[Kevan]

Kevan, you have answered the sperical bearings question, thank you.....but the way your post described how the motor position/height could be changed(raised or lowered) because the fixing screws and the motor bearing had a slot to move in, in the end of the pod....am I correct in that understanding? and if so ....I asked what else supports the motor? just the screws?

I think Kevans motor pods are similar to mine,
maybe this photo makes it clear

The motor is fixed height ,the axle can move up or down,the bushings beibg driven by 2 screws .

It was your idea I liked enough to steal
