500 EFI timing
 

We rebuilt a merc 500 EFI and need to know the base timing specs and timing procedure for initial start up.
Thanks for your help:cartman:

Take the cap off the diag. plug at the rear l/h side of the engine, you need to connect a jumper wire between the
black wire and the black/white wire.

That puts it in base timing mode, 8* is the spec.

Thanks Jaay Teee that should get us there
