Horn

[Pontoon89]

Horn never goes off. As soon as key is turned on the horn blows. It is a 1990 40HP Evinrude. It cannot be overheated as the motor has not even been started. The motor runs fine but the horn will not turn off.<br />If it is the horn, is that a difficult thing to change? Could it be something else? Help.

Re: Horn

Try disconnecting the sending unit then try the key again. If the horn doesn't blow the sending unit is bad. If it does blow there is a short somewhere. Do not run the motor with sending unit disconnected. Replace if needed about $12<br /><br />Smitty

Re: Horn

Smitty,<br />I am not familiar with motor. Where and what is a "sending Unit"? Where is it located?<br />Thanks for your help.

Re: Horn

My Johnson and Evinrude both have a brown wire going into the head. Back by the spark plugs toward the top og the head. Yours should be the same.<br />Smitty
