I replaced my rudder in '98. Here are my weights:
New rudder/fittings = 85 lbs
Fittings alone = 8 lbs
wet rudder with fittings = 88 lbs
cost delivered to FL with buff colored Gelcoat was $1100 ( white was $150 less )
My rudder was split at the trailing edge after a run in with a winter stake at a nearby mooring.
I put the rudder on without hauling the boat which was a royal pain.
Good Luck
