Welcome to the site...as mentioned by my esteamed colleauges above, pictures of your boat are always appreciated...and I can tell ya the good, the bad and the down-right UGLY show up here!!...
I'm in the process of doing what you're about to do...my engine wiring will remain as is...the positive lead will remain to the battery SWITCH(thanks for turnin' on the light, Pete) which will remain in the transom...and the negative will be to a post in the transom, then from switch and post to batteries up front w/#2 gauge...the 00 Ridge mentions above will certainly work as well...as mentioned, the cost of copper is high these days...I dropped about $80 on 22' of #2 and $35 on some smaller stuff for the elec motor...and I got a couple of other things to cover cuz I'm making a new hatch thru the floor to hold the 3 batteries...will be postin' pics soon!!...might today if the rain holds off down here...
I agree w/Ridge on the bracket & full tranny combo!!...
