I actually talked to someone at Raymarine Tech Support ... after being on hold for 20 minutes ... he said we could use an ST60 wind transducer, but without the ST60 wind display it would read 25% higher wind than reality.

A friend down the dock brought an old ST60 wind transducer he had in the garage - his boat was sideswiped by lightning and he thinks it may still work, but doesn't know for sure. SO, up the mast tomorrow. Keep your fingers crossed!
