It will do it, but its not ideal...

Has a lot of trouble getting it up, but once you are on plane, it pulls it just fine...obviously there is no wake to be able to do any thing off of...

One thing to note - the speedometer is NOT ACCURATE when pulling a wakeboard...i told my g/f to keep it around 21mph and when she was pulling me she was going like 12mph which was killing my arms...so we finally figured out that around 30mph was closer to 21mph and felt right...problem is, when the jetski got on plane the speedo corrected itself and she started going wayyyy faster which made me hang on for dear life...when i told her to 'slow the f down', she said (after the ride) that she was only at 26mph on the speedo was trying to go faster!!!

Moral of the story, 30mph pulling up is closer to 21mph but on plane, make sure they know that 21mph is closer to 21mph!!!

Actually moral of the story, use a phone gps speedo

Have you ever wakeboarded behind a sea-doo before this?
how badly was it struggling to get you up?
was it cavitating and struggling to suck up enough water or did it not have enough power to get you up nicely?

My 3up gets delivered sometime in may and I am wondering how it will be for wakeboarding and tubing.

I imagine tubing won't be bad, but wakeboarding really relies on the initial power that the spark just isn't designed to do.

I have a yamaha vx110 that I have wakeboarded behind of...it doesn't struggle as much...

It wasn't caviting (although I wasn't driving the boat so I am going by assumption and what I heard)...it took a solid 5-10 sec for it to get my up...I had to make sure to keep my board angled up to help it get me to the top fast....
I wouldn't say it had enough power to get me up nicely...but it got me up consistently time after time so its definitely adequate to do the job...I weigh 200lbs fyi...anymore then that and I don't think it would have been able to do it...conversely, I think it would pull up someone 150lbs with no prob whatsoever..

Do you think that if you used a tuned Spark it would work better than the stock Spark? I think the moral of the story might be to get something different if what you really want to do is pull wake boarders.

I had to tow one of my ski's and found the same speedo issue. It said I was going 42MPH towing another ski and I know I was not.

Is there not a way you can calibrate the speedo on the spark?

I am planning on doing the tune eventually, maybe this will bump up my time table a little...

I do think the tune will help, maybe to the point from taking it from 'borderline acceptable' for wakeboarding to 'acceptable' (if the line is thin enough)...

even my jetboat isn't the greatest for wakeboarding behind (although it has sufficient power)...

Not understanding the speedo issue. I thought the 3 up speed is determined by gps.

no way it can be...i tested the speedo myself by giving it backward momentum and then letting it idle forward....i went from negative speed to no speed to positive speed, the whole time the speedo reading 3mph....gps would have gone to zero at some point and then gone back up in that situation...

 

[Dmshirkey]

My guess it would be purely based on RPMS

You guys sure ur speedo is set to mph not kmph? Sparks are built in Canada and lot of brp products ship in metric units

GPS does not give the speed of the moment like a wheel would. It averages over a short period of time. I will take mine out with a gps and compare readings. The manual says with the 3 up H.o. the reading for speed is gps. The display panel shows a GPS. Since it's not displaying a position I can't imagine a purpose for it rather than speed.

GPS is actually measuring your speed a second in the past. Basically a series of continuously measured split times.

Gps is part of the ibr package. Otherwise the speed is calculated via rpms. In my garage it will not get a gps signal and will show 3 mph.

Were you in Sport mode when having trouble getting up?

 

[jpg.crna]

^^^ I was wondering that too. Were you in sport mode? Has the person towing you, ever towed anyone on a sea doo before? This thing can jump straight out of calm water with 200+ pounds on it, I just don't see it having that much trouble. I know water drag is a different story but it should have plenty of power for this.
