That motor cranked so fast it nearly tore the transom off.

2/0 is big.....from small to big..14awg, 12awg,.....6awg, 4awg, 2awg, 1/0, 2/0 and so on....2 and 4awg is typical for a short run battery cable....but using the load charts is the best way to pick the right size....the distance is always measured round trip, not one way..

I was told by a wise man from the north to use #2...so I used #2...seems to be the choice from FL to NJ...
