hi, have a 14ft ski boat, with a 130 johnson ocean pro, with a 1.86:1 gear ratio it does 80km/h with a 14.125 x 17 prop at 4900rpm, i realise this is not revving enough so am curious as to speeds others with a similar setup are getting, please share what you know or suggest what prop type and size would get me going as fast as possible,

thanks
