224 Battery relocation/Rewire

[RMatthews76]

Greetings,

I am planning on relocating the batteries on my 224 to under the console. Can anyone who has done this give me an idea what gauge wire they used for the long run from batteries to motor. I've searched and googled for a specific size but have found people recommending from 6 gauge to 2/0.

I'd say with bends and making it look nice give or take a run of 12 to 15ft maybe less on

2 group 31 Deka AGM's going to a 98 Evinrude Ocean Pro Carbed currently but might step up to Merc V8 in the future so id like to do it right the first go round if that is possible.

Thanks in advance for any assistance.

I have 2-ga for mine. It was done from PO.

You'll get LOTS of opinions on this and this is one area where if you can afford to overdue I think you should. I rewired my 224 and moved batteries 2 years ago, here I was told to use more and on other sites I was told over kill. My '04 DI Evinrude take lots of juice to turn and I went with 2 AWG. I climbed on many new boats at the boat show just before I started the project and there wasn't a single boat in my size range (high end or low end) that used wire as heavy as 2 AWG. I do not recall exact length, but was close to 17'. It was the right choice for me b/c my rigging tube is beyond maxed out. If I would have used larger wire I would have been forced to get creative in the back.

I haven't done anything since but replace the batteries, and have never had an issue.

Awesome, I must have overlooked that posting. Thank you both for the confirmation. I was really going overboard, 2awg is a little easier on the budget than what I actually thought I was going to have to use.

Remember that the calculation is based on total run length so are you saying 12-15 ft which would be 30ft total. Based on the Ancor wire sizing calculation 2AWG with 3% voltage drop works for 15ft run total. Based on running wires in crowded rigging tube I prefer to error of the safe side. Have you ever jumped started a car with undersized jumper cables? The cables get hot right? I'd consider using #1/0 AWG with a safety factor knowing if you upgrade to that Merc which are high torque you would be good.
