Stainless vs. Aluminum Props

[Hammerhead]

I run SS props...and scrape bottom on a regular basis. Mostly sand around here but, in Miami I run from Key Biscayne south across the safety valve flats to the upperkeys. It' gets skinny as 8" at high tide in some places. When I feel it hit bottom I usually heel it over on the chine and ride it out or turn around. This is in my 16' Bonita w/90Yam. The V-20 stays in the channel.
