Slipping or cavitation? I hate that my first post is a Maintenance one....

[JDC02SANTE]

So I just experienced this same feeling last weekend while dragging the kids around on a tube in my '02 SAN 210 SE (GT40). I also felt it the first time during a turn. Lots of wind/chop that day as well. Backed it down as soon as I felt it, it went away. Felt it two more times over the next 20 minutes so I shut it down for the day/weekend. Got it sitting in a barn now, so all the info in this thread gives me a good start. I'm probably done for the year anyway as bow season is right around the corner and so is the cold weather. We'll see what I find. liquiddreams your situation turned out well.

I have had this happen enough times on my 2006 SANTE that I am confident it happens due to water, wind, and weight distribution in the boat.

Good luck. I ended up changing the transmission to a 80 series and have been happy with it. I did a step by step you can search up in case you go that direction (hope you don't have to though). My issue was the transmission cooler sprang a leak which allowed water in the system. Instead of rebuild I just upgraded to the 80 series since my main use is wakeboarding and surfing.
