This has always been a problem, but this weekend it was especislly bad, keeping me from traveling over about 20mph. What happens is, when im cruising and hit rough chop, my speedometer shoots up to the 60's-70's then the throttle backs off itself, im guessing because of some sort of speed limiter. This has always been a problem, but I usually only had the problem once every few hours. This past weekend was especially choppy. When I went over 25-30 mph, it would happen. I have done alot of searching and have not found another person with the same problem.

Speedometer problem with my 2011 gti

not a common problem, your speedometer is gps based so it should work perfectly. it sounds like a bad or loose connection possibly at the back of the gauge cluster where the gps unit is and that is where I would start. is it still under warranty? If all connections look good, you will probably need a new gauge which is over $600.

it's inside the gauge cluster, not serviceable. I would take it to the dealer you bought it from and see if they will work with you on it. They could easily pull a gauge from another unit and put it in yours just to test but I doubt they would.
I just sold a 2011 GTI SE 130 yesterday.

sounds like something with the dash.. loose connection.. loose screws to the gps unit.. somethings not right with it.. i would play around with the dash and see where that gets you
I just want to make sure I am following you correct?
Basically, if your speed (gauge) shows a high speed your ski automatically slows down, correct?

What gets me is,,, if I understand it right, the 2011 ski uses a GPS signal for it speeds.
It is almost as though if your impeller looses grip, aka jumping or in chop, and revs up that is is somehow connected to your speedo.
The ski has a speed cut off as well as an engine over rev limiter. Which, are separate but could easily be tied together at the MPEM/brain.
What I would do is, look at a wire schematic and see if you can find the wire that feeds the MPEM from the GPS speedo, ( not the output ti the gauge), I would disconnect this wire and then go for a ride.
Though it does not make great sense, it is slowing down because it THINKS it is going too fast. By disconnect this wire I'm thinking it will isolate the issue down to either the limiter or the speedo.
Thoughts???

i think the gps transmits a signal every 1-3 seconds.. i know the more expensive ones are faster and the less expensive ones are slower..
so lets say its in the middle at two seconds.. that would mean you would have to be out of the water spinning that fast for around 2 seconds... how big is the chop you ride in? 1-2 foot swells?
i think maybe disconnecting the wire it might have an opposite effect of what were trying to achieve? it may just throw a CEL and end up in limp mode trying to protect the ski and the rider ? to me it seams more of an electronic issue with the gps.. i know with my garmin 76 once in a blue out of no where itll pop to like 170 mph on the max speed setting..
it almost sounds like the gps is loose and is smacking around when bottoming out of a swell at higher speeds.. im curious if you go slower of the swell at a lower speed like 10-15 if it will still happen

it's not revving up at all, the gps is just freaking out due to hitting waves(possible bad external connection or internal issue) and giving a high speed signal. this speed signal is tied into the ECU electronics so it backs off the throttle due to conflict in the system due to higher speed than it should be going.
does it do this in touring, sport, and economy modes?

I'm going with a poor connection at this point.
Get it in the water, leave it in the trailer, give it some RPMs, start to wiggle harnesses and tapping on brain boxes and what not. See if you can get it to hiccup.

I was able to repair a non-functioning speedo pickup on my 2001 seadoo by disassembling the potted electrical parts and replacing them, a zener diode and a magnetic sensor IC. Kinda thinking I wouldn't be able to accomplish quite that degree of success with the 2011 seadoo, so now I think maybe I'd do well to hang onto my old boat as long as it can still pull me out of the water on my slalom ski. Heck, maybe I'll even buy new seat covers for it once they crack and/or rot away.
Thanks for the heads-up.....

Right, new aftermarket parts can be available if the market is sufficiently large to warrant manufacturing them, parts can also be obtained from boneyards, but parts made somewhere in outer space or on another planet may be constructed of unobtanium and I'd rather be boating as opposed to waiting for parts arrival via international shark train courier or something.
Well, maybe it's worth it, IDNK

Rpm limiter, friction limits your speed.
Check the trouble shooting guide. It could be that your oil level is low. Newer engines have a oil pressure cut out. High oil flow with choppy water would starve the intake if the oil is low. Plastic or FOD in the oil res could float over the intake - not likely, but....if someone wanted to screw with you. When you slow back down the oil flow would catch back up again and run normal. Maybe a candoo reader could read the last 60 sec of running when it does it again.
Good Luck, Doc
Whats happening is all sea doo's (maybe all watercraft manufacturers?) are limited at 68 mph. The speedo shows 70-80mph, which is higher then the speed limiter, so it kicks the throttle out. This boat realistically only does 55-56 mph at its best. The speedo inaccuracy is the problem.

Would the Candoo unit remove or switch off the speed limiter?

all newer skis.. are governed by the coast guard i think? to be limited to 68
i candoo will not raise the speed limiter.. you would need an ecu reflash
