Wiring my boat

Ok so I have a 21 ft venture from 1978, we went out this weekend and I couldn't get the outboard to crank so I ran the trolling motor when the wind died. After about 4 hours of running my battery was completely dead. So I am looking into creating a power supply to run more than just the trolling motor and outboard. Does anyone have a good diagram? I have no electrical system in this boat what so ever. I will be wiring a VHF radio, cd/radio, 4 speakers, GPS, and the motors. Can you guys help me at all? Any info would be greatly appreciated! Photos, diagrams, whatever. I wanted to use solar power to charge my battery banks but I'm all new to this boat thing. I have don't plenty of car working before.

Get a good book on marine electrical such as this one:

Boatowner's Illustrated Electrical Handbook eBook: Charlie Wing: Amazon.ca: Kindle Store Boatowner's Illustrated Electrical Handbook eBook: Charlie Wing: Amazon.ca: Kindle Store

It will give you everything you need.

Re: Wiring my boat


Not sure how far along you are here but as a music enthusiast, I'm wondering about the four speakers. Just FYI (or you may already know) if you are playing music in stereo (and not mono) and have two of the left or right channeled speakers facing the same direction or in relatively close proximity, it can sound unpleasant because of the identical waves overlapping. I'm thinking you're doing two speakers in the cabin and two in the cockpit in which case, you should be able to fully power one or the other and not both.
