This is a Kort Nozzle for a homemade ROV thruster made from a Mayfair 750 GPH Bilge Pump.

Adding this kort nozzle to the thruster will increase the output thrust by about a full pound. This nozzle was specifically design to work with a 3 blade 50mm Robbe Boat propeller using an adapter with these specs.

This was a prototype and the nozzle arms are a little weak so I have since made a new version. that incorporates a mount into the nozzle. This version works for upgrading existing thrusters so I thought I'd share it too.

This nozzle was specifically design to work with a 3 blade 50mm Robbe Boat propeller using an adapter with these specs.

STL prints as positioned with minimal supports. Even printed at 100% this will probably not be waterproof so keep that in mind when it comes to your Rov's buoyancy.

Custom Section

The kort nozzle/thruster combo was designed to be mounted using a 1 1/2 conduit clamp.

The conduit strap is mounted to the Rov frame using a #12 stainless steel flat head screws. Using a flat head screw allows the mount to self center to the mounting hole.

It can be mounted to a flat or round surface, (PVC frame in this case) the area around the nozzle must remain open though for proper flow.
