1. Engine will not start. Battery is full, key fob is at helm.

Nothing happens when the start button is pressed.

Error message: Engine lost comm. with Helm. Check EVC system. Gear auto set to neutral.

Gear select blinks red at neutral.

2. Was able to start engine after trying multiple things on one occasion and noticed no boost indicator on gauge, but engine has full power and speed.

Engine time 123 Hrs.

Prior to problems noted above, 100 hour service just completed at 120 hours.

Any help or ideas appreciated!
 
Sounds electrical. Loose cable to the evc?
Loose battery to starter cable?

Classic question. What happened / changed before the issue arose?
Perhaps the service tech knocked something and now it’s intermittent?
