Any of you guys know if we can do the timing on a 1999 5.0 efi merc without the merc scanner?
Mercruiser manual says you need to plug the scanner and to adjust to 8btdc. Don?t know why we need the scanner do.


Thanks

Andr?

Re: Timing???

You can set base timing by jumping terminals "A" and "B" on the Data Link Connector (DLC), this puts the engine in Service Mode. Then set check/adjust timing using a common timing light.
