Assuming the Cobra is labelled like this ...
The Cobra Yellow goes to Raymarine Blue/White
The Cobra Green goes to Raymarine Blue/Green

AIS will send GPS too, so no need to have the Cobra connected.

Receive only .... the diagram is confusing until you look at the labelling on the Raymarine wires

You could help yourself and others if you actually posted some information, such as a link to the Cobra manual, as i requested earlier. If you can't be bothered to do that, why expect everyone else to look up your manuals ?
Have you checked the baud rates on the plotter ? If so, what are they ?

My AIS doesn't ... it's in a Standard Horizon VHF which gets it's GPS info from the plotter, which has a smart GPS attached - a bit like Cherods setup. It has 2 NMEA functions DSC and AIS ....
... but then my AIS is receive only.

Would possibly help if Cherod posted the make/model of AIS he plans to fit. If he fits one that does send GPS, having the Cobra connected could cause an issue, if not, he'll have to avoid using port 2 now. Your earlier instruction are spot on.

Could connecting to wrong nmea port blow a fuse ?

I'd follow the advice to connect to port 3 for now. If the AIS you fit also sends GPS, you can either disable that with the AIS software (most allow that) or disconnect/disable the Cobra GPS.

Paul, out of curiosity (not using N0183 anymore, I'm fully N2K) what's the problem in having two devices sending gps data? I thought in N2K land and larger boats it was normal practice to have a second mushroom on the bus, just in case the first one failed...

I think NMEA2000 multi-function devices allow for device selection so you can select a specific source for a piece of data where there are multiple sources of the same data. Each sender should have a unique number (set by SetDeviceInformation if available) and a model serial code ... e.g. if you have two water tanks that have the same NMEA2000 level sensors .... I have not tried it with GPS though as there are multiple sentences involved.
NMEA0183 does not have this capability AFAIK.

A couple of potential issues, sometimes having 2 GPS connected confuses the plotter. The other issue can be data loops. Problems will depend on all of the connected devices and how they deal with the data, whether they re-transmit it etc, but it's something to be aware of. Fixes vary too, sometimes a device can be prevented from re-transmitting particular data, sometimes a device can be prevented from sending particular data (AIS can usually be prevented from sending GPS, for instance). Sometimes you just have to disconnect a device.
N2K seems to be much more tolerant of multiple data sources, devices tend to be more configurable.

thank you guys, a second gps mushroom is way down the to-do list.
