Timing on 500EFI

Can someone please tell me where the timing should be set on a stock Merc 500 EFI.

Thank you

36 degrees. If you don't have a scan tool jump pins A and B on the DLC connector to put the motor in base timing mode. Set the timing to 8 degrees then verify its going to 36 when you rev the motor up to ~3500.

Was thinking that it should be around 32 to 34 degrees but did not know for sure.

Re: Timing on 500EFI

I've never done it with a scan tool. If you're at 8 in base you should be fine.....the "plate" with "500EFI" and all info on top of mine call for 36 degrees right on them. Could have something to do with needing a load?
