- Improved blade rigidity, maintaining pitch under load
- Greater efficiency and fuel savings
- Exceptional resistance to saltwater corrosion
- Reduced cavitation and prop walk
Maintenance Tips
Stainless steel propellers are built to last, but that doesn’t mean they’re maintenance-free. Following a simple routine ensures your PROP SS BRAVO II 15 continues to deliver maximum performance season after season.
- Rinse After Use: Always rinse with fresh water after saltwater outings to prevent surface corrosion.
- Inspect for Damage: Look for nicks, cracks, or bent blades monthly.
- Check Prop Shaft: Remove and inspect the propeller shaft quarterly to ensure there’s no fishing line or debris.
- Lubricate: Apply marine grease to the shaft during seasonal maintenance.
- Replace Hub if Worn: The hub should be replaced if you feel excessive slippage or vibration.
Bravo II Propeller vs Bravo III: Key Differences
Many boaters compare Bravo II and Bravo III propellers when shopping for performance upgrades. The PROP SS BRAVO II 15 is optimized for single propeller systems with large-diameter blades, providing excellent thrust for heavier boats and lower planning speeds. In contrast, Bravo III uses counter-rotating dual propellers for faster acceleration but often at a higher cost and maintenance complexity.
Bravo II props like the PROP SS BRAVO II 15 P-1641-193-15 are easier to maintain and ideal for fishing boats, cruisers, and utility boats where steady pulling power is more important than quick hole shots. The single large stainless prop blade provides excellent control and fuel savings in choppy or tidal waters.
Expert Advice and Pro Recommendations
Marine propulsion experts recommend the PROP SS BRAVO II 15 P-1641-193-15 for boaters looking to improve mid-range thrust and reduce long-term maintenance costs. This propeller is a solid choice for commercial operators and seasoned anglers who need dependable power and lower operating costs over the long haul.

Detailed FAQ Section
What boats are best suited for the PROP SS BRAVO II 15 P-1641-193-15?
The PROP SS BRAVO II 15 P-1641-193-15 is best suited for boats using MerCruiser Bravo II sterndrives. These include larger cruisers, commercial fishing boats, heavy utility vessels, and some high-torque pontoon boats. If your boat operates in strong currents or requires towing power, this propeller will provide better thrust and blade strength compared to standard props. Always check shaft specs and hub compatibility before purchasing.
How do I troubleshoot cavitation issues with this propeller?
Cavitation is often caused by air bubbles forming around the blades, leading to vibration and reduced thrust. If you’re experiencing this with the PROP SS BRAVO II 15, inspect the blade edges for pitting or damage. Make sure the propeller is installed at the correct height and that the engine is trimmed properly. Cleaning marine growth from the hull and checking the hub condition can also resolve most cavitation-related issues.
How long does a stainless steel propeller like this last?
With proper care, the PROP SS BRAVO II 15 P-1641-193-15 can last over a decade. Unlike aluminum props, stainless steel blades resist bending and flexing under load. They also withstand saltwater corrosion far better. Regular maintenance—like greasing the shaft and rinsing after use—will significantly extend its lifespan. For commercial use, a 5-7 year life cycle is typical with seasonal inspections and prompt repairs.
Can I switch from an aluminum to this stainless steel propeller?
Yes, switching from aluminum to stainless steel is a common upgrade that many boaters make for improved performance. When switching to the PROP SS BRAVO II 15, ensure your current prop size (pitch and diameter) matches, and verify that the hub system is compatible with your lower unit. You may notice improved fuel efficiency, stronger acceleration, and better handling during tight maneuvers after making the switch.
What’s the difference between 3-blade and 4-blade props in this category?
The PROP SS BRAVO II 15 P-1641-193-15 is typically a 3-blade design, providing excellent top-end speed and efficient fuel use. A 4-blade prop offers slightly better grip in rough water, more lift, and faster planing, but often at a minor sacrifice in top speed. For most Bravo II applications, the 3-blade stainless design offers a balanced combination of power and economy, ideal for everyday marine use.
Conclusion
If you’re ready to take your boat’s performance to the next level, the PROP SS BRAVO II 15 P-1641-193-15 for marine is the upgrade you need. Built for power, speed, and efficiency, this stainless steel propeller offers everything a serious boater demands—longevity, strength, and precision. Whether you’re heading offshore or navigating coastal shallows, trust this prop to deliver consistent performance with minimal maintenance.
From smoother acceleration to improved fuel economy and corrosion resistance, this Bravo II-compatible propeller stands as one of the best stainless steel options in its class. Don’t settle for less when the best is just a click away.
