Rubber mount of C-drive with keel


 

If the aft part of the C-Drive can be moved to either side by 10mm, or more, the C-Drive Foot Rubber Bushing absolutely needs to be replaced. The recommendation is a side-to-side movement of 5mm or less. The rubber bushing replacement part is a piece of heavy-duty 1” or 25mm hose. 

I am betting there are more than a few C-Drives that need this. Step-by-step procedure in my book.

Bill,
You're a star. Just what I needed to know. And compared with the state of mine it explains the vibration I've been experiencing on the C Drive Vetus mounts despite having carefully realigned the engine.

Thanks again.

Bill,
Just replacing mine (Santorin), 1" boss fits fine. Question is what length. The old one is shorter than the ! length of the sleeve, but this may be wear a d compression.
I am assuming it should be cut to the same length as the sleeve. Right of wrong?  Any advice gratefully receivec, otherwise it will be 'suck it and see'.

Thanks

My propeller was vibrating rather strongly when motor sailing in non-flat waters.  Such vibration was only felt during certain parts of the up and down motion with the waves.  In Martinique, the boat was taken out of the water to tighten the rubber bushing the links the C-drive with the keel.  It is a rubber sleeve with ~ 7/8" ID and ~40 mm OD and ~35 mm long.
  They told me that all they needed to do was to tighten the bolt that would squeeze the rubber tube expanding it and eliminating the play.  Actually, the rubber sleeve  was already squeezed at max and had deteriorated to the point that it was allowing motion even though the bolt was tightened at max.  Unfortunately, Amel did not have with them a replacement and they made one by wrapping silicone rubber tape around a plastic tube.  This reduced the vibration but it was still noticeable and I was concerned the rubber was going to disintegrate with time.  
So I am now replacing it with something that should last the rest of the boats like.

MY QUESTION IS:  does anybody have the exact dimensions of the rubber tube (particularly the Length) and the material it was made of?
