Won't go faster than 13 mph...

We have a 2009 X-30, and recently had a strange occurrence where the boat would not go past 13 mph. We had no alerts or warnings, so it does not seem to be in "limp" mode, at least not for any real reason.

Here's the scenario. We'd had a full morning of fun, and had just finished up some surfing sessions where we had the starboard side hard tank and the piggyback bag in that side locker full (750 lb bag). The wave was great, and we did our normal technique of setting the Perfect Pass to 13 mph to get up to speed and form the wave, then backing down to 10.4 mph, which seems to be the perfect speed for us to surf at (wave stays mushy unless we go a bit faster first, then back down).

Next up was a wakeboarder, so we drained the tanks and started pulling him around 20 mph. All was well for a few minutes, when suddenly the boat slowed to 13.0 - 13.5 mph. No matter what we did, we could not get it to go faster. Perfect Pass off or on, it did not matter. Note that in neutral, I could rev the engine up into the 4,000-5,000 RPM range, so there did not seem to be any RPM limitation going on.

So, we headed back to the dock and had to call it a weekend. At one point, with Perfect Pass on set at 34, it did slowly get up to about 30 mph, but it was still not right so I backed it down to a slower speed to head back, as we did not want to get stranded.

I do have an appointment to get it looked at, but I was wondering if anyone had any idea what might be going on. I've heard various theories from a fuel pump issue, to Perfect Pass malfunctioning, to possibly the effect of driving it with that starboard ballast full...

Any thoughts?

Disable the perfect pass and try. Could be perfect pass not disengaging.

We had something similar last spring where our boat would only run 'correctly' at slower speeds and we could get it up to higher speeds at times but it didn't feel right - like you stated. It turned out the fuel filter was clogged and needed to be changed.

Have u tried a hard reset on the perfect pass or completely unplugging and disabling it from the master module?

Their modules go bad from time to time.

I'm not sure how to totally disable the PP. It is off, and I did try turning off the batteries to see if it needed to reboot, but it is still stuck at 13 mph...

I will get the fuel filter checked out..., it would be great if it was something as simple as that!
