Doesn't look like they make one in a Shamrock size- "Sharrow MX inboard Available for inboard applications from 25 inches to 60 inches in diameter" Outboard models start at 5K ?? I guess one for my 17 is out of the question

Lets just say I can see a 30% decrease in fuel consumption....how long would it take to ever pay off $10k ( twin engines ) in new props?

( If I buy $33,400 in fuel, and save 30% = $10,000 ....Props paid for themselves! )

But worse than that, you know at some point your gonna need it repaired, I'd bet my local prop shop wouldn't touch that thing!
