Can some one tell me the procdure of trying to start a 1987-40hp yamaha with out controls? I know how to jump the solonoid but how do I connect it so it is getting fire to the plugs?

I believe these motors need to have a way to kill them, ground a wire through the key switch or kill switch.

just hit solenoid to turn over and start

I have no key switch, I do have the wiring harness but there is nothing connected to it. i bought this motor off craigs list for 100 bucks and i want to see if I can get it running.

Is it a pre mix or oil injected? you need to make sure it has oil needed and water for cooling.
Like I said just turning it over should start it, but you need to find a way to kill it before you start it up or you will be running around trying to figure it out while in a hurry.
