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.[1] 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). At 267 pounds, the FX-1 was marketed for its maneuverability.[2]

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.
