ive got a interstate battery, 340 cold cranking, 450 cranking amps.

I also have a holly red fuel pump producing the fuel.

I am unsure what the charging system puts out on the 56 cube omc, do you think it would be enought to handle the fuel pump. I dont have anything else draining power except trim/tilt.

If i put it on the charger every so often, it should be alright, right?
