Hey guys i have an old (late 70s) omc 400cc engine out of late 70s evinrude skimmer? i never got a chance to see the sled my buddy was scrapping it and pulled the motor knowing i had a use for it...My guess is the wiring wont be too big of a deal i can only see a couple, anyone have any info on wiring for this motor? or maybe can help me find some more info on it?

Yellow wires are for lights, the other two are the coil and kill.
Brown wire is ground.

thanks man...so if im using a key switch i will run the kill switch wiring through that instead of a kill switch? its going in a golf cart, it has a starter/generator i plan to use so my lights are already powered

Well, you can use the yellows run through a regulator to charge the battery if needed,

in place of the generator? thatd be a little simpler it sounds like all i would need is a voltage reg. correct? im pretty sure ill be able to easily put a pulley on this it has a small belt running to like a cooling fan i was just going to attach a pulley there and run it to my starter so itll still start with the key..if i run into trouble with room or mounting the pulley the yellow wires will put out 12v through regulator?

Do you mean add another pulley to run the starter/generator?
I think that you will find that it takes a lot of hp from the engine to run it.
If the engine has the the mounting hole and the flywheel has the ring gear on it, adding a starter will be fairly simple.
Otherwise, just use the pull start or have a way to disengage the unit after the engine is running. The lighting coils put out enough power to run some lights and charge a battery as well.

so i finally brought this motor in my garage, ive got a couple orange wires 2 green 2 brown and 1 yellow, and yes that is what i was planning was just adding another pully, im not so worried about the starter part of it, all i really need is to run a couple lights would love to get rid of battery

btw helps greatly appreciated man, i timed this pretty bad because i have a ton of work on my sled to do before snow and this is now in the way so i can use all the help i can get to avoid snags

I forgot to ask, (just assumed) is that a twin or single cylinder engine.

350D50 · 09-10-2009, 01:53 PM

Its a twin lol, says on it model no. 255 spec no. 161167

So i finally started messing around with this last night, i took the carb off and cleaned that, im not sure how long it had sat in a field before my buddy picked the sled up but i gave it a shot of gas in cylinders put in the plugs that came in it and it fired up second pull ran outta a bucket of gas i was pretty impressed.

You do realize that you have around the same horse power as a 1960 VW Beetle don't you. That's going to be one powerful cart.
