Trans Slipping?

Over the weekend I was pulling a wakeboarder out of the water and for a brief moment the RPM's shot up from 4 to 5k and there was a bad vibration, only lasted half a second. To me it definitely felt like the trans slipped. I had full factory ballast and 10 adults in the boat, so obviously a pretty heavy load on the trans. I checked the fluid and it still looked full on the stick. Any thoughts?

Boat is a 2012 x-15 with the 5.7 Ilmor, around 500 hours on the clock.
Thanks

Is the trans fluid discolored or smell burnt at all? If there is no evidence of failure I would say you had the boat overweight. Looks like it's rated at about 2300lbs. Subtract 900 lbs of ballast and that leaves 1,400 lbs for people and gear. Running overweight and trying to pull someone up the prop probably cavitated.

I've had boats 3-4k over the "capacity" plate and never experienced that.

Direct drive I have had them cavitate, it never recovered on its own though. Of course trash is the lake can do the same thing until that plastic diaper shreds.

negative pressure cause by environment around prop when it spins.. water boils around prop spins thru air.. look at your prop for irregular spots.

What about the transmission filter on these units. Will they cause fluid starvation if they are plugged?

Got it a lot on the X10, JD. Usually while tubing and trying to accelerate out of a corner.
