Running 2/0 cable fromt the batteries to Switch ...

I'm thinking About running 4/0 from the common on the switch to the Transom and then spliting to 2/0 to each motor.

Also 2/0 Neg from the Batteries To a bus bar then 4/0 to the transom and then spliiting to 2/0 to the motors..

The only negitive I can think of is if the 4/0 failed somewhere your screwed ...

You only start one motor at a time ..The 4/0 would help voltage drop and would simplify the rigging ....

The 4 gang bus would have a 2/0 from each battery, a #4 to the house load, and then the 4/0 to the transom where the 3 gang would split to each motor with 2/0 .....

Thoughts ? m
