'07 Nautique engine problem

[Thomas Wayne]

We have an annoying problem with an '07 Nautique 196 Limited, PCM 330 HP. At speeds under 30, engine cuts out randomly for a micro-second at a time. Not enough for skier to feel it, but very annoying to the boat crew. Problem occurs with or without the ZO turned on.

We've tried:

New cap, rotor, plugs, wires, "Heet" in the fuel, removing the anti-siphon device at top of fuel tank.

So far nothing has improved the issue even a tiny bit. I'm hoping someone out there is familiar with this problem and knows of a fix - other than jacking it up and driving a new Malibu/Mastercraft/etc. in underneath it...

Have you checked the grounds? Had this happen once on an MC where the ground on the block was just slightly loose and would cut the engine out at certain RPMS due to vibration. Just a thought.

I'm having the same problem with my '07 206. I haven't resolved it yet. I've tried new plugs, both fuel filters, gas treatments. Keep in touch as I try to solve problem, I'd like to know what you have done also.
