Grimracer 42X55 ?

Hi all not the least bit familiar with Grimracer props ! What diameter and pitch is the 42X55 ? Which prop in the Octura and ABC brands would be comparable to the 42X55 ? Im back to experimenting with my Dunlap W.O.F 30 outboard tunnel hull with a AQ 2030 KV on a O.S lowerunit and 4S power. Regards Andris Golts.

The 42x55 prop is 42mm diameter x 55mm pitch, that is a 42mm diam x 1.3 ratio = 55mm pitch.
