I have a 1995 Mercury 60hp 2 stroke Bigfoot (that's a mouthful). It came on a boat I bought used. It runs fine, but I don't think it has a working oil/temp alarm. When I turn the key, there's no chirp (my other boat has the alarm and chirps, I'm assuming it's supposed to?). So I have two questions - How do I determine if the alarms are on the motor, and if they're not there, how do I add them?
