[C320-list] Bolt size specification needed, please

[tharrison at innovations-plus.com]

Interesting point. I did not know that about the engine mounts. 

I have never heard of anyone broaching or let invert the Catalina 320. I am not sure if any one you even confess to such an event.

 As a new sailor and owner of a 320 I would buy a pint to hear such a story. I am of the theory it is better to hear of one such experience, learn and how to best prepare oneself.
(Without becoming a fair weather sailor and the boat rarely ever leave the dock)

The main reason I wanted to re-use the existing holes though was to avoid the need to lift the engine to any great degree. I figured that if I can do one cormer at a time I can slip the old mounts out and the new ones in.

The previous owner didnt tighten his fuel line properly and a small weep of diesel fuel dripped down onto the mount and has disbonded the rubbed from the metal (as well as saturating some woodwork, the aft cabin carpet and so on!). The R&D mounts are about half the cost of yanmar and have the benefit of being exact replacemenst in terms of the hole drilling pattern, as well as being fail safe should the boat ever invert (!!) the engine cannot detach from the  mounts. Also they are protected should a fuel leak re-ocur. However instead of being about 1/4” thick where it attached to the bearer, its about 3/8” hence the need for a slightly longer bolt.
