    I never see anything about using a kortz nozzle on any type of electric motor. Would not using the nozzle be very effective at increasing thrust:?:
    I know several companies make prop guards that supposedly increase thrust, but are their claims legit?

    Seems like putting a torqeedo or other powerfull motor in a kortz nozzle would really put out some thrust. Please steer me to a previous thread if there is one or let me know what you all think. Thanks.

    You use a nozzle to reduce induced drag on a prop in highly loaded applications. The idea with electric drives is to design props that do not have heavily loaded blades. Once you do this a nozzle is a disadvantage due to the added drag of pushing the nozzle through the water.
