I just got my kicker motor (Yamaha T8) installed for trolling purposes. My boat is a 21' center console with Evinrude 175 Ficht main engine.
My question is while trolling with the 8 horse Yamaha I will also be running my sonar and GPS for long periods of time. My concern is that the electronics will drain the battery while trolling with the main engine off. The 8 horse does have a 6 amp. alternator but that's not much. I have 2 batterys running through a battery selector. I guess while trolling I could switch to #1 battery and keep #2 fresh that way. Thoughts??
