200 Merc. Beeping 
			 
			 
			
		
		
		
			
			Hello, 
 
My engine all of a sudden starting doing this beeping thing. All of a sudden it will start this long continious beep, and the only way to make it stop is to put the throttle in neutral and just wait a minute or so.  
 
Someone mentioned that I may need to change the impella (did I spell that correctly).  
 
Is it an overheating warning? 
 
Thanks 
 
ps. the engine is a 94.
