Cost was not mentioned , and a few hundred more in the boating world is pocket change . Pontoon slipped next to me does 55 mph. Not bad for a " barge " is it ? Yep , he runs a SS prop , told me he gained a few mph over aluminum as the mfg can do more tweaking with a SS prop over aluminum . And the SS have hubs in them , so when you hit something the hub gets blown out ,before transferring that hit to the prop shaft . The SS will take small hits with nary a mark vs Aluminum that gets bent with the lightest of hits . To each there own , you think aluminum is better then stick with them . I will stick with my SS and Nibral props , thank you .
