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.<br />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? Can't get a URL for the pics. There's also a tan wire on the motor that goes to another tan wire , should i connect them?

The wire cut from the controlbox is one of 3 wires for a tach, originally they all came out of that connector. Just remove the connector the wire hangs from from the control box, as long as you dont have a tach. Which wires on the motor is the problem. The green and red grounded ones ?? You should never ground wires you dont know what are. Did you disconnect the VRO vires from the motors harness and the two wires comming from the VRO oil tank ?? Try to follow them from the oiltank to the motor.

Yeah the green and red one in the pic.<br />What are they for ? I think I disconnected the Vro off the motor. Is there an alarm for the oil pressure?

The butoon you have to hold is the safety switch. You need to get the safety switch/lanyard from a dealer and it snaps on that button.

I have the wiring diagram and I can't make head or tails of it. The only greean wire it shows is to the titlt motor but it all works fine up and down. Are the two wires ( green and red ) in the pic wired right? What is the thing its wired to?<br />Engine runs fine but an alarm comes on , I feel the engine but its not overheating?

Yeah, needed a lanyard, got one for $7.<br />Thanks, the motor runs great...<br />But after running for a little bit the VRO alarm goes of , 1/2 sec beep- 1/2 off, beep, etc.<br />The oil fitting is capped off and clamped. Vro harness disconnected. What now? Disable the horn
