Mine is way underpropped so far but runs low 120s at half throttle with the secondaries closed using 18x31 four blades. It was topped at around half throttle with 16 x 34's also but no GPS on board that day.

575's and 35 herrings will get you to the very low 120's but if you make a call to Arizona speed marine???? Oh boy...It helps..
