Boat ran fine then fell on it's face and had no power. wants to die at idle in the water. I found that I had no spark on 1&3. I replaced the stator, trigger, both switchboxs, both coils, and new plug wires. Plugs, wires, connections and coils are ohming out great. At idle I'm getting 40v on the "red" low side and 120 on the "blue" high side I'm stumped. Please someone smarter than me help...
