Charging Minn Kota Battery from Crank Battery Using 25 amp DC to DC Charger.

[Thegibeno]

I wish to charge my 120Ah Minn Kota Battery from my Crank Battery. I have a 60 hp and was going to use some sort of DC to DC set up.
Would the alternator in my outboard be enough to charge the crank and then top up the Minn Kota battery??
Thanks in advance.

That depends on the run time for your trips and how much the Minn Kota battery is drained. When it's drained completely it could take some time to recharge it. A couple of hours with the full capacity from your alternator. If you use your crank battery then it could be drained by the Minn kota and your not able to restart your engine. So a lot of variables to give a complete answer.
