propellers sizes

[africantiger]

re the propeller on twin screw the same size as single screw riva boats?
i need new junior propeller but in opposite rotation as just fitted a engine with the wrong rotation and was wondering if i could use one propellor from an ariston or aquarama?

1. depends on it you have an Italian Riva shaft. Riva shaft is not the same as a USA tapered shaft.
2. If you have USA taper shaft there are lots of props over here.
3. If you have Riva shaft you will need a Racine Prop like original which you could buy from Morosini

Where are you located?
