Is one battery enough for 2 Engines?
I currently have 2 * 85amp batteries one for each engine, and the electronics run off one of the batteries. There is a slight drain from the electrics so im having to disconnect every time.
I'm thinking of moving one of the batteries (the older one) into the console to power the electrics and then wiring it to the other battery through an isolator. This will enable me to run the radio and sounder/GPS without worrying about being able to start one of the engines after and would act as a backup if the main one died.
Is 1 * 85amp battery man enough to run 2 * 60hp 2 strokes, they do both have emergency pull cords which i think i would be able to use if needed.
I'm trying to use things i have rather than buying a 3rd battery and trying to wire it up to the other 2.
I have thought about connecting the batteries together through an isolator switch but as the batteries are right by the transom i dont think a switch would last long.
