https://pro-tec.us/pro-tec-open/17-yamaha-super-jet-open-intake-grate.html This is all you need.

"Take a peak at that intake grate. How’s it look?" That grate is way too aggressive. All you need with the 144mm pump mod is a open grate that runs flush with the bottom. Your ski will actually be faster and they'll be less stuff scooped up on beach landings. Your glass work is looking good!

Yamaha uses the green thermoset stuff that offers a little flex. As you know, it has to be chiseled or ground away. 5200 is a lot more flexible and is air cured. You can also remove that stuff with grinding/chiseling. But in some cases, like on metal surfaces, heat the base up to 250*-300* and...

As Brapperdoodle mentioned, the lines from the pump bulkhead to the engine bulkhead should always be straight. "STUFF" will always ruin your day when "it" gets caught up in a bend somewhere. Not trying to ruin your day here...You might be lucky and never have a problem. I used pour foam in my...

In regards to your pump setback, it doesn't matter. At this point it's the existing FX driveline angle you have to deal with. Because you haven't altered the bulkhead angle and lowered the motor mount pads. A lot of this has to do with personal preference too. Some riders have trouble...

Here's another option for Yamaha trim. I made this for a 2019 Superjet, using some factory parts. I don't know if there's enough room for the adjustment knob on the FX (didn't try it but it should work), it's something that's self contained and can be added later when you find out you boat...

In the beginning, I was on the path of a Superjet setup in the nozzle department. That turned out to be not optimum. The first nozzle I tried was a stock SJ reduction nozzle, with a Saito adjustable steering nozzle. That worked ok in the surf and at lower speeds. But tuning that nozzle required...

Drew, are you setting up any sort of tuneable/adjustable (not the lever operated kind) trim?

HeyBrapp.... Back in the day when I was pioneering different things to make the FX-1 more awesome, I was directed by other Superjet peeps that I should prop my FX just like a Superjet. Well, it ended up not the same. My 1st impeller for my 1" setback mag pump was a 13*-18*. The first motor I had...

I think this is the ski that the Tom21 FX is fashioned from. It was for sale at the 2012 Daytona freeride, and he was letting guys test ride it...https://hosting.photobucket.com/albums/vv292/Flash-FX/Daytona%202012/.highres/A53D1335copy.jpg

I need 2 for my Xs900 too...

Be careful with used o-ring style heads. They can be a source for mystery headaches that can't be detected with a compression gauge. .003" is the magic number.

Xscream changes the inner tube to be smaller, then adds the outer sleeve. (I've done that same thing on a couple "B" pipes) . The water stream is introduced between the two tubes. On the original style of stinger, it has water injected into the exhaust gas stream, somewhat reducing the area...

Had a bunch of small parts anodized years ago by these guys, located in Philadelphia. http://www.hillockanodizing.com/

Q1- Correct, the stock SXR800 impeller will not fit into a stock FX-1 122mm pump? A SXR pump is 140mm Q2-144mm will not fit a 650 (140mm) pump Q3- Why did they make the 1994-1995 FX-1 with a 122mm pump? Because someone at Yamaha engineering was trying to copy and improve a Kawasaki 440/550 race...

Sorry, No stock pump for me. I have been running a 144mm ,1" setback mag (Skat-Trak) for years. The prop ended up being a 16*/20* with my motor. The reduction nozzle is a Pro-Tek blaster max flow nozzle (un-machined bore diameter), with a Kawi X-2 trim nozzle setup. A must have. I actually...

Looks like I'm in the same boat. Good thing I have a machine shop & welding equipment to fix this brand new manifold. Sure wish that they DIDN'T POWDERCOAT it! Welcome to the Jet Ski World...

Every Yamaha based ski owner that works on their ski needs one... (excluding the big couch guys)

I love playing in the "kiddie pool" whitewater! He's doing Great! Got a good teacher!

Looking good! Finally!! Maybe you should start a new seperate thread with this new 62T style Zeeltronics CDI? This is sorta off the beaten path here. Does it come pre-programmed with a "MSD Enhancer" kinda curve as a baseline?
