Today I picked up the stainless steel propeller from Grasser and fit it to the motor. It fits perfectly! It hangs down to about 5mm above the temperature sensor of the Silvercrest - I was a bit wary when measuring, that the rod would be too long and might touch the sensor. It was perfectly built, though. There is about 10mm space between the outer edge of the blades and the Silvercrest wall. This should be perfect. One thing I have to check out is whether the motor is bi-directional. If it only goes in one direction, a problem might arise that the propeller rod would screw itself out of the M8 socket. If I can make the motor go the other way, this won't be a problem as the rod would tighten itself.
Yesterday, I faxed the brew registration to the Hauptzollamt in Landshut - 23l of 13°P wort. So everything is set up and ready for Sunday.
