Outhaul Internal Boom Sheaves and Rigging

[RaymondP]

With the first season of sailing on my 86 C34 Mk I now ended, I had experienced a hard time adjusting the outhaul.  Taking the boom internals apart looks like the sheaves are crumbling, a real mess!  Can anyone tell me the size of the internal sheaves inside the boom and a source for replacement.  Very open to advice and suggestions on sheave materials as well as modifying the configuration. Currently it is set up to adjust at the mast end but would prefer to operate from the back of the boat as I am often short-handed.

I have the diagram of the current internal arrangements and also notice Catalina Direct sells a replacement "kit" that provides a greater mechanical advantage (10-1?), but does not include all the internal sheaves or a line that is long enough to run to the rear of the boat for easy adjustment from the cockpit. Was thinking I could purchase the individual components and design/modify as preferred, but not sure if it would be worth it.

Would welcome input on anyone's experience in this area as well as potential resources.  Thank you.

Garhauer Marine, https://www.garhauermarine.com/, can probably tell you you the size, and definitely provide a replacement at a reasonable price.  👍👍
