mercury spitfire

[badfish888]

guess its new from mercury, and they have a decent video on the MERC site, they say with the same pitch but a smaller diameter, u can keep your engine rpm, and still get the benefits of a 4 blade, question is, do i get the same pitch i have now on my 3 blade? or less pitch cause my engine has more blades it has to turn now?
