AQUADRIVE anti-vibration system not only reduces the need for precise alignment between the engine and the propeller shaft. It also eliminates the need for stiff, hard mounts. This leads to better space utilization while dramatically reducing vibration and noise. Some of the most distinguished boat builders in the world use AQUADRIVE as standard equipment, Grand Banks, Fleming Yachts and Hinckley just to mention a few. AQUADRIVE covers inboard installations up to 1500 HP.
