Max fat sac size in 2018 Malibu 21 VLX?


Recommended Posts

Hi all - our brand new VLX is on order and the dealer threw in 550 plug n play sacs for the rear of the boat; is this the biggest we can go on that boat and does it help to make a big difference in the wave size? 

Trying to blow away a wave I have surfed on a 2017 Mastercraft X10 with sacs.

We have 550's in the rear lockers as well. They make a big difference over stock. I ended up adding an 1100 Fat Sac in the bow later in the summer. I only filled that up halfway typically. It really helped out with bow rise and IMO, it made the wave much better.
