I replaced my 1994 blown Force by Merc 70hp powerhead with a 1997 75hp powerhead. Everything fit except the the flywheel which I replaced. I understand the igntion system is different, is there any way to set the older ignition to the 75 hp motor? Getting backfire.

After checking fuel delivery and resetting timimg, motor started and idled no problem. Runs in the tank, we will see how it does in the lake.
