Electric Starter Wire Cable Gauge Size (Pure Copper)

[BugleCoveTinBoat]

Does anyone know the proper gauge for pure copper (not copper clad Aluminum) for my Evinrude 28 HP Speed i Twin starter to battery cable?
I suspect it would be the same (starter, draw, cable gauge) for a 25, 28, 30, 35 or 40HP OMC twin cylinder outboard.
thanks in advance,
Chris

Solid cable or stranded? You should only use standed AWG cable. Starter load depends on the length run BOTH ways, to and fro, to determine the ampacity of the cable needed.

I know that OMC V6 OB starters have a peak amp draw of ~ 230 once energized and ~180 sustained. I have OEM Service Manuals at the house that likely list the recommended cable sizes, but I’m not home …
