Fixing the propeller shaft to the gearbox with a flexible coupling is an excellent vibration absorber.
Bullflex is the answer when the level of demand increases and more comfort is required for boating. It is designed to dampen vibration and hull noise. The excellent flexibility of the rubber element gives it great damping performance and ensures a quiet and vibration-free transmission between the engine and the axle box.
