Hi Tom
Thanks for the quick reply.
Not sure that is the problem.
With only one engine on at a time, there is still no valid PGN.
I will try disconnecting the engine with the invalid speed signal from the Yamaha backbone, and disconnect the gauges in case they are doing some processing or setting up of the Yamaha engine.
I don't have any idea how the NMEA is implemented on the Yamaha engines and if they do not adhere to the specification in the format of engine parameters the gauge may well do some processing and setup with instancing.
I might poke around a bit under the engine cover and see if there is something I can spot.

I vaguely remember the speed arrangement on these engines is an add on accessory. I will try and find the documentation that came with the engine.

I won't see the Yamaha guy for a while and I am not sure he would know anyway.
cheers
Bernie
