Hey Crew and Wetsounds specialist.  

I am an advanced stereo guy for a little background.  Home audio and all my rigs have custom setups.  

2024 A225 7hrs on the boat  Sound pack 3. 4 rev 10s.

The 4 rear cabin speakers randomly stop working. All of the zones are set to equal volumes. The two fronts continue to work as well as towers and sub.  A power cycle of the new Wetsounds head unit does not fix it.  A power cycle of the boat did not seem to fix it.  After power cycling the batteries they sometimes start working.  It goes in for the 10hr break in maintenance but an intermittent problem is troubling. I checked connections on all the amps.  


Any guidance?
What is the best description to tell the dealer. I do not want to lose downtime for an amp issue.

Look for excessive moisture, corrosion, or pin/wire damage, wear, or bad crimps at the connectors.  The Delphi connector plastic purple pin retainer often needs to be removed to properly inspect the female pin sockets.  Careful, they are very easy to break as they get older.  Look for wear on the center contact on the female pins.  If they are worn and bent down, they can be bent back up as a temporary repair.  Replacement of any worn pins is best (if needed).

Here is an example of one bad female pin sockets on a different kind of connector.

And this is after a temporary repair.

+1 vote for M6 in any of the boats you are looking at. I came from the 6.2L Raptor motor in an older 23 LSV and it felt pretty equivalent to the M5 on power, but after having a M6 in the 2024 23 LSV, I wouldn't go back. It's hard to beat the extra power as these boats just keep getting deeper and heavier. As another reference point, my local dealer generally orders all stock boats 23' and bigger (plus M220) with the M6 as it handles people and ballast (especially PnP) much better than the M5. And keep in mind we're only 1,200' elevation.

Speaking of weight, there is now only a 200lbs dry weight difference between the redesigned 23 LSV and 23 MXZ. I agree that weight is likely in the front but have found very little difference in surf wake between the two so far. I think the bigger difference is space and the price tag, which I could not justify. The wake on the new 23 LSV is pretty awesome, certainly better than models years before and rivaling the much deeper M220.

I believe the more "chair-like" rear lounge seats are only available on the new M242, 26 LSV, and (maybe) 25 LSV. I can see the allure in full seat backs, but we often have multiple people back there laying or sitting so wouldn't work real well for our lounging.

Best of luck on your search, fun times!

Nice to hear.  Agree on the m6 but there was a leftover 23 with m5 at a price hard to ignore,but still to expensive to have regrets 

The 16-pin engine to boat harness connector is on the port side of the ECM bracket near the fuse/breaker box that is mounted to the top of the transmission.

The neutral safety switch engine harness to ZF control harness connector has yellow/black and black wires and it is located near the transmission shift solenoids.  Jumping the A and B pins on the NSS connector provides the ground to the starter relay so the relay can be energize when the ECM sends voltage to the relay during a start request.

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).

CSCleaver, thank you so much. 

Is the ECM located at the back of the boat on the transom?  Once I locate the connector do you think I should just clean the pins or what should be looking to do exactly?

What is the best way to bypass the neutral safety switch to test if that is the problem?  I'm sure you know but there are two connections to the shifter and it's not logical if what is what.
