The WaveBlaster is a personal watercraft (PWC) made by Yamaha Motor Corporation. Part of their WaveRunner line of watercraft, the Yamaha WaveBlaster 700 (Marine Jet 700TZ) made its debut in 1993. As a one person personal water craft with a motorcycle-like ride that let riders enjoy sharply banked turns, combined with its powerful engine and flat-bottomed hull, this is a model that still has many devoted fans today.

This ski came from the factory as a stripped down no frills machine that puts out all performance and no compromise. It does not have a tachometer, speedometer, GPS, rear view mirrors, cup holder, ice box, luggage compartment or a reverse mechanism that are typical of larger multi person skis.

The WaveBlaster has been described by many as "the closest thing to riding a motorcycle on the water".
