Oh yeah. And I had an Aquadrive fail. Bellows burst. Grease all over.
Replaced it (with one I bought from Hansen) and eventually realized the shaft strut was misaligned. The thrust bearing mount was offset. The engine was misaligned. The shaft was bent.
After digging out and rebedding the strut, having the shaft/prop/coupler trued, remounting the thrust bearing and aligning the engine it all ran smooth as silk.
I don’t know, but would not be surprised, if the alignment issues were the cause of the failure at about 2700 hours.
Btw, it was clear that the misalignment was not a factory issue, but later work
