What is the min battery for an evinrude 1988 90 hp e90tlccr motor to start and also run a bilge pump?

For a 1988 Evinrude 90 HP E90TLCCR motor, a minimum of a 12-volt battery with at least 600 cold cranking amps (CCA) is recommended to ensure reliable starting. Additionally, the battery should have sufficient capacity to power a bilge pump, which typically requires around 10-20 amps, depending on the model. A deep cycle battery rated at 100 amp-hours or more would be ideal to provide adequate power for both starting the motor and running the bilge pump.
