NMEA 2000 Netwrok

does a 2003 yamaha f225 TXRB have a plug in to go on a name 2000 network to connect to a garmin?

No, it does not.

Hi, I know this is an old post. Hope you can still help.

I know early Yamaha 4 stroke outboards don't have the NMEA connection, but I would think the data would still be there.

Could you provide the ECU pin outs for the NMEA connection so I am able to wire up my own NMEA data point?

Thanks.

Regards,

Hi Vic - yes, the "data is there" - inside the ECM-
but the only way to access it, prior to "Command Link" / NMEA 2000,
is by connecting to a PC running the YDIS software.

the capability for "conversion"/"transmission" of data via NMEA 2000
was only programmed into ECMs in or about 2005

Ok, so all it needs is a reflash of the ECM and some wiring?

I have done similar mods to my car. Adding the Power train twisted pair bus to the diagnostic connector and have then reflashed the ECU/ECM with my laptop to later model software. All pretty easy stuff.

Do you have any links to download later Yamaha engine software or know of anyone doing these mods?

I can't offer any insights into flashing the ECM.

If I were determined to get the engine data,
I would buy a used >2005 ECM - and wiring harness - on eBay -
(and then - hopefully - sell mine for about the same price)
