hello. i am a total newbie, so please go easy on me!! i just bought my first boat. the engine is a 89 black max 150. it runs great. however the beep wont stop. it is a steady beep, i think it means overheating? ran it all weekend and didn't blow it up. the guy i bought it from warned me of this problem. when i wiggle the key it will stop beeping for a short time. so my question is, what is that box that could be need replacing? thanks for any input
