Solas Rubex L3 Aluminum 3-Blade Propeller – 13.75" x 13", RH Rotation (9411-138-13)

Solas Rubex L3 Aluminum 3-Blade Propeller – 13.75" x 13", RH Rotation

The Solas Rubex L3 is a squeeze-cast aluminum 3-blade propeller built around the Rubex interchangeable hub system. The 13.75" x 13" pitch is a lower-mid option in the L3 lineup, offering strong acceleration and excellent bow lift — a good fit for heavier boats, higher-load applications, or outboards that need help reaching their WOT RPM range with a higher-pitch prop.

The Rubex system separates the propeller housing from the hub, so if the blades are damaged, you only replace the housing — not the entire propeller assembly. The hub is reusable in most cases, keeping long-term ownership costs low.

Key Features

• Squeeze-cast aluminum construction — denser, stiffer blade than conventional die-cast aluminum for better efficiency and durability
• 13.75" diameter x 13" pitch — lower-mid pitch for strong acceleration and bow lift
• 3-blade configuration — strong acceleration with good top-end capability
• Right-hand (standard) rotation
• Interchangeable hub system — replace only the housing if blades are damaged; hub is reusable
• Rubex E-Series hub compatible — requires an RBX hub kit, sold separately

Required Hub Kit

This propeller housing requires a Rubex E-Series RBX hub kit, sold separately. See the Solas Rubex RBX-102B Hub Kit – E-Series or RBX-104B Hub Kit – E-Series for compatible options. Verify your engine application using the Solas Rubex application chart at rubexprops.com.

Parts Desk Insights

The 13.75" x 13" is a lower-mid pitch in the Rubex L3 line and the right recommendation when a customer’s engine is over-revving at WOT with a 15" pitch, or when they need more acceleration and bow lift for a heavier hull or higher-load application. It’s also a good option for customers who are stepping down from a 15" that’s pushing the engine below its WOT RPM range. If the engine is still over-revving with this prop, step down further to the 14" x 11" or 14" x 9". If it’s under-revving, step up to the 13.5" x 15". Always confirm the correct RBX hub kit for the engine before completing the sale — the RBX-102B and RBX-104B are the most common E-Series options. If a customer comes in after a prop strike, check whether the hub is intact — if so, they only need a replacement housing.
