Yamaha F350 Battery Cable Questions

[nghtrn99]

'm repowering with a set of 2009 Yamaha F350's and they did not come with the OEM battery cables. Yamaha wants $700 each for them and I'll still have to get an additional 20 feet of wire to go to the batteries (they are only 10 ft long).

What gauge battery cable do I need to go 25 feet from the batteries to the engine?

Where can I get the lugs for the positive and negative terminals that connect to the motors?

25ft is a 50ft cable run.
its simply to far.
look in the rigging guide and the wire size and maximum wire extension is there.
the lugs can be ordered from boats.net or any yamaha dealer.

I haven't been able to get those lugs through boats.net or a Yamaha dealer.
Do you have a part# for them?

Wiring

I would go to my nearest hardware store or bigbox store to get my wire and/or terminal connectors. Wiring amperage and voltage info is easily accessible on internet
