I'm thinking of purchasing a 88 evinrude 140 for $800. The previous owner got it with a boat and just ripped it off. Supposedly it was running before it came off the boat. Currently I have it hooked up to a battery and the controls are plugged in. I go to turn the key and nothing. I tested the voltage of the plug coming out of the engine (that plugs into the controls) and there is no voltage. I've tried using a jumper to give power straight to the starter and it spins. Is there a solenoid or something bad in it?
