Re: 2003 Mercury 115 , warning alarm horn
bfryer, you may want to read the posts on this forum with my problems under "no alarm at start" and "Quicksilver controls" posted by lgreen8303. I found a bad ground connection. You should have an alarm module and horn, I believe the module should be located near the oil injection system to monitor the level of oil. The horn for my module was located in the Quicksilver Commander Control module. To test is fairly easy, turn the key to on and ground the temperature sending unit on the motor, a constant alarm should output if it similar to mine. Hope this helps, lgreen8303
