Thread subject: Whaler Central - Boston Whaler Boat Information and Photos :: Need Ideas for battery set-up for twins

I used to have a 17 Outrage with a dual battery set-up, and big 1-2-Both-Off switch. Now I have a 1990 18 Outrage, standard console, with twin 70hp Yamahas. I plan on rewiring. The batteries are in the console. What size of battery wire will provide the smallest voltage drop? Should I have 3 batteries? What do I need to charge the batteries while they're in the boat with an extension cord. What switche(s) and other items do you suggest. I plan on cutting holes in the console floor for battery boxes -- to take the weight off floor and also give me more space in console.

Electronics: Vhf Radio, GPS, Stereo, Amp, Bilge Pump, 12V Outlet.

A list of specific items and manufacturer would be greatly appreciated. Thank you.

Here are some photos of my progress:

I've removed almost all the metal items from gunnels in preparation for sanding.

I've removed almost all wood for refinishing.

I removed all canvas for storage and some minor repairs.

I removed previous owners reg numbers and stickers.

Removed transducers for depth finder and fish finder. I'm planning on selling these items and Garmin 182C on eBay and getting a GPS sounder to replace previous.

I will be replacing all fuel lines, control cables, battery cables and more.

I think this will be the perfect time to lift deck, inspect, clean, etc.

Tomorrow I will try to sand gunnels, and teak piece on top of console, and apply first coat of teak oil. It's supposed to be warm -- we'll see.
