Bindings too far forward

@Jboss Just gently heat the sole with a heatgun or even a hairdryer to peel it of the plate and relocate while the glue is still sticky.

@Jboss Look under the rear plate, there may be holes pre drilled in the plate making it possible to move the rear boot further back on the plate.

@UWSkier Plenty of non cat 343s out there w/ ZO.

@Than_Bogan What you just described is actually three possibilities.

@Horton Questioning Pigozzis streak of 4@41s ? How about when Freddie ran 41 twice @ Bennets some five years back, his first time ever running it ? Can't recall there was any controversy with those scores. Oh wait, Bennets is not located in Europe!

I don't see it, Sacha and Pigozzi did what they always do. Freddie is on fire, maybe settled in on his relatively new ski?

Wow, what a slalom tug that would be. Better than most if not any of the new boats out there today.

One thing you can try is listen very carefully near the FCC when you turn engine off. If it sounds kind of like the fuel pump is running for a second or two after you turned the key off it indicates that air has entered the fuel rail and will spin the fuel pump backwards a bit because of the compressed air in the rail. This will make injectors shut off at random but the fuel pressure can still show a good reading. Drove me nuts when it happened to our club boat.

@dbutcher A quality valve as well. Big difference between quality brands and cheap ones.

Yes you can test them, just pointed out that engine harness needs to be connected in full and engine running while you measure. Measure volts against an open loop will not reveal bad contacts. Obviously what triggers your symtome is heat, whatever cause it is probably there when you start up in the morning on the verge of making a symptome. Like I said there is no set voltage where things go bad but if it gets low enough it will cause problems. I'm not claiming the relays are the culprit but they will eventually need a replacement anyway. And yes heat affects resistance and therefore voltage in electric circuits.

@Wish You can't rely on a code reader. If the check engine light don't go off, there is no codes stored. I had one relay go so bad it only fed the fuel pumps with 4 or 5 volts and no check emgine light. Those relays feeds your engines entire fuel and ignition system including the ECM and they are prone to get bad with time. There is no set threshold in voltage where things stops to work, system voltage is supposed to be around 14 volts and when the points in the relays get burned/ corroded enough the voltage they put out drops- can only be measured during workload. When the voltage drops to a certain point things stop working, at what voltage? Who knows but don't expect fault codes for every imaginable fault that may occur.

@Wish Have you replaced the 2 relays located near the ECM yet?

I don't get that surf boat slot argument. Are the boat companys trying ro sell a fact that there is a demand for surf boats they can't keep up with?

@skinut Why did you change to B2 ?

@skihacker MAP sensor is more critical than TPS.

Like @jercrane pointed out it looked like Thibaud is on the GTR. For skiers at the level of Sacha and Manon we can never really know what ski they use. Unless you are an industry insider.

Kjellander 3@41

Ha! Was totally expecting a giant gator lurking the shore with some FedEx trucks in the background

@Sethro ZO use GPS as speed baseline. Wind and current is irrelevant, it only affects the skier but the boat speed remains the same.

@Wish That pitting won't affect anything. We're talking 50 000 volts, the spark will find it's way regardless. Coil can still be faulty though with internal issues.

There should be an intake air temp sensor also that works the same way. Is the sputter occuring during a constant load or when accelerating? If it is during hammering the throttle the TPS (throttle position sensor) comes in to play.

@Wish I would not completely rule out the temp sensor either (temp sensor for the fuel injection system). A long shot yes, but it's difficult to come up with good advice when the sputter is not experienced first hand.
