• Allows the engines to be tilted independently
• Stainless steel components
• Electropolished stainless steel ball joints

ATTENTION: As the tiller arm position varies from engine to engine and the distance between two engines is not predictable, unexpected interferences may occur while tilting.
We recommend that, after the tie bar installation, you carefully check for binding when both engines are tilted, or when one is tilted but the other is not (say, in the case of one engine breaking down.
