Yamaha 9.9hp Propeller

I have a single g series motor 212 cc high thrust.This was supplied with the 9.25 inch pitch prop which I have recently replaced with the 7 inch pitch prop.These props appear to be the same size as used on the earlier model motors 300+cc which develop 9.9 hp at 500 rpm less than the 212cc motor.
The results sofar are max rpm went from 4500 to 5300,max speed from 6.5 to 6.8 knots and feul consumption about the same 1.3 litres per hour at 5 to 5.5 knots in calm water.
I would be interested to hear of others findings.
