Thanks all for your helpful suggestions!
I took the power head off again (getting good at that now 😉) and sprayed water through both the incoming and outgoing port of the power head. Enough water came out to rule out a blockage.
Until now I only focused on the impeller side of the lower unit, so to be sure I also checked the exhaust part. Again, no issue found.
So to summarize, everything seems to work as it should, until I bolt on the power head. Then I have a few seconds of water until the water flow stops and powerhead starts heating up.
My money still is on the gasket, although I’ve checked it multiple times now and cannot find anything that stands out.

Tomorrow I will try to poke the holes with some trimming wire, but I have low hope for that.
