ABSTRACT OF THE DISCLOSURE A two-cylinder, two-cycle engine for an outboard motor includes a pull-rope starter unit and an alternator driven, capacitor discharge ignition system. The alternator includes an annular permanent magnet secured within a flywheel skirt and includes a pair of circumferential opposite poles with diametrical spaced neutral areas. A stator assembly is mounted within the annular magnet and includes a semicircular core with charging coil at each end. The coils are connected to charge a capacitor unit which is discharged through a con- trol rectifier. A trigger coil is connected to the gate of the rectifier and is mounted in coplanar relation between the charg- ing coils. The trigger coil is wound on a pole aligned with and spaced from the stator core with the coil and pole rotatably mounted by a housing having an integral cam for positioning a throttle lever. The housing rotates through a selected segment of the core. The outer periphery of the segment is non-circular to form an increasing air gap with advancing throttle spark position and thereby progressively increases the minimum RPM for starting of the engine, if the throttle and spark are ad- vanced BTDC. This ensures that the piston moves past TDC dur- ing starting for all throttle positions.
