Shitzu Jetmax appeared in each part of the Grand Theft Auto games series, starting with GTA: Vice City and it has became a symbol of a on-water races in the GTA universe. As Jetmax was transferred from one part of the series to another it suffered completely no changes, except for a painting, which was different in each new GTA, also boat's manufacturer was changed in the fifth part from Italian Grotti (GTA 4) to already mentioned Japanese Shitzu. In GTA 5 Jetmax's painting looks rather softly, white colour prevails and there is a few dark-blue lines on the top of a boat.

Shitzu Jetmax is a completely made-up boat and it is hard to say if it actually has any prototypes, but there are some similarities between it and Fountain 38 Lightning, Formula Fastech 312.
