However, in spite of our best efforts - the prop eventually failed.
Because of our bad experience we decided to replace the folding bronze
prop with a Volvo aluminum prop.

So you feel that a aluminum prop will be less subject to corrosion than bronze?

Yes - and it is also less costly to replace ($200. vs $2,500). On the
other hand, I will lose some speed under sail but since I don't race I
can live with that :-)

The aluminum prop will disappear more quickly, sad to say.

We found that a feathering prop doesn't so much give us better speed as
*some* speed in lower wind strengths. We often pass our motoring dock
mates as we all head home, particularly when we're flying the kite.

Though I agree with the others that say that it's probably another
boat's problems at your dock, it's possible that the problem may be on
your boat. A dock mate mixed up two leads as he reinstalled his
alternator and nearly lost the boat thereby. The charging system
worked, but it accidently caused galvanic corrosion. A "hot" lead to
the bilge pump sitting in the water could do the same if the insulation
were compromised.
