moving battery on 16' cruiser

[lloyds]

I am thinking of moving the battery from the stern up to under the port seat. It is about a 15' run of wire. Can someone look at their wire chart and tell me what size wire that takes? I have no idea how many amps a honda 50 takes to turn over. Thanks.

Make sure the wire you use is equal or larger than what is there, and if you splice they need to secure and waterproof . I Checked the rigging guide and they dont state the amp draw .
