Well crap, my 2019 Outback Mirage drive 180 started making more noise today. I thought I had it fixed by loosening the cables a tad and it was quiet for weeks until today. Things I have done already: I have lubed the pedals, it still made the noise if I pushed the arms instead of the pedals. I took the drive out and washed it in the water next to me. Shouldn't have to use any grease as per Hobie instructions. I put the drive into the Outback and it makes noise, take it out and actuate it and no noise. The pressure of pushing the water with the fins seems to contribute to it and the hull amplifies it.
I disassembled it about a half year ago because it was making some real nasty noises. Found a Delrin bearing in several pieces and a slightly flattened bearing too. Used grease sparingly putting it back together and it worked fine for a couple of months. Started to make some minor noise then adjusted the cables a little looser and it went away. I use it one to two times a week in fresh and salt water. Don't put my foot into it accelerating. I'll check some things this morning and if not obvious, I'll tear it down again. Video of noise:
