I’ve got a used Avast Marine K1 Kalk Stirrer. I ordered a replacement Motor and shaft coupling. These have been installed this morning and tested. I’m selling this for $175.00 USD. Local pickup only. I’m located in Rancho Santa Margarita (92688).

Pictures and video testing below:

The unit is a couple of years old but has been in storage the past year. The motor block went out. I finally purchased a replacement from Avast Marine. I’ve installed the new one this morning…

the unit now also has a new shaft coupler I installed as well:

The full unit here is put together. I taped the lid over the motor to keep in place while I’m storing it. But in use I don’t seal this but you can if you like with just some silicone.

I have used various reactors and schemes for kalkwasser dosing over the last 30 years and the avast marine (K2 in my case) has been unmistakably the best solution. Been running mine for 1.5 years.
