The best way I can describe a FX1 is that it’s like a 550 but on steroids.
Just for fun. Write short crappy reviews of jetskis you've owned or rode.

100% without question I have no doubt Krash tried as hard as they could to become an OEM in an industry left for dead, where kawi, yami, and scott watkins no longer cares. But without the ef you money to fall back on you get one shot and it did not work. Meanwhile yamaha can get money from their freakin Piano department if needed, and they still screwed up the 4 stroke superjet. too big and heavy to play, yet still 10mph slower than kawis offering of patio furniture.
Ill never understand the FX1. You have made the superjet for years at this point, everyone likes it. You want to copy a 550 and decide you're going to make some one off extremely crappy pump for it, but everything else is a superjet with a 550 style bottom deck.

Be a good podcast to hear the how they came up with the superjet, jammer, and fx1 and why they did what they did.
I would geek out to hear someone who worked for yamaha during the golden years tell stories
It was designed in 1991 when the 550 was king. Then it got held back to push the blaster out first. When the FX! arrived in 1993, 550s were a thing of the past. The 550 bubble popped for everyone. Now they are being raced again, just without (new) aftermarket support.

Like Quinc said. It's a hard meh at best unless you get one from Steve Bach and he fixes everything before you get it. Steve is legit though. Great guy.
The pump still doesnt make sense. Yamaha made the 6m6 a motor that cannot die, made it bigger and better, nailed the pump first try then make a 550 with some random 140mm pump and the only color is purple. Drugs?

Actually it's worse than that, the pump size is 122 mm , in comparison a Waverunner 500 has a 133 MM jet pump , I believe the Jet n cat and Jet n spray used up most of the 6m6 engines and 500 -650LX jet pumps, some if those boats came with 133 pumps and later models used the 144 pumps, the ones with 133 pumps were slow a$$ turds. A lot of Boston whales also came with Yamaha engines and pump as did the UFO Saucer ski.

Wavejammer 500 pump was mixed flow like a 550. Tapered impeller & housing. Fx1 122mm pump is axial flow.
Put me down as also in favor of a spec 300 racing class.

I never owned one,. I just remember someone saying they had parts left over, so they made the FX1

The little 122mm pump actually works pretty good on a bone stock ski, put anything with some power in the ski and it lacks badly, the FX1 with the 144 conversion is a really nice setup.

A little mismatched, Yamaha used an 8000rpm pump behind a 6000rpm engine. When you add impeller pitch to soak up the torque it cavitates horribly at low speeds.

The fx1 was advertised as the fastest sand up in production. I think it was 51 or 52 mph
