Default Propeller for a new airboat, question

Hi:

I want to build an airboat with the same performance as the Aquacraft Mini Alligator tours, that comes with a brushed 380 and a 5.5 in. propeller, directly coupled to the motor.

The propeller pitch is not specified, anyone knows about it?

I built a 3.5:1 gearbox for an Electrifly that runs at 27000 rpm on a 2S li-po pack (7.4V), so the propeller will turn at around 7700 rpm.

Thanks,
Robert
