ABSTRACT:
A rewind type starter apparatus for an outboard motor is mounted on the side of an internal combustion engine having an inverted cup-shaped flywheel secured to the upper end of the engine crankshaft. A protective cowl encloses the engine, starter and other engine components. The starter apparatus includes a mounting plate bolted to the engine block through a pivot tab and slotted pivot openings. A coiled, flat spring encircles a helical shaft attached to a rope sheave and rotatably mounted on a fixed pin extending laterally of the bracket and engine. A rope is wound within a groove in the sheave which is spring-loaded to the wound position. The outer end of the rope extends outwardly from the lower periphery of the rope sheave to the front of the cowl. A pinion gear includes a hub member located on the shaft with an internal complementing helix drive between the shaft and hub. A cap holds the shaft on the pin and limits the outward movement of the pinion gear to engagement with a driven gear formed on an inner portion of the lower edge of the flange of the fly-wheel. A small guide pin is located within an opening in the pinion gear with a U-shaped clip frictionally, slidably located within a peripheral groove in the cap to slightly retard gear rotation and effect lateral movement of the pinion gear into, and out of, contact with the driven gear.
