Pulled a slalom skier for maybe 4-6 runs last Saturday at 34 mph and no issues. Pulled a new skier today who was getting up on a HO Hovercraft and wiping out 3 straight times before getting up. Felt like the engine bogged down slightly during the hole shot, and then was fine. When skier wiped out, I would pull back the throttle immediately to neutral and the engine light came on and the engine had killed/stopped. Would start it back up fine. This happened 3 straight times. Then got her up on two skis and everything was seemingly fine. Then I took out without a skier and seemed normal. Oil pressure was 20 and would get up past 40 once it was planed out and moving. Engine temp was around 140 and dropped once planed out and moving. Thoughts? Maint. / Tech.

I am hoping someone with experience can help. I am based in Singapore, and unfortunately there are very few PCM technicians here.

The boat has developed a no-crank condition and I have spent several weeks troubleshooting it. I would really appreciate another set of experienced eyes

Boat Information

• 2014 Nautique G21
• PCM 6.0L (ZR450)
• Engine Serial Number: 740186

Original Symptoms

• Engine does not crank from the ignition key.
• LINC powers up normally.
• Fuel pump primes for approximately 2–3 seconds when the original boat key is turned to ON.
• Various relays/solenoids can be heard clicking during key ON.
• LINC does not display any engine data (oil pressure, engine temperature, battery voltage all read 0).
• DIACOM cannot establish communication with the ECM.

I have a video of the above in youtube

https://youtube.com/shorts/lJx9S_HqL...cWb_BoCHUgQxsX



Checks Already Performed

Starting System

• Batteries tested and confirmed good.
• Battery selector switch tested in Position 1, Position 2 and BOTH.
• Starter motor cranks normally when the starter solenoid is energized directly.
• Starter relay replaced with a new relay.
• Same symptoms remain.

​Any advice from members familiar with PCM engines or would be greatly appreciated.​

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.]]> Maint. / Tech.

on my 2018 SN 200 (H6 motor) I have a pulley or accessory squeaking at idle after the boat is warmed up. 620 hours, regular maintenance performed, I replaced the serpentine belt already and that didn’t fix it. It sounds like it’s coming from the alternator but I can’t be sure?

any ideas? I see in the manual to check the alignment of the pulleys, how do you that?

thanks,
