FX-1 Handling/hookup

Ok I have a few questions! I bought a FX-1 with all the sensible modes already done. B-pipe, am ride plate, scope intake greate, msd inhanser, prop (but don't no what brand or pitch), Foot holds.

I also bought a 2014 super jet as my main ride. I normally ride the super jet and let my son ride the FX-1.

The FX-1 definitely has a different riding style than the super jet. The super jet carves and the FX-1 slides more through the turns. My son is able to ride it fine with his feet in the footholds. But I tend to have more issues due to me weighing 230 vs my son at 170.

When I'm starting off and not on plane yet, the pump feels like it has a slipping clutch. Not hooking up at all. Once I get it on plain and only if I put one foot forward in the tray does the pump hook up good(then it's faster than &@@&. If I put my feet in the rear footholds its start slipping or cavitating.
Is this normal for the FX-1? Our is there something wrong like maybe a bad seal. What do you guy think? Maybe a shorter turn plate would help. What about handling . Is there anything I can do to improve it with out taking away from what a FX-1 is all about?

My super jet has a scope intake greate and -4" steering turn plate. So it hooks up all the time.

The fx1 has a few quirks like you have described in its stock form. The 122mm pump is a big factor in all of this. Some argue its efficient enough for the ski, If equipped with the correct swirl style impeller. You already have a the good parts installed that can really wake it up. If you want it to handle and lean/carve better. I'd recommend trying a set of tubbies or sponsons like many fx1 riders have installed. Shorten the handpole and keep in mind foot and weight placement do play a very large role in hook up. Its best to keep at it and get very familiar with it and how it reacts. Fx1's are loose and squirrely its not just yours. They all have a learning curve to adjust to. Some love them some hate them. The small 122 pumps can be swapped out and upgraded to larger with some minor glasswork if you go that route. A lot of guys do and are very pleased. The gain in hookup and tuning ability are huge. But not a must have modification right off the bat.

- Moreover, Comparing a fx1 to a 2014 SJ is not apples to apples. first off the hull is different and the weight placement is different. The SJ is heavier and has a factory 2" setback pump. The pump is also larger at 144mm. This is why you feel a drastic difference in hook up. The Fx1 when hooked up and on the pipe will typically launch and holeshot faster than the SJ. Don't be discouraged they are both awesome skis. Just get more ride time in and alternate. GoodLuck

Just curious, what swirl impeller is recommended for the stock pump to help overcome its limiting size? I don't think I want to do the pump swap on mine like I had originally planned

Where do you get the tubbies for the fx-1?. And do I have to remove the prop to find out what the pitch is?

There's a few sets of tubbies that will somewhat fit the fx1. Blowsion is probably the easier set to purchase and they own the " Tubbies name" if you go with them, Go for the tubby2s. Tom21 on here has a nice long sponson set that actually fits pretty good. I have them. Tom makes them to order.

-As far as seeing the prop pitch ID, you may use a small mirror in the intake grate tunnel and a flash light and take a reading of it.
