Try Gary at Bristol Marine in Southern California. He has had parts for my Gray Marine 4-112 and rebuilt the carburetor for me a couple years ago and not only rebuilt but re-engineered the water pump to improve it. His phone number is 714-846-2039

I think that you'll have to look for a very long time to find a 6V positive ground generator.
A 12 negative ground conversion will end up costing much less too.
You'll find that the biggest challenge is the mechanical attachment to the engine, so that's what I would concenetrate on.
I converted my 12V generator to an alternator ( ex Honda Civic) and it has worked just fine.
The conversion 6V to 12V steps are common sense - the ignition coil, the starter solenoid ( but not the starter), the bilge pump ( and other motorized devices) and any lights - ( and battery of course) . You'll need to think about the fuses as well. Generally the wiring is OK since you'll be drivig about 1/2 of the current with 12V compared to the 6V system. Likewise, the switches should be OK too.

I found that using 12V on a 6V starter was no problem, in fact it was better, since the starter gave the engine a good fast kick, which helps with old engines.

You'll find a posting on the 6V and 12V stuff under the electrical topic.

It seems to me Positive ground in a boat that is used in salt water is a NO NO? It can eat out hull fittings, nails, you name it big time. Convert ASAP to Negative ground is my reccomendation
