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.

Well, in that case the Volvo sail drive housing - mado of aluminum - should
have disappeared long ago - however it is like new after some 5 years....

Also, considering that savings by not having a diver replace the 3 small
zincs on the Volvo bronze folding prop (appproximately 4 times a year x
$100.) it is still less costly to replace the aluminum prop say once a year
if needed.
