f25 battery cable gauge

hello,

i want to relocate my battery further fore in my boat. i dont want to splice the existing battery cable so i will just replace them.

i cant find anywhere in the manual how much the motor draws when it cranks.
i also cant find the gauge of the existing cables.

the length of the cables will be 9'. What gauge cable should I use?

It has 4ga wire in it, may have to go with 2ga if going extending it.

thank you!
