Question - do all the gauges  still work? Amazing if so.  

Easy fix if they don't though. Resolder the MDC, cleans earths and if that fails delete the MDC and fit a new TRD gauge kit. Takes less time than the resolder and earths.

Worn spark plugs or other loose/worn ignition components are the most common cause of misfires, but they are not the only possible cause.  Improper fuel pressure, faulty fuel injectors, improperly adjusted cam angle, excessive vibration or damaged prop/running gear are just a few of the other possible causes.

Curious to see what the intent of the fire tablet w/ android is?

I've tried with the workarounds on another thread via hotspot for spotify and navionics, but both failed to download, i will try again another time.

I'm curious what natively works that you all or using while on the lake? I would assume amazon music works, but i'll just keep using bluetooth probably

anything worthwhile?

The Controller Area Network (CAN) sends data through a pair of twisted wires from the engine ECM to the Viper dash controller and connects all of the associated modules in the boat.  A loose, damaged, or corroded connection on the CAN, or a faulty module could prevent data from being transmitted.  On 2014 and earlier Malibu boats, the ECM and CAN are powered by the switched ignition circuit which is energized when the dash power button is turned on and the start code is entered (or the emergency keyswitch is turned to the run position).

The boat wiring harness has a 16 pin rectangular Delphi connector at the engine harness and at the dash instrument harness.  Pin K red wires and Pin L black wires are for the CAN Hi and CAN Lo signals.  If a bad CAN connection is repaired or a faulty module is disconnected, then the CAN will work normally again after the ignition power is turned off and back on again (which also requires the start code to be entered or keyswitch turned to the run position again).

The modules connected to the CAN are: engine ECM, depth transducer, speedo paddlewheel, surf gate controller, GPS sensor, diacom diagnostic connector, Viper module, primary power module, secondary power module, rear MUX switch, mobile device gateway, radio module. 

I have fixed more than one CAN issue just by disconnecting the Rockford radio interface module or Mobile Device Gateway module, so I always try those first.  They are located on the amp board in the observer storage. 

The emergency key switch is wired to the engine harness through the 16 pin Delphi connector pin S yellow/red wire and it does not rely on the CAN to send a start/crank request from the Viper to the engine ECM.  If there was a CAN issue and a no-crank using the keyswitch, I would suspect a problem with the engine harness connector, or an issue with the neutral safety in the ZF shift controller (or one of the connections to it).
