Shaft Vibration Eliminated With Vesconite Hilube
After replacing the all-rubber cutlass bearing of his new Jeanneau Sun Fast 35 Tide The Knot two times in seven years, Robert Metzen sought an alternative. A fellow sailor told him about his positive experience with Hilube as a rudder bearing. Shortly after contacting Leandro Panzini from Vesconite distributor VesArg, Metzen had a state-of-the-art polymer bearing installed.At 2,300 rpm, a sailboat engine will spin its propeller shaft a million times in less than eight hours. Cutlass bearing materials such as rubber and bronze wear prematurely.
Optimized Outboard and Sterndrive Power
A portion of the energy created by a propeller is lost from upward flow. The Whale Tail XL from Davis Instruments is a stabilizer and ski boat fin that takes this wash and powerfully directs it aft.Whale Tail XL's unique hydrodynamic design generates lift for improved acceleration to plane and increased top speed.
