New gear ratio and propeller
· New gear ratio 2:1 for IPS3 will be used for rating 3 and 4
· Rating 5 and rating 4 above 38 knots will use existing ratio 1.88:1
· Rated RPM for rating 3 is set to 2250 (2300 for rating 4 and 5)
· New propeller QS5 for both rating 3 and 4 together with gear ratio 2:1
· Optimized for lower speed
· Increased diameter and blade area
