Dank, it’s great to hear you got it dialed in, but too bad these boats aren’t delivered better setup! Can give us any more details on your trick of “covering up the vent holes” or moving the timers up the tube?
It’s not the timers it’s the water cutoff.
There are 4 screws on the panel in the rear locker. Two on top two on the bottom. Take those off, grab the plastic box on the line and push it up. You will want to raise it pretty far up.
Here is a picture from when I did it a couple weekends ago.
You will need to bleed the bags every time out. I had 1/4 of the bag as air each time. Unless you T into the vent line at the top and run another vent out of the top of the bag.

Water cut off - yes, agreed (below)
But timers were also set too short.
On the air venting, I'm puzzled as to why because don't they have those new self vent bags?! The new bags definitely have new style vents that weren't on the old bags, for sure. (Not taking about the air vent cap, but the others)...

2018 MAX - sold - 250 hours, absolute awesome boat.
The self vents on the stock fat sacs and WM bags since they use the same vents are not enough and frankly don’t vent worth much. Overflow vent on top is best IMO.

How much did you have to change these? What are they set to?
Are the 0-100 numbers on the screen for ballast fill just a function of the timers? And then the "red dot" is when the water cutoff sensor is seeing water?
I've switched the manual switches a bunch after the bag is full trying to see if it will purge out the side of the boat and it never has. Bag is full and bled of air.

I don't see how you can get the rear bags to purge unless you take off the cutoff sensor. The hose goes up and turns back down making a hump after the cutoff switch, I have been able to get the front bag to purge out the side but the cutoff switch is about level with the outlet port.
