Solas Boat Propellers and Rubex Hub Systems
Solas manufactures aluminum and stainless-steel propellers for compatible outboards and sterndrives. The Solas lineup includes fixed-hub propellers as well as Rubex interchangeable-hub designs that pair a propeller with an application-specific Rubex hub kit.
Selecting the correct propeller requires more than matching engine horsepower. Confirm the engine manufacturer, model, year, gearcase size, spline count, propeller series, diameter, pitch, blade count, rotation, and required hub before ordering.
Enter your engine manufacturer, horsepower, model, and year to view compatible propellers and applicable hub-kit information.

Solas Aluminum Propellers
Aluminum propellers provide a practical choice for replacement, general boating, and many original-style applications. Solas offers both fixed-hub aluminum props and Rubex aluminum propellers that use a separately selected interchangeable hub kit.
A three-blade aluminum propeller with a 13.75-inch diameter, 13-inch pitch, and standard rotation. Confirm fixed-hub engine compatibility before ordering.
An Amita 3 aluminum propeller with a 13.5-inch diameter and 15-inch pitch for compatible engine applications.
A three-blade aluminum Amita propeller with a 13.875-inch diameter and 17-inch pitch for its listed fixed-hub applications.
A compact three-blade aluminum pin-drive propeller with an 8.25-inch diameter, 8-inch pitch, and standard right-hand rotation.
A three-blade aluminum pin-drive propeller with a 9-inch diameter and 10-inch pitch for compatible small-engine applications.
Solas Rubex Aluminum Propellers
Rubex propellers separate the propeller body from the engine-specific hub kit. This allows one propeller design to be offered for multiple engine families when paired with the correct Rubex hub and propeller-series application.
A three-blade aluminum Series E propeller with a 14.3-inch diameter, 21-inch pitch, and standard right-hand rotation. Hub kit sold separately.
A four-blade aluminum Series E propeller with a 14.25-inch diameter, 19-inch pitch, and standard right-hand rotation. Hub kit sold separately.
Rubex propeller listings do not automatically include the required engine-specific hub kit. Match the engine application and propeller-series letter to the appropriate Rubex hub kit before ordering. Use our Solas Rubex Hub-Kit and Propeller Fitment Guide for help identifying the correct combination.
Solas Stainless-Steel Propellers
Stainless-steel propellers use thinner, more rigid blades than comparable aluminum designs, but material alone does not determine how a propeller will perform. Diameter, pitch, rake, cup, blade area, engine height, gearcase, hull, and load remain important.
A three-blade stainless-steel fixed-hub propeller with a 13.25-inch diameter, 17-inch pitch, and standard right-hand rotation.
A three-blade stainless-steel Rubex S3 propeller with a 15.125-inch diameter and 25-inch pitch. Verify engine fitment and the required hub kit separately.
Understanding Solas Rubex Hub Kits
A Rubex hub kit connects a compatible Rubex propeller body to a specific engine or sterndrive propeller shaft. The required kit is determined by the engine application and the propeller-series letter—not by horsepower alone.
Different hub kits with similar numbers are not interchangeable by default. Compare the engine manufacturer, model, stroke, year, spline count, gearcase size, and required propeller series with the application chart.
For select Yamaha applications using the D or E Rubex propeller series. Verify the engine model, year, spline count, and gearcase size.
For select Yamaha 250- and 300-horsepower applications and specified Yamaha sterndrives using Series E propellers.
For specified Yamaha VMAX SHO V6 applications. Confirm the complete engine and propeller-series application before ordering.
What May Be Included with a Rubex Hub Kit
A Rubex kit contains the hub and the application-specific installation components shown in its Solas diagram. Depending on the kit, original engine hardware such as a propeller nut, cotter pin, locking hardware, or OEM thrust washer may still be required. The propeller is sold separately.
Transferring a Rubex Hub
An interchangeable hub may be transferred to another compatible Rubex propeller within the applicable series, but it should first be inspected for wear, damage, deformation, and complete hardware. Never assume that a hub fits a different propeller series or engine application.
How to Choose a Solas Propeller
Start with the Engine Application
Record the engine manufacturer, model, horsepower, model year, gearcase size, spline count, and current propeller information. Engines with the same horsepower can use different gearcases and hub kits.
Confirm Diameter and Pitch
Diameter is the width of the circle made by the blade tips. Pitch is the theoretical forward distance a propeller would travel in one revolution without slip. Changing pitch can affect engine rpm and boat operation, so remain within the engine manufacturer’s recommended wide-open-throttle range.
Compare Three- and Four-Blade Designs
A four-blade propeller may provide different acceleration, lift, grip, or handling characteristics, while a three-blade design may reduce blade area and drag. Results vary by propeller geometry and boat setup; blade count alone does not guarantee a specific outcome.
Choose Aluminum or Stainless Steel
Aluminum propellers are commonly selected for replacement and general boating. Stainless-steel propellers provide greater blade rigidity and allow different blade geometries, but they are not automatically the best option for every boat or engine.
Check Rotation
Most single-engine applications use standard right-hand rotation, but some twin-engine and specialized installations require a left-hand propeller. Verify rotation from the existing propeller, engine documentation, or application data before ordering.
Identify the Hub Type
A fixed-hub Solas propeller must match the engine application built into that propeller. A Rubex propeller requires a compatible interchangeable hub kit selected for both the engine and the propeller series.

Solas Propeller FAQs
How do I find the correct Solas propeller for my engine?
Use the Propeller Finder and enter the engine manufacturer, horsepower, model, and year. Confirm the resulting propeller series, diameter, pitch, rotation, gearcase size, and required hub against the individual product listing.
What is the difference between Solas fixed-hub and Rubex propellers?
A fixed-hub propeller has an application-specific hub built into the propeller. A Rubex propeller uses a separately selected interchangeable hub kit that connects the compatible propeller series to the engine propeller shaft.
Does a Solas Rubex propeller include the hub kit?
Not unless the individual listing explicitly says it does. The featured Rubex propellers require a separately purchased engine-specific hub kit.
Can I choose a Rubex hub kit using horsepower alone?
No. Match the engine manufacturer, model, stroke, year, spline count, gearcase size, and required propeller series. Engines with the same horsepower may require different hubs.
Can the same Rubex hub be used with another propeller?
It may be transferred to another compatible Rubex propeller within the applicable series when the hub and hardware remain serviceable. Inspect all components and confirm compatibility before reuse.
Is a four-blade propeller always better than a three-blade propeller?
No. Three- and four-blade propellers create different operating characteristics, but the result depends on the complete blade design, engine, hull, load, and setup. Select the propeller that best matches the boat’s requirements.
Should I choose an aluminum or stainless-steel Solas propeller?
Aluminum is a practical choice for many replacement and general-use applications. Stainless steel offers greater blade rigidity and different design possibilities. Consider the engine, boat, operating environment, current performance, and budget.
Can I replace an OEM propeller with a similarly named Solas series?
A comparison between propeller families does not prove direct fitment or identical performance. Verify the exact Solas part number, engine application, diameter, pitch, rotation, blade design, and hub requirements before replacing an OEM propeller.
How do I know whether my propeller pitch is correct?
Run the boat under its normal load and compare wide-open-throttle rpm with the engine manufacturer’s recommended range. Engine condition, loading, hull condition, mounting height, and other setup factors should also be checked before changing pitch.
