Hi Bruno.
If this has been mentioned then I missed it.
Please tell your friend (Fred) that a very
important step in a successful prop shaft install
is to true the flange face with it mounted to the
shaft. Even with a brand new custom shaft & brand
new coupling half, it is good to true the face
before install. The shaft is easily bent a wee bit in handling.
The truing process is really basic in the
machining world, even an apprentice might be tasked to it.
Cheers, Russ

Hello listers,
Thanks for the support, i received some good
tips and it helps to limit potential errors.
here is the update on the situation. the cutlass
and drive saver plate are already on order. the
most complicated part is to find or calculate
the right lenght of the prop shaft. the actual
broken one was new before departure last july,
as is the PSS and the cutlass that will be
replaces as a precaution. my friend wants to
have all the parts, and then do the repair with
the boat on a rustic travel lift nearby.
the boat is a CS 36 Merlin 1988 with a Volvo
engine, the transmission has a 4 inches flange.
the shaft is 1 inch diameter and "about" 66 to
70 inches long. Mine is 44 on my 33mkII So its
pretty long...The prop is a Martec So everything
points to a standard SAE Taper That is
usually found on our boats, the key is 1/4 and
the coupling is actually a split coupling that
could fit on a "on the spot home cut to the
right lenght, not face fitted" shaft. but if he
could have the shaft lenght from a good source,
a new fitted coupling would be on order.
I have been in contact with DeepBlue yacht
supply in Fort Lauderdale and it seems easy to
order from their website. there is 3-4 days
production time before shipping. The good
reviews from this list are reassuring. Thanks.
SO, i am still looking for the original shaft
lenght, are the CS plans available at the
Maritime museum too? Any others sources for that
info that i could get my hands on before
tomorrow? I doubt Holland Marine has that info but will try tomorrow.
ALSO, we are still looking for someone that
could pickup the shaft at DeepBlue yacht supply
and bring it few blocks away at Reggie Express
services that Fly from there to Georgetown,
Exumas. we want to save the additional shipping
delay from UPS. Its just few kilometers away...
Thanks for helping a fellow sailor and his
family. the CS is still a very nice boat!

of a CS newsgroup similar to our C&C group it could be of a big help.
