Took boat out and ran fine until I stopped for one last bass attempt, and didn't fire at all. When removed cal at house I discovered all 6 coils were fried and the filling comming out. Replaced all 6 coils and now it will start after great effort but misses badly. All 6 coils test good but where to go from here and what would cause all 6 coils to go out at once. No, hasn't been run hot.
