Starting Battery

Featured Replies

Currently have a 27DC-6 as my starting battery for a 150hp Yamaha. Haven't had any trouble in the cpl months I've had the boat but am wondering if this is the right battery for the job...

Keep it charged and run the crap out of it. It's pretty much a dual purpose battery so you should be good.

720 Cranking amps should be more than enough for a 150 Yamaha. If it has probablems suppling enough cranking amps, your electonics will be shutting off when you crank the motor. Even if that happens, you need to double check and clean all battery and terminal connections before blaming the battery.
