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 …

Thanks for the response. I understood anything that is in any kind of vehicle should be stranded wire. I also understand that solid "stranded" wire will have more capacity than copper cladded aluminum wire. I am planning on using the OMC Red Plug for my control wires. My question is about getting the power from the battery to the engine (28 HP Outboard). I'm planning on using Jumper Cable or Welding Cable wires. the length will be less than 5' (Probably less than 3'). I do not know much about the starter motor (except its over 60 years old).
So, should I use 6 Gauge (stated good for constant 200 amps) or move down to 8 or 10 Gauge?
Again, thanks for your almost immediate response,
Chris
