Expensive ones?

They look like covers that go over the standard ones to prevent the driveshafts from coming out in a bad knock to me. Quite a good idea, but could lead to bent driveshafts.

I dont remember who made those but I remember when the SX first came out there was a huge problem with the standard lightened outdrives and I believe this was someones fix for the problem until schuey reworked the design and hardening process

They are some bits that Schuie tested, but never made it to production.

I wonder if these would fit, from the Mi4CX :)
