Detailed FAQ Section

Which outboard engines are compatible with the Rubex C4 (11.5 x 13″) propeller?

This propeller is compatible with a wide range of 40HP–140HP outboard engines. It fits major brands like Yamaha, Mercury, Evinrude, Johnson, Suzuki, and Honda when paired with the appropriate Rubex hub kit. The Rubex interchangeable system simplifies compatibility across different engine makes, ensuring a perfect and secure fit.

How does a 4-blade propeller differ from a 3-blade in marine applications?

A 4-blade propeller like the Rubex C4 offers enhanced acceleration, smoother cruising, and better performance under load. Compared to 3-blade props, 4-blade models generate more grip in the water, making them ideal for towing or rough waters. However, they may slightly reduce top-end speed—something most users are willing to trade for improved control and torque.

What are the best maintenance tips for this propeller?

Regular maintenance includes rinsing after saltwater use, inspecting blades for any deformation or cracks, and applying marine grease to the propeller shaft. Avoid striking submerged objects, and ensure the prop nut remains tightly fastened. Store your boat and propeller in a dry, covered location when not in use to prolong lifespan.

How do I choose between different pitch sizes for my boat?

Pitch determines how far your boat moves forward in one prop rotation. A 13” pitch like this Rubex C4 offers a balanced mix of power and speed. If your boat struggles with acceleration or hauling loads, opt for a lower pitch. If you desire more top-end speed and have a light boat, a higher pitch may be more suitable. Consulting your engine’s manual and speaking with experts at AllBoatSupplies can help make the right choice.

Is stainless steel worth the investment over aluminum propellers?

Absolutely. Stainless steel propellers, including the Rubex C4, are significantly more durable and efficient than aluminum alternatives. While the initial cost is higher, stainless steel props maintain shape under stress, last longer, and offer better performance—especially in saltwater or heavy-use environments. Over time, the reduced need for replacements makes them a cost-effective option.

Conclusion

The Rubex C4 (11.5 x 13″) Solas RH Propeller, 9333-115-13 is the perfect blend of strength, performance, and reliability.
