Re: [electricboats] Motor Mount and Thrust Plate design - hoping for feedback

I was thinking you needed that 90.  I might move those spacer blocks between the motor plate and the thrust plate more inboard.  As much as possible while still leaving room for the hub/bearing.  And if you put a 90 on one edge of the thrust plate I would put it on both so it doesn't want to twist.  Point is to stiffen the thrust plate and do it uniformly.  Maybe make it from some c-chancel?

Also, I think ideally your mounting to the beds is in the same plane as the axis of the prop shaft or as close as you can manage.   Otherwise you create a moment where the thrust of the drive is trying to bend the whole assembly rather than pushing in line with the mounts.  I made a sketch that explains that better.

All that may be easy or difficult depending on the geometry and available space for the everything. 

What is the boat made from?  Fiberglass?  Steel?

Carsten, thank you!  I'm planning on having the plate itself be 1/2" stainless steel - very heavy and sturdy. And all of the supporting items 1/4" stainless steel. What's not shown is that the 'thrust plate' will also have a 90 bend at the bottom to provide additional support to handle the thrust forces.
