Mercury Bigfoot Oil / Temp Alarm

[kazeej]

I have a 1995 Mercury 60hp 2 stroke. 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?).

Do all motors have this alarm?

How do I determine if the alarms are on the motor?

If they're not there, can they be installed?

Thanks for any advice...

Jack

Follow no. 31 wire to a junction and ground the tan w/blue stripe wire...the alarm should sound. If not, verify the alarm is under the dash...it should have 12 volts on one side and the tan w/blue stripe wire connected to the other.

I'll do that after work today. Thanks for the info.

Definately need it working correct if your running the motor put a mark on the oil tank so you can monitor it is getting oil. Otherwise put some oil in your fuel 50:1 until you can confirm the oil pump is working correct. It dont take long to destroy the engine running without oil.

It does use oil. I top up the tank before going out each time. Is there a sensor on the oil tank that I can check, too?

Thanks!

There should be a switch on the bottom tied to the alarm. If you have a dash mounted ignition switch the boat builder may not have installed the alarm module that comes w/a side mount shifter ignition switch which sends a test pulse to the alarm...a single beep when you turn the key on. Mine did not so I installed a momentary test pushbotton switch to test the alarm. Let me know if you want to install one and I'll tell you how simple it is to do.
