Battery
Refer to the specific instructions and warnings accompanying your battery. If this information is not available, observe the
following precautions when handling a battery.
!
WARNING
Recharging a weak battery in the boat, or using jumper cables and a booster battery to start the engine, can cause serious
injury or product damage from fire or explosion. Remove the battery from the boat and recharge in a ventilated area away
from sparks or flames.
!
WARNING
An operating or charging battery produces gas that can ignite and explode, spraying out sulfuric acid, which can cause
severe burns. Ventilate the area around the battery and wear protective equipment when handling or servicing batteries.
Battery Precautions for Multiple Engines
Alternators: Alternators are designed to charge a single battery that supplies electrical power to the individual engine on which
the alternator is mounted. Connect only one battery to one alternator. Do not connect two batteries to the same alternator
unless a battery isolator is used.
Engine Control Module (ECM): The ECM requires a stable voltage source. During multiple engine operation, an onboard
electrical device may cause a sudden drain of voltage at the engine's battery. The voltage may go below the ECM's minimum
required voltage. Also, the alternator on the other engine may now start charging. This could cause a voltage spike in the
engine's electrical system.
