Jeff this step file should import into solid works OK.
If you have trouble doing this let me know.
I did not fillet the bottom of the pockets as Rhino does
not do that well. Just use a 1/2 inch ball mill for the pockets.

I think the best approach to the spacers is use 1 inch
round aluminum bar stock and tie them together with
tig welded 3/16 sheet. Two are counter bored for
the hollow dowel pins. For a fine touch the sheet can
be rolled on a 14 inch radius. This, I think, would be the
lowest cost way. Putting the motor mounts on the plate
relieves the spacers from the 600 ft pound prop torque.
The only thing the spacers see is the 200 ft pound engine torque.

The counter bore on the back side is a per Tray's instruction
to hold his shaft seal.

Be a good idea to make one set and see if it fits a
end housing. If you don't have one I can have Mazdatrix
ship you a junk end housing.

The Barry cup holder stp file will follow shortly.

Paul

this STP.  file did not show up.just gibberish. Maybe try another
  type.....
  jeff
OK Jeff Here is an iges file zipped.
What version of SW are you running Jeff?
Jarrett would you please try to load that stp file in SW.

Paul Lamar
There ya go..

 Jarrett

 Thanks Jarrett.
 Try this Jeff.

 How does the SW rendering look Jarrett?
 Was everything OK?

 Paul Lamar

Yup, I tweaked the 'visual' stuff so it was easier to see [changed
the color] and checked it for surface errors fixed a couple and
then made sure it had resolved it as a solid body before sending
it back [sounds more in-depth than it really was :) ]

Jarrett

Thanks Jarrett.

Here is the Barry cup holder. To be tig welded on the
ends of the motor plate. I simplified it some what to cut cost.

Both stp and zipped iges.

Jeff, we will need two of these for every motor plate 2.5 inch OD
6061 T6 bar stock is fine as is for a finish. It is the thick
mounting for the Barry rubber bushings.

Jarrett please check these as well.
