[C320-list] Prop nut

[Rick Sulewski]

Ted,
I have a single prop nut on my boat (hull #277).  To remove the prop I had
to strike the end of a wrench with a hammer several times to loosen the
jammed nut against the prop. Be careful to use a closed end wrench or a deep
socket wrench that provides a stable target to strike the end of the wrench
and strike the furthest end of the wrench while the transmission is in
neutral. For me, there was no need to contain or attempt to keep the prop
from turning.  For me, I just had to reset the prop and wrench to provide
several high force strikes in order to break the nut free. I reversed the
process to jam the nut against the prop to ensure the prop was indeed
reseated on the tapered shaft.

I second the earlier post indicating the need to keep the loosened nut on
the end of the shaft when pulling the prop so as to avoid having the prop
fly off the shaft. When pulling the prop I had to tightened the tool several
times by striking the wrenches to place pressure on the puller and finally
just walk away.... and the prop popped off while I waited for the
tension/pressure to do its work. The prop nut kept the prop from flying off
the shaft toward the rudder.

Allan, 

Our boat only had a single large castle nut installed with cotter pin.
Catalina direct also confirms this was standard...

There should be two - one is half-height, the other full-height.  And while
this sounds counter-intuitive, the half-height nut goes on first against the
hub.  The half-height nut initially takes the load but when the full-height
nut is installed, the load is transferred to that one.  See:
http://www.passagemaker.com/channels/propeller-nut-myth-busting/

Most very boat I have seen, including my own, had the full-height nut
installed first.
