Abstract
A marine outboard engine for a watercraft is disclosed. The marine outboard engine includes a starter motor operatively connected to the crankshaft of the engine and a capacitor electrically connected to the starter motor. The capacitor is powering the starter motor to initiate rotation of the crankshaft. An alternator is operatively connected to the engine and is electrically connected to the capacitor for charging the capacitor when the engine is operating. A starting system and a method for operating a starting system of a marine outboard engine are also disclosed.
Claims12
A marine outboard engine comprising:
- a cowling;
- an engine disposed in the cowling, the engine including:
- a crankcase;
- at least one cylinder connected to the crankcase;
- and
- a crankshaft disposed in the crankcase;
- a driveshaft disposed in the cowling generally parallel to the crankshaft, the driveshaft having a first end and a second end, the first end of the driveshaft being operatively connected to the crankshaft;
- a gear case operatively connected to the cowling;
- a transmission disposed in the gear case, the transmission being operatively connected to the second end of the driveshaft;
- a propeller shaft disposed at least in part in the gear case generally perpendicular to the driveshaft, the propeller shaft being operatively connected to the transmission;
- a bladed rotor connected to the propeller shaft;
- a starter motor operatively connected to the crankshaft of the engine;
- a tiller operatively connected to the cowling;
- a capacitor disposed on the tiller, the capacitor being electrically connected to the starter motor, the capacitor powering the starter motor to initiate rotation of the crankshaft;
- and
- an alternator operatively connected to the engine and electrically connected to the capacitor for charging the capacitor when the engine is operating.
A starting system for a marine outboard engine comprising:
- a tiller having a first end a second end;
- a throttle control disposed at the first end of the tiller;
- the second end of the tiller being adapted for connecting the tiller to the marine outboard engine;
- a capacitor mounted on the tiller;
- a starter motor connected to the capacitor;
- and
- an electrical connection electrically connecting the capacitor and the starter motor.
