Yamaha FX-1

The Yamaha FX-1 is a stand-up type personal watercraft (PWC) made by Yamaha Motor Corporation. Part of Yamaha's WaveRunner line of watercraft, it was introduced in 1994 and discontinued in 1995. It was built in very limited numbers and only around 1500 total were made.

It has the same 701cc 61x single carb engine as the 1994 SuperJet but has a lighter and narrower fiberglass hull (compared to the SMC hull on the SuperJet).

The FX-1 is similar in size to stand-up skis from the late 1980s and early 1990s and is a departure from the larger race skis that were being introduced at around the same time.
