Common Troubleshooting Tips for LH Marine Propellers

If you experience vibration, cavitation, or loss of thrust, your propeller may be damaged, misaligned, or incompatible. Inspect for bent blades or dings. If the prop is slipping under acceleration, the rubber hub may need replacement. Check for marine growth or corrosion on the prop shaft.

Other issues like excessive RPMs at low speed may point to incorrect pitch. The 17-inch pitch of this prop offers a balance, but if you’re over-revving, consider upgrading to a 19″. For boats struggling with low-end power, a 15″ pitch version may be ideal.

How to Choose the Best Stainless Steel LH Propeller

When choosing a propeller like the Rubex NS3 LH model, prioritize blade design, pitch, diameter, and hub compatibility. The 13.25-inch diameter and 17-inch pitch strike a good balance between acceleration and speed for mid-HP outboards. Stainless steel options like this are more durable and perform better in saltwater environments.

Ensure that the rotation direction (LH vs RH) matches your engine, especially in twin-engine setups. Always refer to your engine manufacturer’s prop selection guide and match shaft diameter and spline count.

Detailed FAQ Section

What makes the Rubex NS3 LH propeller better than aluminum props?

Stainless steel props like the Rubex NS3 (13.25 x 17″) LH model offer superior strength, durability, and performance over aluminum. They resist corrosion, maintain blade shape under load, and provide better fuel economy and speed. The Rubex NS3 specifically adds rubber hub cushioning for quiet operation and is ideal for saltwater use, whereas aluminum is softer and may deform over time. If you’re serious about your boat’s handling and long-term investment, upgrading to stainless is highly recommended.

How do I know if my outboard needs a LH (left-hand) propeller?

Left-hand propellers are typically used in twin-engine boats where one engine spins in the opposite direction to balance torque. If you’re replacing an existing LH prop, match the rotation accordingly. Look at your current prop’s markings or consult your engine manual. Some single-engine boats also use LH props depending on engine configuration. Always confirm rotation before purchasing.

Can the Rubex NS3 LH propeller be used in saltwater?

Yes. The Rubex NS3 LH propeller is constructed from marine-grade stainless steel, making it ideal for saltwater environments. Its corrosion-resistant finish and robust hub system reduce wear caused by saltwater exposure. After saltwater use, it’s crucial to rinse the propeller and shaft with fresh water and inspect for residue or corrosion as part of routine maintenance.

Is the Rubex hub interchangeable with other Solas propellers?

Absolutely. One of the standout features of the Rubex system is its hub interchangeability. The same Rubex rubber hub can be used across many Solas propellers, making prop changes quick and cost-effective. This system reduces the need to buy a new hub each time you change pitch or upgrade your propeller material, making it an ideal solution for boaters who like to tune performance.

What size engine is compatible with the Rubex NS3 (13.25 x 17″) LH Propeller?

This propeller is best suited for outboards in the 90–140 HP range. Brands like Yamaha, Honda, Suzuki, and Mercury have compatible models when used with the correct Rubex hub kit. Always check the spline count and shaft diameter to ensure proper fit. This 17″ pitch is especially well-suited for boats requiring a balance of speed and torque.

Conclusion

The Rubex NS3 (13.25 x 17″) Solas LH Propeller, 9432-133-17 is a premium upgrade for boaters looking to boost efficiency, control, and reliability. With its stainless steel construction, balanced performance, and interchangeable hub system, it’s an excellent choice for anyone serious about marine propulsion.
