removing a very long rudder post? (rudder stock is solid 1 1/4" ss).


You don't say if you are wheel or tiller steering.. A two piece rudder would
tend loosen up from constant torsion with a tiller or quadrant above the
shaft coupling.

A coupling would work but in addtion to the splines or key, your coupling
should be split so that several bolt will apply camping force around the
shaft.

Also there should be a bolt going through both the upper and lower so the
weight of the rudder doesn't pull it out of the coupling. This can
accomplished by the clamping bolts passing through a notches in the side of
the shaft.
