Make boat beep when key is turned.?

Question

Hey guys Im almost done fixing up my boat now and this time I want to replace the buzzer in the ignition switch. It goes off for second when turning the key or anytime the engine over-revs/low oil/overheats. It is activated whenever the alarm wire from the engine is grounded and is run off of 12v accessory power from the ignition switch. When it goes off it makes a god awful screech, so I would like to replace it with a more pleasent beep or chime or something. Can I find something at like west marine or radioshack or something to do this?

I should mention that it is an OMC ignition switch for a 1987 Evinrude. A link to the wiring diagram is here: http://continuouswave.com/whaler/reference/ignitionSwitch.html

Answer 1

It makes a godawful loud noise so you can hear it in a storm with the wind in your ears and nobody watching the motor. You can make it sound like a cell phone if you want to. But if you hear it ringing find out why.

If you want, just add a red light to the dash where you can't miss it. Wire it just like the buzzer.  

Answer 2

William has it right, You definitely want to have this annoying sound, You will deal with the problem.

I had a cruising friend that neglected his, lost oil pressure, and was stuck in the Bahamas until he could get a tow back to Florida.
