Detailed FAQ Section
What makes the Rubex NS3 better than aluminum props?
The Rubex NS3 outperforms aluminum props in durability, performance, and fuel efficiency. Stainless steel blades maintain their shape under load, offering better bite in the water. Aluminum props tend to flex, which leads to less efficient propulsion and higher fuel usage. Additionally, the NS3’s compatibility with interchangeable hubs means less replacement hassle. Over time, the initial investment in stainless steel pays off through reduced repairs and better efficiency.
How do I select the right pitch for my boat?
Pitch refers to how far a propeller moves the boat with one rotation. A 17” pitch like the Rubex NS3 9431-133-17 is a good balance for mid-range acceleration and top speed. To choose correctly, check your engine’s recommended RPM range and compare it with your current performance. If your RPM is too low, consider a lower pitch; if too high, go for a higher pitch. The right pitch maximizes fuel economy and protects your engine from overworking.
Can the Rubex NS3 be used in saltwater?
Yes, the Rubex NS3 is crafted from corrosion-resistant stainless steel, making it ideal for saltwater boating. However, it’s still advisable to rinse your boat and propeller with freshwater after each saltwater outing. This prevents salt buildup and preserves the finish. The Rubex NS3’s tough construction ensures long life even with frequent saltwater exposure.
