Try this .....
Reset the Chart Plotter ....
MENU -> System Setup -> Settings Reset
Now check your E140w is set up as data master.
MENU -> System Setup -> System Integration -> Data Master .... set to ON
Select GPS Data Source.
MENU -> System Setup -> System Integration -> Preferred GPS Source ..... Set to NMEA0183
Select Baud Rate for the port you have connected the Cobra to.
MENU -> System Setup -> System Integration -> NMEA Port Setting ..... GPS will normally be 4800 or 9600 ... try both if available.
Ports are as follows depending which wires you have connected it to.
Port One - the Raymarine Solid White and Solid Green wires
Port Two - the Raymarine Orange/White and Orange/Green wires
Port Three - the Raymarine Blue/White and Blue/Green wires
... after that I'm stumped
I don't know if the Plotter is new to you or brand new .... if it is second hand, then the previous owner may have set up the NMEA ports to receive Navtex data, AIS data ... or engine data .... so a reset should clear all these settings out.
EDIT: As long as the GPS is powered and can see satellites then it should transmit its data (even if the wires aren't connected) so leave it powered up and you won't have to wait for a GPS fix - as soon as the data starts coming through you'll see it on the GPS Status page of the plotter.

I think i did do a reset. ,
will do , does it matter if i am on radar or chart or what ? Thank you gor your help , my head is fried with this stuff

It doesn't matter what you are displaying on the Plotter .... best just to have the GPS Status info visible.
I've read through the CM 300-005 Cobra Positioning System manual (if it could be called a manual) and as you seem to have the yellow/green wire variant I am certain the wiring to the Raymarine NMEA ports is correct as detailed above. I also assume you are using the supplied Cobra Universal GPS Cable (the one with the yellow and green wires).
I think I know what might have blown your fuse .... the headphone-like connector has 4 contacts as it can be used to supply power to the GPS from Cobra radios when used with the Cobra Radio GPS Cable - Now I don't know which is which, but one of those contacts on the headphone like jack is power so .....
If you have the other power leads connected and live (The Black/Red wires), then one of the contacts on the headphone-like plug is most probably live (but not used by the Cobra Universal GPS Cable) - touch it to ground and it will blow the fuse.
This is poor design IMO. You can check the continuity from the +12V connector to the four contacts on the headphone-like jack with a multimeter and if it shows continuity then this is almost certainly what blew your fuse.
My advice is mate the GPS cable and the Cobra Universal GPS Cable BEFORE you attach it to power, and heat-shrink it so it cannot part again - Then wire it in - I would advise against breaking this connector when the device is hard wired to power.

Of course, a brand new GPS could never be faulty and a 10 year old plotter couldn't either.
If you follow the installation steps, instead of keep swapping from port to port, you might get somewhere. If, at the end of a correct installation, it still won't work, something is faulty, simple.

mr baggywrinkle ,, thank you very much for all your patience and help today , ( and without the silly sly smarty comments , although i am sure you were tempted ) ) ,, unfortunatly after having followed all your suggestions i am still no further forward ,,, gave up on it and reverted to making up some switch gear so i dont have to dive down into the hull and disconnect from the battery everytime i changed some wiring ... think i may leave it now to the raymarine techy who will be around nxt week ( if i can wait that long ) . again , thank you very much

as i said, i trust the stuff , and of course it could be faulty , as with anything , but i would rather persevere with some possibles than submit to some improbables ,, however , thank you also for your help , and, and yes if it does not work then something is faulty . thank you for stating the obvious

done all that , using all standard / supplied cabling etc . was disconnecting from the battery before every change .

I told you how to do it in post #9. This is a simple job that should take five minutes to do, but you've ignored advice and flailed around switching wires and swapping ports like a drowning man. I, and others, tried to help but you come back with remarks like:
"supposed to be fully compatable "
"There is an orange and white , orange and green option but the tech ( raymarine service point ) said that is not the one " After i told you how to connect it.
"( not that i doubt any of you but )i still have the wires set ad the tech said "
"The Gps is brand new , the charplotter looks like it has never been out if the box , so i trust both ( so far ) "
You don't make it easy for anyone to help you, presumably why almost everyone else either bailed early, or didn't bother in the first place.

what a strange attitude you have , those points which you choose to cherry pick were very early on in the conversation , all of the suggestions which you and others gave i did try , even when some of them were contradictory , do you feel insulted that i did not just take your opinions over anyone elses ? ,, thank yo for your help tho you do have a very strange attitude .
only time will tell whither your assumption that the parts are faulty , whither the tech is wrong or even if you are right ,, i look forward to finding out .

i expect there are very few people who have indepth knowledge of this equipment so didnt bother puting their 2 p into the post , however the other person who does obviously have knowledge and time was very helpful without your need for snidy comments and strange attitude

I did not post an opinion, i told you how to connect GPS to port 2. I was fitting widescreen Raymarine plotters back in 2009/2010 when they first came out.
I made no assumption that the parts are faulty. I proposed that you follow the correct installation procedure, at the end of which, it would either work, or something must be faulty.
My "attitude" comes from the frustration of trying to help someone who won't listen and contradicts what he's been told.
Good luck with getting it working, be sure to post back what the result is.

as i said earlier , thank you for your help /input ,, i will certainly post a result . i hope it is a good one .

One last thing that might be worth trying:
Cobra Yellow to Raymarine Blue/White
Cobra Green leave disconnected
Raymarine Blue/Green to 12V negative
Don't be concerned that you'll be connecting an NMEA wire to a power wire, a lot of NMEA connections are made this way, it will not harm anything. Don't ever connect an NMEA wire to the 12v positive though.

Famous last words ... "it's brand new, it can't possibly be faulty".
If I had a quid for every time I've heard that from a client I'd be sailing a brand new Sirius 40DS instead of a 40 odd year old Westerly!
In reality, it's far more likely to be faulty when it's brand new than when it's several years old, just as likely, in fact, as when it's nearing the end of its useful life (it's called the "bathtub" effect because if you plot mean failures of a component or device over time, the curve looks just like a section through a bathtub)
This is fault finding 101 and the cause of much grief and angst to those who don't grasp the concept. Never assume a component or device is working just because. If you can't prove beyond doubt that, in this instance, the GPS *is* working, you have to work on the assumption that it *may* be faulty, Ditto the plotter
And if you've checked and double checked all the wiring and checked and double checked all the config settings and you're certain that it's correctly connected and setup, by far the most likely explanation for it not working is that something is faulty (either the GPS or the plotter and once again don't assume. The only way to know is to test one or the other using known working equipment to either feed a GPS signal to the plotter or read the output from the GPS. Any competent marine electronics tech should have the means to do that)

If you (or anyone nearby) has access to a laptop with a serial port (or laptop and a USB<->Serial cable) then you could connect that to the GPS nmea output wires, power up the GPS and then see what shows up in some serial terminal monitor software. An older laptop will likely have something called Hyperterm built in but on something new you might have to install Teraterm or something similar.
That might at least show if the GPS is outputting something readable.
Sorry if this has been asked already. I might have missed it.

Nope , nothing ( tho leaving it on for a while to see if if picks anything up ) but still saying “ no fix “ which i presume means gps . Cant think of anything else , have tried all the wire combinations that everyone ha suggested but still nothing , i feel that the wiring may all be working but something j am not doing on the screen is the prob , going to leave it to the tech who is the agent for both and see what he thinks / can come up with … ty all ?
