Frequently Asked Questions - Engine Alarm

Q: Why do I even need an Engine Alarm System? I watch my cockpit gauges when I am motoring.

A: All of us most likely do take a glance at our cockpit gauges occasionally but we do not watch them contiunously. That is what this alarm system does, watch oip pressure and engine temperature continuously. So if your raw water intake suddnly gets clogged or your pump impeller fails or you develope an oil leak, the alarm will sound and allow you to take corrective action before engine damage can occur.

Q: What makes this kit so special? It is just a standard Cole Hersee kit available at most marine stores.

A: You are quite right, it is based on a standard Cole Hersee kit. What does make it different is that it has been put together to include all of the hardware, fittings, connectors and instructions to facilitate installation on a late model Atomic 4 with an Indigo Thermostat Kit installed. There are other kits available but they do not allow you to have temperature sensor located in locations with good coolant flow.

Q: How come the kit does not include any wire? That seems kind of cheesy!

A: No two installations will be identical. Most everyone has there own preference as to where the Alarm Buzzer should be located. By cutting and fitting your own 14 or 16 gauge wire, you can make a nice neat configuration that best suits your installation.

Q: Can I install this kit on my early model A-4?

A: Yes. Since the early model head did not have a provision for a temperature sensor, you would need to install a tee in the re-circulation connection on the Indigo Thermostat Housing. You would then install the alarm temperature sensor in one connection on that newly installed tee.

Q: How hard is it to install this kit?

A: Typically the most difficult part ot this installation is removal of the existing temperature sensor in the head. If it has not been out recently, it can be very stubborn. It is recommended that you use a "6 point socket" on the sensor to unscrew it. The remainder of the installation is pretty straight-forward. You will need to have a crimping tool to attach the electrical terminals to the wires.
