Page 28 of the RANGER manual fourth paragraph says that we have to provide the device that pushes water through the pipe and that it must be an integral part of the rov not an independent device.

propeller shrouding

is there a guideline for how much shrouding is needed for a prop?
Does it just need to surround the sides of a propeller or does it have to have a grate over the front and rear as well?
thanks
