Our order of two coils arrived promptly. The coils were as described and fit the Johnson outboard. When we first installed them, they rubbed on the flywheel. We pulled the flywheel,loosened the mounting bolts, pushed the coils in tighter, tighten the bolts,checked points gap, and reinstalled the flywheel. Then, the flywheel turned smoothly. The engine fired up fine. The coils have been in use for a few weeks now.
