CAD Update - REV2 (last update11/17, fixed duct thread issue)

I made an update to the CAD and added a bearing again. Here is the [complete REV2 assembly](http://a360.co/2hcQGrv). The only changed part is the [SealMount](http://a360.co/2heHmne). I’ll also post links in first post above.

Reason for this update is that I am trying to minimize vibration to keep the two shaft seals alive. This time I am adding a ceramic bearing on the wet side so it is even closer to the prop for max shaft stability.

Here some history on this setup:

Frist Parker 7:1 gearbox based design. You see I had a bearing on the inside (should have kept it):

This is the second Neugart 5:1 gearbox desing (current version posted above). I removed the bearing, added a thrust bearing close to gearbox. I wanted to minimize length and was hoping the shaft is short enough to be stable:

Now this below is Rev2, haven’t printed and tried yet. You see a bearing at the very outside close to prop. I just ordered this [ceramic bearing](https://www.amazon.com/gp/product/B01JKBUR1Q). Hope that stabilizes everything. If I would have a lathe here I would make a custom shaft with that 10mm pressfit bore for the gearbox output. These hobby shaft adapters are not the best solution but they work.
