Well I've gotten myself into a right mess with the engine mounting bolts in the Alberg.

The aft port-side bolt was cross-threading in the embedded aluminum nut/insert so I chased the threads today hoping to fix it up and keep going. Well laying on top if the engine while trying to use the tap I ended up making it worse and now the 3/8" bolts won't engage at all.

My options as I see them:

1/ have the yard remove the engine and go back in drilling out the stringers for either:
- fill with epoxy and tap again for 3/8 bolt
- drill and tap for a 1/2" bolt
- use a hanger bolts (lag bolt on one side / 3/8 regular bolt on the other)

2/ leave the engine in place and using a 90D drill prep for options above or drill and switch over to a basic lag bolt

Another option I may be missing did to my frustration ?
