I believe Hobie is currently greasing them with marine axle grease. Apparently they originally were not going to grease but found that they had a tendency to squeak over time. The potential for grit and grease is no different than with the older Drives-- rarely an issue. I understand Hobie has tested these extensively both with and without grease with no accelerated wear problems either way. Delrin is pretty tough stuff (is also low friction).
Speaking of a squeaky GT drive, I made a brief video of mine:

In particular, there does not seem to be any noise coming from the bearings rubbing against each other. I haven't used any grease, but I'm skeptical that that'll solve the problem without constant re-greasing, which requires taking the chains off. It seems to me that a "squeak-free" fender washer (stainless? nylon?) between the drum and the spine would be a more permanent solution. Anyways, I'm open to suggestions. Thanks.
