Battery
Check the battery electrolyte level and check
that the battery has sufficient power to start
the engine easily. Recharge the battery or re-
place it if it is not in good condition. (See page
99 for battery recharging procedures.)
Also, check that the battery leads are tight-
ened securely and that there is no corrosion
on the battery terminals. Check that the
breather hose is securely connected to the
battery and that it is not pinched.

The battery must always be fully
charged and in good condition. Loss of
battery power may leave you stranded.
Never operate the watercraft if the bat-
tery does not have sufficient power to
start the engine or if it shows any other
signs of decreased power.
Be sure to connect the breather hose to
the battery. Fire or explosion could re-
sult if the breather hose is damaged, ob-
structed, or not connected properly.
