Detailed FAQ Section
What engines are compatible with the Rubex NS3 13×19 Solas RH Propeller?
The Rubex NS3 13×19 is compatible with a wide range of outboard engines including models from Yamaha (70–115HP), Honda (75–130HP), Mercury (75–115HP), and Suzuki (70–140HP). The compatibility depends on the hub kit you use, so it’s essential to match the correct hub kit to your engine’s make and model. This propeller is specifically designed for 4-stroke and 2-stroke engines where a 13×19 RH stainless steel option is ideal for achieving better planing and midrange power.
How do I know if the 13×19 pitch is right for my boat?
Choosing the correct pitch depends on your engine’s RPM range and your typical load conditions. The 19-pitch propeller is ideal for boats needing higher speed and less low-end torque. If your engine is over-revving, moving up to a 19-pitch propeller like the NS3 can help bring your RPMs into the optimal range. If unsure, consult your boat’s manual or reach out to a marine professional who can analyze your current prop performance and suggest a suitable pitch upgrade.
Can I install the Rubex NS3 myself or do I need a mechanic?
You can absolutely install the Rubex NS3 yourself, especially since it features the Rubex hub system that simplifies the process. Basic hand tools, a prop wrench, and marine grease are all you need. However, if you’re unfamiliar with propeller installation, it’s always a good idea to have a certified marine mechanic do the job—especially to ensure proper torque specifications are met and the hub system is correctly seated.
What makes the Rubex NS3 better than aluminum propellers?
Stainless steel propellers like the Rubex NS3 offer higher strength, better blade rigidity, and longer lifespan than aluminum props. The NS3 maintains shape and performance under higher loads, reduces cavitation, and offers enhanced top-end speed. While aluminum props are lighter and cheaper, stainless steel options provide better grip in water, allowing for faster hole shots, improved fuel economy, and overall durability—especially in abrasive or saltwater conditions.
Is there a warranty on the Rubex NS3 13×19?
Yes, Solas offers a limited warranty on the Rubex NS3 series. The coverage generally includes manufacturer defects and material faults. Warranty duration varies by region and retailer, but most vendors provide a 1-year limited warranty. Make sure to keep your purchase receipt and register the product (if required) on the manufacturer’s website. It’s also worth noting that improper installation or damage caused by collisions or modifications may void the warranty.
