How to Determine a Left Hand vs. Right Hand Propeller


In this video INDCO illustrates how to determine a left hand versus a right hand propeller. The video features a 3-bladed marine style propeller. We use three methods to determine left hand vs. right hand; blade angle on hub, palm demonstration and flow of material. These methods will work on our steep pitch, square pitch, buffed and mirrored propellers. To view flow of material we use an AS Air Stirrer with a left hand and right hand propeller in water. A left hand propeller will produce downward flow were as a right hand propeller will produce upward flow.

INDCO’s all-purpose mixing propellers are used for mixing, blending, agitating and liquid movement of all kinds. They are available in investment cast 316L stainless steel, roto dull or buffed #4 mirror finish, sand-cast 319 aluminum grade with dull finish and Hastelloy which provides great corrosion resistance than stainless steel. All propellers come with set screws. We offer options such as clipping, cutting pitch changes and electropolishing to all propellers. Contact Customer Service to learn more.
