Electrical Equipment
The electrical equipment of your STEYR MOTORS Marine engine primarily consists of an alternator with transistor-
ized voltage regulator, battery and all necessary connecting cables and leads.
Alternator
The alternator is driven via a poly-V-belt resp. serpentine belt from the 4 cyl. engines and via a V-belt from the 6 cyl.
engines and charges the battery at all engine speeds. Output at idle speed is ~ 30 A/12 V and will rise with an engine
speed of 3,000 rpm to maximum output of 90 A/12 V.
Optional:
The 6 cylinder marine engines may be equipped with an optional 80 A/24 V alternator and DC/DC charger system kit.
Battery
FOR ALL 4 CYL. MARINE ENGINES
Use a 12-volt battery with a cold testing circuit of 450 A at –18 °C and a capacity of 92 Ah at 27 °C, to ensure the
supply of the electric and electronic components at all operating conditions.
FOR ALL 6 CYL. MARINE ENGINES
Use a 12-volt battery with a cold testing circuit of 650 A at –18 °C and a capacity of 115 Ah at 27 °C, to ensure the
supply of all electric and electronic components.
