The Malibu XTi can be a tricky boat to weight for wakesurfing based on the amount of room we have to work with. We have had many customers that actually produce great wakes behind the direct drive Malibu's so it is possible. The most common setups are to either buy the Fly High V-Drive Sac Set or the Fly High Fat Sac and the Fly High Tube Sac. The sac placement is further explained below. Unfortunately, the XTi does not allow the sacs to be hidden.
Option 1: Fly High V Drive Bag Set - One on the side of the motor compartment and the other rear seat. This will give you around 800lbs. of ballast on the surf side but it will distribute the weight evenly.
Option 2: Fly High Tube Sac - The best placement is along the side of the motor compartment with a Fly High Fat Sac on the rear seat. You can use the tube sac to support the extra length and this configuration will give you the standard weight distribution for surfing with the majority of weight in the stern of the boat.
Option 1: Fly High V Drive Bag Set - One on the rear/side seat and the other in the middle leg room on the floor. Because Malibu has a left hand prop rotation coupled with the extra weight of the driver the starboard side surf wake is usually cleaner with less ballast.
Option 2: Fly High Tube Sac - Placed in the walk way next to the driver for added mid ship weight with a Fly High Fat Sac on the rear/side seat. This option will produce a tall and long wake for surfing.
