Just to bump this saga back up after two years.. I have now got a ST60 to test again. Amazingly, the transducer fits inside the removable housing of the DST 800 (I think) unit, so no need to retro fit transducer number 5....
I think I asked this before but cant find the response. The transducer has an offset angle, and the top of it has an arrow. Wouldnt the direction to fit depend on whether you install in on port or starboard.. one side of the hull it corrects the angle, and the other side it doubles it? Unless the sensor is floating inside the unit? I think 2 years ago someone told me I had this wrong, but I dont recall why!

Wouldn't you just rotate the transducer 180 degrees so that the sensor surface remains horizontal?

maybe got it wrong, but i think you place the transducer so that the arrow points towards the keel. That's irrespective of port or stbrd side.
JTB, the thing is that you cannot see where the sensor is firing, there's a glass/perpex whatever that is flush to the hull and the mechanism is slanted inside, hidden from our eyes (that's what I understand at least!)

Aha, sorry. I was thinking of the transducer I've got in the T40 which is removeable, it fits into a ring which is bonded to the hull, and then you rotate the transducer itself to find the correct downward-firing position. I fear my post may have served only to introduce confusion.

Ahh you are a star; that was it !! Nothing to do with pointing fore or aft. I think it is wrong in the Airmar instructions now I think about it, bcz I called the Eu headquarters (first name terms by now of course) and pointed it out to them.
I will give it a little twist.
Jimmy, how can you tell what is the right downward position? I think that is the purpose of the arrow (if Airmar gave the right instruction !)

NMEA2000 in practice does not appear to be all it was hyped up to be. It seems to work well with one manufacturers range of network devices, but fails to offer seemless inter connectivity between different vendors network equipment with out the need for kludgey converters and daft black box interfaces. The whole idea of N2k originally was a standard network including a standard connectivity system running a standard protocol and uniform interfaces that would facilitate plug and play, mix and match of devices. What hit the market didn't match up to this.
