Mercury V6 175 outboard stator issue. What are my options?

Hello fellow Mercurians.
I am restoring '76 V6 Mercury outboard and, while testing ignition, I found that one side of cylinders has no spark. I checked resistances on stator and on switch box comparing between working and non working sides and found that blue/white wire from stator is open connection. Other wires are according to the service manual. I pierced insulation right at the stator and still no connection, so I concluded that wire or coil inside stator is burnt or broken.
Buying new stator is best choice, but they are quite expensive.
Did anybody here try to open it and rewind ? Any other good options ?

OK. I am continuing to troubleshoot stator and here is what I have found.
Each pair of blue/red wires has a tap to the ground diving winding into two unequal(!!!) parts with resistance 6 Kohm approximately and 200 ohm respectively. I heard from somebody that higher resistance part is working on lower RPM and lower resistance on higher RPM, providing relatively comparable voltage on the whole range of RPMs.
Wondering - is that really a case ? does somebody has a decent description of this? Appreciate your help

The high/low speed windings use different size/turns of wire to create proper output. Just buy a stator and continue restore. Make sure you get correct thickness.
