Shop manual on my 98 502 says " use marine scan tool to put into service mode".

Anybody know if there is a way to set base timing on these engines w/o a scan tool?

Thanks!

It's been so warm, I can't believe the boat is not in the water yet!

In the distributor wiring harness near the distributor is a purple wire with a white stripe it is approx 4" long pigtail that is not connected to anything and has a brass female barrel connector with a clear rubber boot on it, ground it and you will be in base timing.
