Came across this:



Interesting idea but I am not sure if will will work on RC boats. Imagine balancing one of these...

Pretty crazy idea ... Mr. Sharrow will probably become a millionaire several times over...

What ever a pair of those on a twin engine boat cost, they will more than likely pay for themselves in fuel savings alone.

My son was just showing me these a couple nights ago. These are a game changer. I am sure they could be molded and made for our little boats. the patent rights would be expensive though . Might not be enough sales to make them worth going and getting it all done for r/c boats and I am unsure how they would react with high rpm and not being fully subsurface.
