Boat Info
1989 Amberjack 270
Engines
twin 4.3
newly purchase boat, bought 2 new batteries as there were none with the boat. there are 2 battery trays, 1 perko battery switch, for a single battery. were these from the factory installed with a single starting battery and a single for house. anybody that has a similar twin engine boat i would love to see a picture. Also from the wiring harness there are 4/5 8 gauge red wires (obviously the hot side). Where these attached to distribution block, or were they all attached to the positive battery terminal. thanks in advance for any help
 
Best option is to have dedicated starting battery for each engine and dedicated house batteries.
