In addition, the engine is an essential part of the boat’s electrical system; it both generates
and consumes power.
If you connect or disconnect the battery, take care not to touch both battery terminals with
a metal object at the same time.
Only recharge the batteries with the boat's battery charger or one with equivalent power.
Charging the battery with excessive current creates an explosion risk.
Do not alter the onboard electric system or relevant drawings; alterations and maintenance
work have to be carried out by a professional.
