I would like to report a broken housing due to a hard landing.  Actually, in
my case it was a wave on the water, same consequences.  Included are
pictures to show the details.  I use Tracy's redrive and adapter plate.  I
have one engine mount under the adapter plate.  The force  applied to the
mount applies a force on the engine rear housing right at the oil filter
boss.  My rear housing broke at the dowel hole next to the oil filter boss.
The new rear housing I bought is stronger in that area, there is more metal
around the dowel hole. One photo shows the broken housing and where I tried
to weld it.  One photo shows where the forces are applied. One photo shows
the new and old housings.

I am a bit skeptical that a hard landing caused this. In order to do that
all the other ten MM bolts holding the PSRU plate to the engine through
the spacer would have to deflect.  This dowel hole has been known to crack
in car use. That is why Mazda beefed it up in the third gen engine. What
type of intake system are you using? It is a four
port engine. Is it a turbo charged four port? NOS?

Did the engine ever back fire Rhino?
