1954 25hp Choke solenoid

[wbeaton]

Things went so well with the two 7.5hp Evinrudes I rebuilt/repaired this year that I decided to complicate my life with a 1954 Evinrude 25 hp Electric.

I understand that the choke solenoids on these motors can be troublesome. Does anyone have any wisedom they can share regarding these? Are there any parts in it that I should replace when I rebuild the carburetor? I have a late 50's OMC shop manual, but I'd like some "real world" advice if there is any.

Thanks.

I'm just familiar with the later, reliable ones. The '54 though ought to be 6v. Perhaps the trouble comes from running one at 12v?

No trouble with them that I know of, except trying to run them on 12v. The newer 12v motors used similar chokes for a bunch of years with good success.

only prob I have seen is the tab you bolt the "hot" wire to breaks loose, I remove it and hook (solder) a wire to the wire that sticks out to attach to the tab.

Thanks a lot guys,

The resistor info is priceless. I was wondering how to run this motor on 12V.

Now I just have to get this stubborn flywheel off.
