I have a 1988 70 HP Evinrude 3 cyc 2 stroke outboard. It came off a boat my stepdad bought and he junked the gauges. Bolted it to the transom, hooked up the control box and fuel tank, with a new fuel line/primer bulb. Had it running on the muffs for a little bit. The control box has a small button I have to push in before starting the engine. Also it has a push in choke on the key. The first time I ran it I would just have to push in the little button, start it up then let it go- and it would run fine. Today it will only run as long as the button stays pushed in. What's going on? Also I took off the VRO and just premix it. I plugged up the oil fitting with tape. Are there additonal wires I have to disconnect also? Its pumping a good stream of water while running. After running for a minute a buzzer goes off in the control box. I shut it down right away. I feel the engine and its not overheating? I have the Clymes manual an it doesn't have anything about the control box in it.
Man, I haven't got a clue. Any help would be a lifesaver. Thanks- I try to post a pic. Oh, and there's a wire coming off the box thats cut. Whats it for? There's also a tan wire on the motor that goes to another tan wire , should i connect them?
