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
