tions for your area.
1. Select a battery that meets all of the following specifications:
FOR OPTIMAX ENGINES –
a. 12-volt marine type.
b. 1000 Marine Cranking Amps (MCA) or
750 Cold Cranking Amps (CCA) minimum.
c. Reserve capacity rating of at least 105 minutes.
FOR Carbureted and EFI ENGINES –
d. 12-volt marine type.
e. 670 Marine Cranking Amps (MCA) or
520 Cold Cranking Amps (CCA) minimum.
f. Reserve capacity rating of at least 100 minutes.
2. Select proper size positive (+) and negative (–) battery cables using chart. Battery
should be located as close to engine as possible.
IMPORTANT: Terminals must be soldered to cable ends to ensure good electrical
contact. Use electrical grade (resin flux) solder only. Do not use acid flux solder, as
