The mounts for the cowl are just 1.5mm stainless steel that I cut on the band saw, drilled on the pillar drill and bent with a good old hammer in a vice!
You can just about see the oil in the tube coming out of the back of the thruster.
My test tank is struggling with this size of thruster in there as it stands but I still managed to get some good runs and readings.
I was seeing over 1.5kg every now and again, which equates to about 750g of thrust in a far from ideal environment for the propeller, from a water flow perspective, so I'm pretty happy with that :)
I'll do some further tweaking and maybe see if I can find a bigger plastic container to use as a tank.
I'll also turn the thruster around in the tank and see what thrust I get in the opposite direction too.
