My boat starts and idles great but when I get up to 1200-1400rpm it it Boggs down. It’s a 2006 Mercruiser 5.0 MCM. I’ve sprayed a mist of fuel into carburetor intake and nothing happens so I’m thinking it’s in the ignition system. I’ve put new plugs/wires cap and rotor. Looking at the coil, I have 12v with key on. 13.7 while at idle on both the wires. Is this coil externally resisted?
