Okay, this is going to be the bomb. Justin is very fast in responding.
Here is an excerpt from my correspondence with Justin (below), he gave me his permission to repost:
"If you like, I am happy to give you some answers to the questions being posed in your thread.
1) The installation manual for the Yamaha system is not online yet. The one being referenced is for our traditional “throttle motor” (i.e. mechanical cable) based system.
2) The motors in the preview video are indeed being sync’d. The starboard engine analog tach is off by 100+ RPM, which is why it reads higher than the port engine. If you listen to the sound of the engines, you can tell they are synchronized. Note that the synchronization only starts when the speed control takes over (i.e. not in the initial ramp up to speed).
3) PP
for Yamaha boats does not have the ability to bring in the RPM, to my knowledge. They removed that from their Yamaha offering years ago. This eliminates the tach on the display, RPM-mode, engine synchronization, etc. If someone can show otherwise, I will gladly have our website updated. They also have never had air temperature on any of their systems. Water temp can be brought if one buys/installs the paddlewheel, as our website indicates.
4) “No wake mode” is not affected by our system.
5) No splicing is required on the engine side – it plugs into the APS and CPS (cam position sensor). The power is all taken from the helm, which needs 5 wires tapped (see attached schematic diagram).
I hope this helps!
