Thank you for allowing me to assist you, my name is Joe and I will be happy to assist you with your concern today.
The motor electrical wiring would be the only thing complicated and with any type of a diagram per say, the rest of the electronics are all powers and grounds, etc and is just a matter of knowing how to correctly wire 12v systems. You will want to go from the battery/switch to a buss bar as well as fuse panel or breakers and then to each circuit device. For instance an bilge pump let's say has 3 wires, one is ground, one is manual on and the other is switch whereas a 2 wire pump is power and ground the power going to a flat switch then out to pump and an additional manual power from a switch on the dash to the pump side of the pump circuit. This goes for anything electrical, you will have switches on the dash and these work with a main power into the switch and then another out that goes to the device it is to control, grounds go from a buss directly to each device.
It really comes down to what exactly needs to be rewired as to what repairs will need made but you will not usually find a electrical diagram for these esp on this year with the exception of the control assembly/ key switch and engine.
I can help you step by step re-wire each circuit or the entire boat but I need more info from you on what is needed.
