'24 P23 Port NSS surf actuator fault

[Jenglish]

Meant to post only once. My computer is glitching out this morning...

Hey all — hoping someone's dealt with this. My port NSS surf actuator keeps throwing a comm fault. It's been in the shop 6 times for warranty work overall, and this specific actuator has now been replaced three times (once in Aug 2024, then twice more in a single visit this summer after the first replacement still faulted) — and it's still not resolved.

One theory I have: could the thruster draw be causing a voltage sag that's damaging or faulting the actuator over time, rather than the actuator itself being defective? If the thruster and the actuator share a battery or power circuit, repeated high-current draws from the thruster could be stressing that circuit every time it's used.

A few questions for the group:

1. Has anyone had a port NSS actuator fail repeatedly like this? Trying to figure out if it's a bad batch of actuators, a wiring/connector issue upstream that keeps killing replacements, or something else entirely.

2. Does the factory thruster share a battery/circuit with the surf actuator system, or are they isolated from each other? If your dealer traced a repeat actuator failure to its root cause, what was it? (Bad ground, chafed harness, voltage sag, water intrusion, etc.)

3. Any luck getting Nautique corporate involved when a dealer can't get to the bottom of a repeat failure like this? My dealer has been responsive, but three actuators in under two years on the same port surf unit (which never resolved the issue) feels like there's an underlying cause nobody's found yet.

Any insight from other G23/Paragon owners would help a lot. Thanks in advance.

You should definitely contact Nautique corporate. They can be very helpful.

It's a long shot that this has any relationship to the thruster.

For the actuators that have been replaced. How was it confirmed that the actuator was actually bad? I suspect the problem is upstream of the actuator itself and the multiple replacements has more to do with them not being able to isolate the actual problem than the actuators themselves being bad.

Thanks for the input. I’ve actually tried getting in touch with Nautique corporate on this — the specific tech support contact I need to speak with has been out of office, but he’s supposed to be back next week, so I’m hoping to get more traction then.

On the “how was it confirmed the actuator was bad” question — that’s a really fair point, and honestly I’m not sure the dealer fully isolated it each time vs. just swapping the part. I’ll push them on that when I follow up too.
