Looking for a little help. 1976 Merc 850 Thunderbolt Type V ignition. Looks like it is setup to utilize timing, but everything I’m reading says the switch box collects and distributes the signal for spark. Any idea if this engine should be timed?
So I've completly rewired a 76 Thunderbolt 85 HP. I've tried installing a Tach and am getting no reading. I have researched and researched and have had no luck. I know it is a brown wire, but not sure where I need to put it. Any help is appreciated.
