Aeromarine has always striven to bring you the latest in innovative R/C Marine products. The NEW STS is no exception. The explosion of today's new electric setups have sparked its own set of obstacles to overcome. Hulls need to be virtually hermetically sealed to prevent damage to expensive electronic components. Even the most seasoned builders have trouble with the elusive sealing of the stuffing box tube.  Not anymore! Extensive trial and error testing lead the way to our NEW  Patent Pending STS (Shaft Tube Seals) design. Compact and made of the BEST materials and bearings available. Install this fitting on the end of your stuffing box tube, the precision collar on the shaft, and your tube is sealed from any water entering the hull. Oil fitting is incorporated allowing for easily oiling the shaft between runs without ever taking the shaft out!  High Speed Bearings allows for a frictionless seal.  $26.95
