I have a 4 battery setup on my boat. Twin Yamaha F150's. Each engine charges a Duracell AGM 34M starting battery. Both engines have a charging shunt installed. One charges a Duracell AGM 27M for house and the other charges a Duracell AGM 34M for bow thruster, windlass and bait pumps. The 4th battery is installed in the bow near the bow thruster and was not installed by GW. The other wiring in the aft compartment is standard GW.

Yes read this. Separates the House from the Start batteries and uses Aux charging cables from motors.
