Last Sunday Andy and I had similar crashes which destroyed the motor box on the 62" span E-Flite Beaver. Mine has a Power 25, Andy's has a Power 32. The crashes happened about 5 minutes apart.
Rebuilding the motor mount.
Any re-build has two steps:
step 1- assemble everything with proper alignment and glue in place. Do not worry about strength.
step 2- re-enforce everything to make it strong.

Repair:
step 1- put oil on the motor screws in case epoxy flows onto it. Photo 18
step 2- glue the motor onto the firewall. Clamped in place. Photo 19
step 3- glue fibreglass over the breaks and let cure. Photo 21 Note- trimming is done later.
step 4- cut the excess cloth with an X-Acto knife. Photo 22
Done!
