you will be fine using the 12v for the starter, just cant lay on it extensivly like any starter......
my '56 is 6v as well........i too manually pull the choke rather than frying the solinoid, no big issue, only ever needed it was for a cold start.......once you get your motor dialed in, the starter barely turns over by the time it fires up.........if you plan on using the choke, use a push button switch, that way it is only on when you want it on.........cheers

Quick update.
I redid all my wiring, installed a kill switch on the battery (to quiky address the melting harness experienced last year) and installed the 6V battery. Then... ignition switch and ... the starter would barely move No cranking whatsoever.
Went back to the 12V battery but for now, I set the choke manually.
Once the motor is fixed, I'll reuse the electric choke, and maybe add a small RED light or buzzer to remind me it is on

OMC didn't introduce 12 volt systems until 1957. Just get a 6 volt automotive starting battery and you will be in business with out having to change any other parts on your motor. If you are running your running lights off the starting battery you will need 6 volt bulbs.

The start will be fine on 12V as long as you don't crank the starter for extended periods. The 6V choke and starter solenoids won't like 12V for long. I normally replace the 6V choke and starter solenoids with 12V versions and call it good.

Hi all
As I was reviewing the wiring diagrams on this website, I noticed that for a 1955 OMC there are 2 options: 6V and 12V wiring diagrams. So checking my setup, I found a 12V battery and a 6V starter solenoid, which now probably explains why I got some wires melting last year.... Consider that I'm learning/debugging the setup from the previous owner.. which I enjoy.

From the Johnson service manual for my 25HP (Big Twin Evinrude), it should be a 6V configuration.
So my questions for you are:
1) Is there a way to check the rating of the starter itself: the label is Auto-Lite MAK 4033M -5J.
2) do you have a recommendation for the 6V battery itself?
