems. Designed to maximize thrust, reduce vibration, and ensure long-lasting performance, this propeller is a top-tier choice for boaters seeking efficiency and durability. Whether you’re fishing offshore or cruising on open water, the PROP SS 90-V6/IO marine series offers exceptional reliability under all marine conditions.
Made from corrosion-resistant stainless steel, this model is known for its 21-pitch specification, perfect for delivering a balance between acceleration and top speed. In a world where propeller quality can make or break marine adventures, this model stands tall as a durable performer.
Overview / What Is PROP SS M/M 90-V6/IO 21 P-1541-148-21?
The PROP SS M/M 90-V6/IO 21 P-1541-148-21 is a premium stainless steel propeller crafted for mid to high horsepower V6 outboard engines and I/O (inboard/outboard) systems. Featuring a 21” pitch, this propeller offers optimal balance between top-end speed and responsive thrust, suitable for larger vessels or those requiring heavy load performance.
Built with Solas’ signature casting precision and hydrodynamic engineering, this model is ideal for boaters looking to upgrade from stock aluminum props. It is compatible with various brands including Mercury, Yamaha, and Volvo Penta when paired with the correct hub kit.
Why Pitch and Blade Design Matter
The 21 pitch specification on the PROP SS 90-V6/IO marine propeller determines how far the propeller will move a boat forward with one revolution. A higher pitch offers greater speed but requires more engine power, making it ideal for powerful engines (90HP to V6 ranges).
This model typically comes with a 3-blade configuration for enhanced speed and acceleration balance. It improves hole shot performance (how quickly your boat gets on plane), and maintains RPMs within the optimal range, ultimately increasing engine longevity.
Material Advantage: Why Stainless Steel Beats Aluminum
Stainless steel propellers like the PROP SS M/M 90-V6/IO 21 P-1541-148-21 significantly outperform their aluminum counterparts in both durability and efficiency. Stainless steel is harder and more resistant to damage from debris and underwater obstacles.
In addition, stainless steel blades are thinner and more hydrodynamically efficient, allowing better water flow and less drag. This means more thrust, better fuel economy, and longer propeller life—key benefits for every marine enthusiast.
Compatibility and Hub Systems
The PROP SS 90-V6/IO marine propeller is compatible with multiple marine engines when used with a matching Rubex or Solas hub kit. It’s especially popular for:
- Mercury V6/V8 Outboards
- MerCruiser Sterndrives
- Volvo Penta SX & DPS series
Ensure your propeller is paired with the correct thrust washer, spacer, and drive adapter. Using a rubber-cushioned hub can also reduce vibration and gear shock, enhancing the longevity of your lower unit.
Maintenance Tips
To maximize the lifespan of your PROP SS M/M 90-V6/IO 21 P-1541-148-21, routine maintenance is essential:
- Inspect regularly: Check for dings, cracks, and signs of cavitation.
- Grease the shaft: Apply marine-grade grease to the propeller shaft every few months to prevent corrosion and seizing.
- Remove and clean: Remove the propeller periodically to clean out fishing line or debris wrapped around the shaft.
Additionally, store your boat out of the water or use propeller covers to protect the prop from UV damage and marine growth during long-term storage.
Performance Insights: How This Propeller Improves Efficiency
The PROP SS M/M 90-V6/IO 21 P-1541-148-21 is engineered for minimal slip and maximum bite in the water. Its optimized rake angle improves handling and enhances bow lift, ideal for planing hulls and offshore applications.
This prop also reduces ventilation and increases fuel efficiency, giving you more mileage per gallon. Whether you’re towing, cruising, or fishing, its torque-to-speed conversion ensures smoother rides even in choppy waters.
Installation Guide: How to Install PROP SS 90-V6/IO Marine Propeller
Installing your PROP SS 90-V6/IO marine propeller is straightforward:
- Remove the cotter pin and propeller nut from the existing prop.
- Slide the propeller off the shaft carefully.
- Grease the shaft and place the appropriate hub kit (if required).
- Mount your new stainless steel propeller, ensuring all washers are aligned.
- Tighten the nut to torque spec and secure with a new cotter pin.
For best results, use a torque wrench to avoid over-tightening. Always test the prop on idle before heading into open water.
Expert Advice and Pro Recommendations
Marine professionals recommend the PROP SS M/M 90-V6/IO 21 P-1541-148-21 for those upgrading from standard aluminum props. It’s ideal for moderate to heavy boats, delivering performance without sacrificing reliability. The stainless steel build means fewer replacements and better performance season after season.

Detailed FAQ Section
What boats are best suited for PROP SS M/M 90-V6/IO 21 P-1541-148-21?
This propeller is perfect for medium to large boats powered by V6 outboards or I/O engines. These include performance fishing boats, bowriders, cruisers, and sport boats. The 21” pitch is ideal for users seeking a balance between acceleration and top speed, especially when carrying heavy loads or towing.
How often should I service my stainless steel propeller?
It’s recommended to inspect your stainless steel propeller every 50-100 hours of engine time. Look for nicks or warping and grease the shaft during each inspection. Annual removal and deep-cleaning during winterization is also suggested to prevent marine buildup and shaft corrosion.
Can I install this prop myself, or do I need a technician?
Yes, you can install the PROP SS 90-V6/IO marine propeller yourself using basic tools like a wrench and marine grease. However, if you’re unsure about the hub compatibility or torque specs, it’s always best to consult a marine technician for safe installation.
What’s the expected lifespan of this stainless steel propeller?
When maintained properly, stainless steel propellers can last over 5–8 years. Their resistance to damage, cavitation, and corrosion makes them a smart investment for regular boaters, compared to aluminum props which typically degrade faster in saltwater conditions.
Is the 21-pitch too high for my engine?
It depends on your engine’s horsepower and your boat’s size. If you’re unsure, review your engine’s WOT (wide-open throttle) RPM range. If installing this 21-pitch propeller causes your engine RPM to drop below the manufacturer’s recommended range, you may need a lower pitch. Conversely, if RPMs are too high, this prop could stabilize your performance.
Conclusion
The PROP SS M/M 90-V6/IO 21 P-1541-148-21 is a high-performance, durable, and efficient marine propeller that delivers consistent results for serious boaters. From improved fuel efficiency to reliable handling under load, this stainless steel prop is an excellent investment in your boat’s propulsion system.
