Customer Question
I have a 4.3L MPI...
I have a 4.3L MPI Mercruiser. I have a Northstar 557 Chartplotter with a smartcraft gateway interfacing to the motor all is good. I can see all the usual oil press temp hours etc.
I have added a steering angle sensor which also works fine. I have recently added a Mercury Smartcraft in hull depth transponder (manufactured for Mercury by Airmac).
As per instructions I have plugged this into a connection near the ECM labelled Diagnostics/ Depth. The system does not seem to be able to see the depth transponder at all.
Is there a setting in the Ecm which needs to be set to enable the depth function.
The chartplotter can display depth supplied via the navbus.

Hello,

Which gauge(s) are you using?

SmartCraft version? Vessel View? Gateway Monitor?

If you have a Gateway Monitor, what level is it? If you are not sure, what is its part number?

The Gauge / Monitor is what processes the signal from the transducer, not the engines ECM.

You might have to scroll through your gauges setup functions to activate the transducer / depth feature.

I am not using smartcraft gauges. I am using a Northstar 557 Chartplotter with a Smartcraft gateway.
Marine Mechanic: Kenny, Marine Mechanic replied 12 years ago

OK,

There a few different SmartCraft gateways.

Exactly which Gateway are you using?

Are you still out of the water or have you tried this in the water?
