AST-P-789 Prop Polisher & Barnacle Buster

"Proven Money Maker"

The AST-P-789 was specifically designed for polishing ship propellers using two 9" (228.6 mm) O.D., 3M Prop Polishing Marine Discs.  Two high powered hydraulic motors turn in counter rotation which eliminates the torque effect.   Thus reducing diver fatigue. The unique design allows cleaning up to the blade route.  The low profile design contours and cleans in confined areas.   Mounted on a flexible base allowing the AST-P-789 to conform to any propeller surface.  Approved by all classification societies for use on all types of vessel propellers.
