Default submergered mako elec ???

poss buying a mako 250 1989, it was recently partially submerged for 6 hours. the motors are ok and the in side was not under but the wires to the bake were.. the marina and others say that the bout needs to be rewired..what does that entail and is it a diy type job or a marina job? i do all my own elec just did a new 200 amp panel so i am knowledgable...any advise helpful... i can get the bout for 6000. $ they ran the motors and all goodies worked prior to accident...went under due to bilge pump battery not charged by marina.
thanx all

I'd make a quick list of all the wiring your talking about. Are you looking at replacing engine controls?

Trust me on this. If you can work with a 200 amp service wiring without burning the place down or curling your hair on the steet side of the service then a boat is a walk in the park.

Think about it, make a plan, and do it. I did mine and have had no problems of any kind. I never rewired a boat but have lots of time with AC current.

The best part is that if something does go out, you know where to find it. Keep it neat and tidy. Don't skimp on cheapo wire and connectors. Buy only marine rated stuff (if you plan on holding on to the boat) for the long haul even though the factory did not use tinned wire.

There is also a book on boat wiring but I did not bother. I worked the entire project out in my head and went for it.

You can too.

2nd that. I've wired three boats no problemo, and I am no McGuyver. Key points here- 1. buy twice the amount of marine shrinkwrap and connectors than you think you need. 2. Buy a quality crimper and heat gun. 3. Use all 10ga wire- I know, overkill, but it is marginally more expensive and there are no questions afterward. 4. Draw your wire diagram before and follow your drawing. I have one boat that is over 5 years old and my wire job is perfect still and never had a battery discharge problem or any electrical gremlins. 5. Breakers, not fuses. 6. Use nothing from the old job, no matter how good it looks, replace the engine harnesses and get the starters and alternators rebuilt. 6. Before you start, go to see a new high end sportfisher and poke around the wiring for inspiration and ideas on technique. Believe it or not, it is fun to do and it will give you the confidence in your boat you need to head her out to sea. DIY for sure! People on this board love to help, feel free to ask questions.

HeHe I can never draw a diagram and then go wire it. [Not a detailed drawing]

It's all in my head. I wire it and then make a quick sketch drawing and then bring that in the house and draw it with a program called Smart Draw 7.
This way I can get the exact screw on the buss bar that the circuit is hooked to.
Understand that the pix below is only one small section of the wiring that is done to this boat and the boat has a lot more circuit's and trick stuff than your average center console boat.

Here's a example. This is the 2- bildge pump's and High water alarm w/ a ON/OFF switch to kill the alarm when the S#*t hit's the fan, so it's not driving you nut's in a already stressful situation.
