Some pushers have enough width to use the side flanges on such a

housing.

However others do not, due to a very narrow rear pylon or cowling

areas.

In these pusher situations, the aft mounts have to be very narrow

(about

13") or even a single mount.  Having mounting bolt holes at a 6:00

starter

and options nearby would provide for a simple mount in this area:

just

bolt it on.  There is plenty of room for the starter at 6:00.  I was
thinking that the wide sides of the bellhousing could cut be cut off
outboard of any structure needed only for the side mounts.

It appears the latest bolt hole/fin design might put more structure

right

in the 6:00 position, which would certainly prevent putting the

starter

there.

******No Scott, I believe you've got it backwards!!!......The Bellhousing
style on the RIGHT of attachment "Comparison", Is the final choice, as it

is

stronger and weighs the same as the one on the LEFT.....

Paul failed to post the attachment in my reply to you, which shows my
preliminary L/O for a 6:00 o'clock Starter Blister. I've re-attached it

here,

as you can see it's got the room.

I understand the "right" drawing does not have a fin at 6:00.  I didn't
understand it was the best current design, sorry.

As long as the housing has enough area to accept a starter at 6:00, and
hopefully at least two other locations for bolts on the same end of the
housing for additional mounting bolts, it would seem perfect for
narrow/pusher applications.
