Battery cable size?

[mgarvie]

I'm considering relocating my batteries and the more I read about sizes the more I'm confused. I have a Yamaha 60hp 4 stroke and I am having no luck finding how much current the starter draws. The distance from the battery switch to the motor would be around 17 feet (34 feet round trip). Opinions?

A sort of ball park estimate is around is 250 amps for the starter, and for that long of a run at least a 1/0 cable.

Here's the link to a voltage drop calculator that should help.

Thanks for the information. Looks like the price to move the batteries isn't worth it. Think I'll order some vinyl flooring instead.

Here is the chart I always use. It is nicely explanatory. And it agrees with James at 1/0...ish.

Yea that was a very generalized guess
