Propeller 101: SOLAS and RUBEX Part Numbers

 

Ever wonder what all those numbers mean on your propeller? Here is a breakdown of the SOLAS propeller part numbers.

Propeller 101: Diameter and Pitch

 

A propeller is defined by its diameter and pitch, which are both measured in inches. Diameter measures the distance across a circle made by the blade tips. Pitch, is the distance a propeller will travel, in inches, through a solid medium, in one rotation.

Propeller 101: Aluminum vs Stainless Steel

 

Solas aluminum propellers use an exclusive squeeze-cast process to make them more durable and non-porous compared to traditional die cast propellers on the market. Solas stainless steel propellers are made with the industry’s highest percentages of chromium, nickel and molybdenum, resulting in a propeller that is more durable, highly rust-resistant and less brittle.

The Rubex Prop Finder is a valuable tool to help in finding a propeller for your boat.

Propeller 101: 3 Blade or 4 Blade

 

3 blade propellers can provide greater top end speed. 4 blade propellers can provide better acceleration and thrust which help get the boat to plane and keep it there at lower speeds. With 4 blade propellers, you may gain bottom and mid-range performance while sacrificing top end.

Propeller 101: SOLAS VS RUBEX

 

Solas propellers are designed to replace a specific engine manufacturer application. It comes with a pressed in-rubber hub already installed which allows you to use the original hardware that came with your engine. Rubex propellers are designed with an interchangeable rubber hub to match a wide variety of outboard and sterndrive engines.
