Help with 1995 Mercury 40hp 4cyl 2 Stroke

[tylerheath09]

So I recently picked up this motor for veryyyy cheap. I know nothing about boat motors and figured this would be a good starter outboard to learn on. Well long story short I have a wiring harness for it but once I have connected it when I turn the key all it does is a constant beep and won't turn over. I have made sure that the oil level is full, I have also disconnected the engine overheat sensor to see if that could be the issue. Still nothing. Also I have included a picture can anyone tell me what this red wire connects too? I am a beginner and at a loss!

Serial #?

06136906

 

[jimmbo]

Is the Serial # 0G136906?

06136906 is for a 4 cylinder Mercruiser

I feel like an idiot. You are correct it is 0G136906. Eyes aren’t as good as they used to be

 

[jimmbo]

Don't feel bad, we all misread things.

Update, The motor will turn over but I still have the constant beep. I’ve bypassed the over heat sensor, any idea what it could be causing the constant beep?

 

[jimmbo]

Is there an oil level sensor?

 

[tylerheath09]

Yes but I have bypassed it to rule that out.

When you say 'Bypassed', did you ground it or just disconnected it?
