Author Topic:   2001 Optimax 150 Smartcraft compatibility with Navman 8120 or Northstar M121

adriano posted 08-13-2008 01:30 AM ET (US)
I have twin 2001 Mercury OptiMax 150-HP motors with Smartcraft serial no 0T390000 and I was wondering if the ECU/PCM on these particular engines are compatible with the Twin Engines Gateway used to interface Smartcraft with the Navman /Northstar units. Can anybody shed some light for me on this as I have emailed Northstar but heard nothing back! Is there anyone out there currently using a 8480/M84 or 8120/M121 with 2001 150 Optis and able to monitor the Engines data? Thank you.

I looked for an answer to your question in the NorthStar literature:

but I did not see any annotation of which model year motors were applicable.

It might be an expensive call from Australia.

Check out the PDF. Both systems are 0183. Should be good to go.

That's better...

The NAVMAN 8120 unit only has a NMEA-0183 interface. It does not have any SmartCraft interface. It depends on the SmartCraft Gateway to perform the translation and electrical interface. There isn't any information about SmartCraft model year variations in the manual for the Navman 8120.

Thanks to everyone who tried to answer my question. I have bought a twin engine Gateway and will try installing. Once I know I will post my findings.

Hi again, I have installed my new NAVMAN 8120 with the twin engine gateway and this is where I am:
First of all I was able to use my original blue cables with terminators at both ends by removing the resistor between cables white and blue at the opposite end to the engines. I have then plugged these two in a four-way Smartcraft Junction Box and the other two ends are connected one to the Gateway and the other to a Weather Cap, as per the Smartcraft Gateway instructions. I have then setup the two engines with the DDT one to STB and one to PRT.
I can now correctly monitor the STB engine but unfortunately I only get RPM on the PORT one and nothing else.
Any idea why?
Adri
