I just hope one of those push in wire connectors didnt come loose when I put it all together it slid together without any force so I think it will be ok

why do you have these grey boxes? the 951 uses a black e-box and MPEM...?
I thought you'd swap all parts from a 951 ski?

The 951 and 787 hve similar timing and if you use a single coil ebox and stator, aling with a msd enhancer it will work perfectly on a 951, just have to set timing and looks waaaay nicer than a big black box and mpem siting wide open, grey box is sealed better and the inside of an hx hull is always wet if your a aggressive rider

Oh yea sorry there was a small spot that I missed on the back wall where the pump shoe bolted thru I just used cabosil in resin and made it like a paste and filled in the small hole/crack whatever it was ,I put about 14 hours on that ski this summer ,just put it up for the winter,loved every second I was out there on it so far, ive had radar'd/gps speeds a little over the mid 60's and im still running stock timing,I still could advance the timing some,I might do that next year, the best way I can decrive how it ride is, the black hx has a 787 and is a consistent 59-60mph ski and it pulls it like its broke, I put some umi bars little things like that,but pretty much left it alone, I never got any more video

Idoseadoo thanks for the comments it really is a head turner especially when it goes blazing by any newer gp, or ultra350 or yamaha supercharged skis, that think there's skis does 75mph because that's what the speedo says
I would say price all depends on how nice of a donor ski you have it defently needs to be a xpl, what I thought was a good 951 needing rings turned out $700 later after buying new oem crank and new top end, but at least I know what I have now, I ebayed the white pipe, Prok flame arrestors, fuel line, hydro turf, mpem with msd enhancer came from a member around $300 I think I paid for it, paint and bars it's the little stuff that adds up,resin fiberglass matte, I don't like keeping recipes because it's just a hobby and toy for me and if its fun it's worth every penny I spent on it but a close ballpark, I would say $4000, that's with me doing all the labor, price of HX hull, and XPL donor ski, everything.
It is well balanced I switched the battery and grey box over battery is on the right now to offset some of the pipe weight,it takes a full tank of gas of riding to get used to how it handles with the extra weight of course I did rip out all the foam also, I think it handles better with the extra weight I moved the motor back 2 inches to make the weight more center, and the sponsons are a must, especially for me at 155ish lbs, I did a 3/4 carbon fiber drop blade but this winter Im redoing the entire setup they will be 1 1/4in twice as thick and shaped a little differant, I think the 951 is only 30lbs heavier than 787 so it's not a major difference,
In the summer if you ever make it to biloxi,ms hit me up ill let you take it for a spin were out there every weekend rain or shine as long as it over 70 degrees lol, I'm hear to warn you tho once you ride it, you will never want to get on a stock HX again

I've actually never even ridden an HX, but now feel that I should be on the lookout for one. The X4's are great and all, but I feel that this is an even more raw experience. How much fuel can you put in it and how long does it last you? Does it dolphin a lot when you're just cruising?
Luvme4thamoney03

Once the trim gets setup correctly it doesnt dolphin at all anf when I first put it tigether and had no idea how it was gona ride it would only hop on wot runs, just for normal riding the twist trim is on -1 unlike the 787 is at a +3, I guess its all in your riding style hx has a 7 gallon gas tank, and if you jist cruise it does last a goos while ive done a 14 mile round trip just cruising and had matbe 1/4 tank of gas left, but also ive practiced on buoys at wot and burned an entire tank in about 2 hours on and off, a little course we setup,

And I always tell my friends thst want to try it out thst have never ridden on, to go out in about knee deep water and jump on it and just try to balance it first with motor off ,once you get that down, time for a run
